I just ordered a Proof S.S. Med. palma26” 22 BR 7Twist. .050 free bore from Straight Jacket armory. I am really excited to launch some 75 and 88 gr eld bullets. Will be screwing it on to a Bighorn Origin it should be quite the rifle.

I want to try the 75 on prairie dogs mostly for splat factor. But yes the 88 will be superior from a bc standpoint.
I am tempted to build a lighter 22BR and use the 75 for coyotes. I am pushing them 3025 fps out of a factory barreled 223 already though.

I tried pushing the 75 eld to 3000 FPS and beyond in a bolt gun. I could not get the sub 1/2 Moa accuracy that I desire. I went back to a 50 or 55 vmax and voila sub 1/2 Moa. I am thinking the 22 br will give me the accuracy that I desire I guess we will see.

Nick at Straight Jacket has the 22BR figured out. I stayed at his place in Evanston Wyoming while we were over to shoot the Hornady PRC match. His reamer specs are the ones I use as well. Great guy, makes a great rifle.

I've fooled around with the 75gr bullet, it ended up not really making sense to run it as a target round. The 88gr just seems to be such a sweet spot for this rifle right around 3000fps, give or take a little for shooting steel. I do run run the 75gr Hornady BTHP Match in my 223 Ackley Improved trainer. They match up nicely at that 3k velocity mark to my BR and are super cost effective bought in the bulk box of 4000 count. But for a primary bullet the 88gr ELD-M is still relatively inexpensive. And running Varget, which isnt difficult to find, most fellas will land somewhere between 28.5 to 29.5 as their accuracy node.

And I've heard great things about the 50 and 55gr varmint bullets from this round. A varminter seems to be where this caliber got it's start.

Was going to fix my match load today with VV N150 and 80 gr Eld-match.

Found out the other powder bottles i had was from another lot, so full panic mode(no time to fix a new load).
Rushed to the range and tested it, same low ES and SD, just got some more speed(3130 fps instead of 3100).
Group looked good, never measured it but was around 2" or so with 10 shots on a newly painted steel plate att 330 yards.

28.6 gr N150 and just off the lands.

I am using the standard 22Br Manson Reamer with the .050" freebore. It has grown almost .020", but most of that was at a high rate of fire team match I did when it was almost 100 degrees out. Burned through 24 rounds on some stages in less than 3 minutes.

I would go .254 neck diameter next time.

I have a new 22BR reamer on order.
We have been using a .100fb.
Very pleased with the 88s. new reamer will be .120 and a 255 nk so none of the necks need to be turned.
We found with the .253 we had to turn the bottom 3rd of the nk to keep them cycling smoothly without pressure.
Hard lift for young shooters sucks.

The 80 gr eld-m seems to work fine out to 700+ yards, had pretty good results on the long range targets.
Had no problems hitting a 6" plate at 600 yards with some funny winds.

So going to keep this load for the competitions with mainly shorter ranges.

The 22 BR will do just fine with the 80gr bullet. To suggest otherwise is just silly. In fact RE17 will push that bullet past 3350FPS in a 22BR. The BR is the perfect case.
That fast?! What length barrel? Load data?

I know that RE15 has fallen out of favor relative to Varget and RE16 bc of the temp instability, but has anyone been able to find some success with it? At the very least I figure I can use my remaining batch up as a practice load.

New guy here. Been looking on the Hide for years and finally signed on.

Getting a .22BR barrel put together right now (Bartlein, by Bugholes), with 88's in mind (7 twist). Not real sure exactly what throat I'm going to wind up with, but I told Greg I was planning on 88's and possibly 95's, and didn't want to have to turn necks.

I ordered 200pcs of Lapua brass yesterday, along with a Redding FL sizer and a Forster seating die (figured I'd get a neck die setup after I get everything necked and get through the first firing).

I've read through this whole thread and was wondering if anyone would care to elaborate on their die setup for necking down and then sizing after firing.

Thanks!

I used the standard .252" neck reamer on mine and I didn't have to neck turn, buy my loaded rounds are around .251". It has the standard .050" freebore, so I started out loading them short, but there was plenty of room for 28.8 grs of Varget and 27.3 of H4895. I would probably go with a .254" neck so you have some more clearance on a loaded round.

I use the standard Redding 22BR full length dies for sizing new brass down to 22BR. I just picked up a bushing die and haven't used it yet. If you neck down with a bushing die, I feel you have a better chance of getting a ring at the neck/shoulder junction and would have to neck turn to get it taken care of. I know a guy that had that issue and he is running the .254" neck and I believe a .100" freebore.

I shot a high volume team match with my 22BR in June in 97 degree weather. My throat grew .040" as we had a few stages where I shot 24 rounds in less than 3-1/2 minutes with H4895. I switched to Varget and am currently playing with Rl16 with pretty good results.

Got my 22br running with about 550rds on it now. We used a .254 neck reamer with .100 freebore. I ended up having to neck turn though. Recent batches of 6br brass have been about .002 thicker in the necks than my Gunsmith has ever seen. I shaved off about .002 and it cycles perfect now. 28.8grs Varget under the 88ELDM getting 2970fps after neck turning. Just won my 3rd PRS Regional Series match in the SE. The 22br is growing on me and having a 2nd barrel spun up to have ready for the remainder of the season.

Need to fix my modified case gauge or make one from a fired case, probably supply a few pieces to my Gunsmith to keep records on throat erosion.

Okay. Stupid question time.

Bear with me, the only time I've ever necked anything down was some W-W .270 brass to .25-06. It worked well, but that was years ago and I've not necked anything down from one caliber to another since. Never neck turned anything.

