I ordered 5 boxes of the 212s at the sale price and all they did was cancel my order. Even when it said 5 in stock. They said no go on backorder. Just straight canceled. Won't order from them again..
Sorry to hear that. I ordered 5 x 212s and 2x225s that showed in stock as well as a case of 225s as a backorder. The case of 225s was delivered this past week and the others have ETA of Wednesday. I was honestly surprised but thrilled at the deal. Also got 300 rds of 6.5CM Am Gunner for a steal.

I just use the factory ammo to shoot to fire form my brass and then hand load. At that price it's too cheap to not buy just for the brass for skipping handloading for fire forming. I bought all my stuff from Midway when it first came out.
Hanks. That's my plan. Just need to buy the initial factory ammo.

Assuming you mean 225s?

You ordered a case of 225s on backorder and they already shipped/delivered before the "in stock ones did??

Was there a limit to how much you could back order? Did you order in store or online?

Looks like it's a backorder situation, but

Match 300 PRC for $24.67/box at SWFA

Same $24.67/box price on Precision Hunter
Any idea why they were on sale?

sorry, yes, 225s. I had one initial order just of many things that showed as in stock. I only ordered up to the in stock count. Then, after seeing that I could backorder, I figured I'd try for a case of the 225s to see what happened. They created UPS labels for both orders on Monday, 7/22. But, for some reason the order with the variety of different ammo did not actually get to UPS a few days later. The order of the case of 225s, which was supposedly backordered, did get to UPS on 7/22 and arrived to me a few days later.

Was there a limit to how much you could back order? Did you order in store or online?
There may have been a limit. I just tried a single case.

No idea. Just saw an email from them and happened to get to site early on in the sale and stocked up.

Been going back and forth with SWFA customer service and they insist that the sale does not include any backorder product and will not honor the sale for the items that showed in stock when ordered. Wonder how many others got the shaft also.

Glad you got the deal though!

Anyone else have 29-30 inch barrels shooting 230 A-Tips yet with H1k and RL26 that have any velocities to report?

SWFA has annoyed me before and I normally don't order from them. A while back they had a good deal on a nice scope listed in stock but then couldn't ship it within 3 weeks. These prices were just too low to pass up. Sorry they jacked others over, I had pretty much expected I'd be screwed out of something in my order. Your post made me go back and look to confirm for sure that my case was charged at the sale price.

Their site was a bit funky during the sale. Items seemed to go out of stock and come back in during the few days of the sale, even over the weekend when I doubt anyone was actually updating inventory. The sale email did state it did not apply to backorders so they must have had a short lived glitch in their ordering.

Bought 200 230 gAy tips to try in mine along with 200gr Sierras, 215 Berger's.
All testing was done at 850 through a Chrony. Retumbo, Rel26, H-1000. Cycling through 50 pieces to see end of life. The 230s shot ok @2920 but never as good as the 225s, Bergers, or for that matter, the 200 grain Sierras.
Finally got the SD down to 4 and ran the gAy tips and 225s out to 1650. Easy button with the 225s @2900 with Retumbo. I have 150 230s left if someone wants to play with em.
PM me. I'll be out of town till mid August, then I'll list and ship.. I have several other Samplings of 30 Cal bullets I tried as well.

What barrel length were you getting 2920 with?

I emailed ADG and asked if they have any plans to start making 300 PRC brass.
They responded and said they're considering it, but customer input drives what they make.
So all you guys with a PRC need to start hounding ADG!

Been doing this since December. If ADG doesn't do it Peterson would get my money if they did first.

I have settled on a load for my 300 prc. Haven't been able to get out to distance but Reloader 26 is legit. I also got my hands on some of the new Aluminum Atips.

I was down to a SD of 2 to 3 using 74.2 to 74.6 gr Rl-26.
Average velocity is 2920 225gr pills

Aye, 74.3 with A-tips and 74.6 with 225's seem to be the sweet spots for me. I'm playing musical scopes right now but plan on getting more 300 action after the Vortex Extreme.

I'm going to do a new ladder with my 8x68 fire formed and RL26 as soon as I can get out to the range. I'm considering doing it with Berger 230s... I know, change one thing at a time, right?

Would you mind sharing what primer, and your OAL?
That's awesome SD and Velocity!
I've got an 8lb Jug of RL26, and a pile of N570 that I'll be using when my barrel is done in a few weeks.

I have one in 6.5 300 and I loaded 3 rounds of 225 Hornady 300 prc in mag well. It would feed them if barreled in 300 prc. My current 300 prc is a bug nut Bartlien from Greg at SPR on a defiance deviant and the short bolt throw and smoothness of the weatherby is better. I will get 300 prc barrel from Greg for the Weatherby once it's shot out.