I lubed a case body and inside the case neck with Imperial sizing wax. took the expander out of the Redding FL die, and gradually ran it up into the die until it "kissed" the shoulder (it looked like it bumped it about .001" or less on my cheap calipers with the crappy hornady shoulder measuring tool). I had a very small ridge (donut) at the neck/shoulder junction. Another potential issue is that my brass measures .009" shorter after running it through the die. When I necked .270's to .25-06, they were LONGER (?). Is this a big problem? Any way to fix it?

Sooo, I guess I need to go ahead and turn the necks. Never turned necks before. I do want to be sure I've got this down. First, neck turn a couple thou off the cases (before sizing, looking at the K&M tool and the RCBS ball mic), then size. Correct? Or do I size, then turn off the donut?

Thanks for helping out someone new to the wonderful world of wildcatting!!!

Sizing 6.5 Grendel down to 22 Grendel I ended up with the same junk. I neck it down just a touch undersized and then expand the necks using a paired expander/ turning mandrel to ensure proper fit on the turning mandrel for neck turning and to push all the excess to the outside. Then I neck turn all the excess material and donut off.

As far as being shorter I wouldn't stress it as long as it isn't excessive. Just don't want a carbon ring to build up. 10 thou shorter than the reamer print is as far as I would want

I necked down virgin 6br brass, ran a .223 mandrel through them, fire formed them on first firing, then ran the expander mandrel through them and turned brass until I had 100% concentricity and cut about .030 up the shoulder. Annealed, sized and loaded.

Which reamer print did you use and which mandrel and sizing bushing have you found works best? I'm probably going to go down this route, too.

.254 neck with .100 freebore. I've used the Forster FL Non-bushing die the first 2 firings, but switching to a Redding FL bushing die with a .245 bushing now. After NT a .221 Mandrel is fine. Loaded neck diameter after NT is .248. For Neck turning I'm using the 21st Century powered Neck turning lathe with the 22br kit.

Took a peek at me powder inventory and played with a necked, virgin case to see how much (roughly) it would hold of each.

Looks like around 34 grains of H4350 and RL22 to the bottom of the neck. 36 grains of LeverRevolution.

Going to look for a good load for 88's at about 3000fps (24" barrel).

I've got a whole 5 pounder of RL22. I may try it with 88's, starting about 32 grains, but wonder if it wouldn't be too slow. Might try about the same with 4350 (maybe start at 31).
LeverRevolution is one you don't hear much about, but my AR likes it with 75's. A bit faster than 4350, denser, and meters like water through my old uni-flow. It's also usually easy to find around here. Honestly, it's the one I want to start with, guessing around 31 grains.

Anyone dabbled with any of the above? Read some comments on cooler burning ball powders, wondered how the above (ball and stick) would relate to throat wear.

Oh yeah, almost forgot, any primer preferences? Got plenty of 205's and 400's, along with a few 450's, BR-4's, and 7-1/2's.

Should have my barrel in a week or so. Can't wait!!!

Also got my K&M neck turning kit.

Virgin brass measured .013" on my ball mic. I ran a piece over the 6mm K&M mandrel. Cut .002" off for .011", chucked the shell holder assy. in my cordless drill and let the neck do a few laps in a piece of 0000 steel wool, then ran through the Redding FL die, then back over the expander stem. Finished thickness was .012". Is this good or do I need to back it off a bit?

Also, still getting a ring at the neck/shoulder junction barely detectable by my thumbnail, but I THINK that this is just where it's not going that far into the die. My shellholder is hitting the die, but the shoulder has not moved. I'm GUESSING that will probably fireform out when the shoulder pushes forward.

Follow up, decided I needed a little more bullet for a local venue that has a lot of long range positional stages. Tested out the 95SMK and at 2850fps (restricted due to current Freebore Dimensions) it tested out with a .310G7 BC and was confirmed out to 1135yds without any stability issues.

I'm going to have the Freebore extended with a throating tool on my current barrel as well as a second barrel I'm having spun up to test and then order a custom reamer based off my findings.

Does the better BC of the 95SMK beat the extra velocity of the 88ELDM?

What reamer would you guys use for the new Berger 85.5 hybrid?
Obviously haven't had hands on and probably won't with them costing the same as 105 Hybrids, but with all these 85-95grs bullets I'm leaning towards a .200 Freebore spec. The 88ELD and 95SMK are looooong! They'll work with .100fb, but you will have a ton of bullet left in the case. Even running .200fb you're not hitting 2.5COAL. Gonna be doing some tests with the 2 barrels I have then ordering a custom reamer based on my findings next year.

My 22 Dasher 95 SMK reamer is .235 works with 88s good too. That puts my 95 just above the neck shoulder junction seated touching the lands a .250 would give you a little more room to adjust for jump.
In a straight BR .175 should get everything above the donut area and work with a wide selection of bullets

I have been running a 22 Dasher this season. Rl 26 gets me 3120 with a 95 smk
I’m sure 3200 would be possible with 88s
Rl16 node is 3095 with 95 smks...26” 6.5T Barrel
Do you have any problem with blowing bullets in your 22 Dasher and 6.5T with the 95smk or 88 Eld?

Thanks for the response! I have a 22Br 6.5T 5R bartlein coming from area419. I’m excited to play around with the 22BR.

Bunch of short throw 22 BRs. Mines going on a Tikka. I've been wondering lately about a 22 GT. Doesn't make any sense on the surface bc it should be very similar to a 22-250 ....but if a 22 BR can do X then a 22 GT should be able to do at least X but without mag kits....😆