We ordered a 30" Bartlein barrel for the AX MC in March from Mile High and it arrived right before our planned 3 day weekend shooting trip. I picked up a Sidewinder brake and couple of boxes of ELDM 225s. The weekend was a blast and all the sudden it was Sunday and we had not shot the 300 PRC. So I screwed it in and it shot like a dream. The stats were not all that impressive but I have to remind myself we were breaking in a new barrel. Average = 2941, SD = 18.2 FPS, ES = 94. The last 10 were Avg = 2956, SD = 15.6, ES = 56 but they included the high MV outlier. The last 5 were Avg =2952, SD = 7.0, ES= 16.

I don't know if it was due to the mass of the AX plus the heavy barrel and a great brake or whatever, but the recoil was mild. It was easy to spot shots. We love it. Eventually, I'll handload for it but for now, we'll just stretch it out on factory ammo.

Thinking of using the 300PRC as a suppressed hunting rig. Seems that it really needs a long barrel to take advantage of a full powder burn, has anyone tried a 22” barrel suppressed? Those that are really familiar with this caliber, what your best guess? 2800 FPS?

Thanks for the info. I saw some pretty inconsistent results with the latest batch of 225 eldm I shot. My original lot I was in the high single digits SDs and average half inch 5 round groups. Some more. Some less.

I was really thinking of a 29-30 inch barrel handloading the 230s hoping to get 3k+ fps. If I couldn't get it there, then it may not be worth it for me. Haven't seen it yet from anyone. I may be just sticking with the 26" and 215s.

I'm getting 2965 fps from my 26" AXMC. I was shocked at the lack of recoil compared to my 300 Win Mag on the same rifle. I just wished I had saved the money and not bothered with the 338l setup. Consistent Hits at 1500 yds with 10mph full value wind. Rifle is a JOY!

Because we can’t get it to 4000fps
However.....
You might want to keep tuned for the new high pressure proprietary cartridges that will be available shortly:

You might just get close to your 4000 fps with the right monolithics...

Have been loosely following various ultra-high pressure concepts and while I'm sure there are materials out there that can handle it, I suspect barrel life is going to suffer considerably-- and it won't be cheap at all. 4140 and 416SS are already near their limit at 65,000psi on the inner (bore) wall.

Keeping an open mind, though. Curious to see what comes of it. Not convinced it will be here for the long term, yet.

Hi,

You are correct, there have been all sorts of concepts, etc for years and years :)
But the NGSW and its' high pressure 6.8 cartridge is changing the norm of pressures.

What most of them did not do though is to approach the situation in its' entirety but instead focusing on 1 aspect of it.

Changing barrel alloys alone is a band-aide approach.

But being able to change projectile composition and engraving friction while being able to use a faster burning powder but less of it, yet achieve higher MV changes the entire results and approach....instead of going bigger and bigger case designs with more and more slow powder.

It also has a LOT to do with the cartridge designs themselves...that is how/why BR guys can push their 6BR, etc to 65k pressures but yet sit there and reload 5 pieces of brass all damn day without much hassle at all. The design itself lends to liking those pressures.

Sincerely,
Theis

I want 3000 fps out of a 29-30 inch tube or doesn't really give me anything over 300 win mags. If I can get the velocity without a bunch of pressure why not?? I was shooting 2000+ yards. So I'll take the higher BC pills and velocity. 3k doesn't seem like it would be that hard with the PRC and a 29-30 inch tube. If you can get low to mid 2900s with a 26 inch tube and factory 225s... the 3k hand loads and longer barrel seems well within reach. So I don't think it's asking a whole lot for less then 100 fps with hand loads and 4 more inches of barrel? Maybe it is.. guess I'll just find out for myself.

Maybe try the Warner flatline 198gr bullets in your 30" barrel (assuming at least a 9 twist) and see if you hit the velocities you were interested in?

Last weekend I finally got around to chambering a 300 PRC barrel for my DTA. I used a PTG saami reamer and a 10 twist K&P barrel(6-groove cut barrel). It finished at 27”.

Off to a good start. Here’s the first four rounds through the barrel with Hornady match 225 ammo. A bore sighted shot, and 3 round group. One round was slow and killed the ES/SD. Velocity average was 2873.

AFF9F338-B181-428F-B89D-7791433EA868.jpeg

I shot 5 more rounds of the same ammo at dots (top row, pic below), and the average jumped to 2907 FPS. As with the first four rounds, one slow round in this group killed the ES.

Below that are two ladders with 230 and 215 hybrids in half grain increments of H1000. All virgin brass and bullets jumped .030. Charge weight and velocity is written under each dot. Not sure what happened to the last round of the 230 at 76 grains, but it was oddly slow. Shot 19 was a ND. I interrupted my trigger squeeze to do a breath cycle, and capped a round off. Doh!

Edit: Just realized that I didn’t write the 215 charges or velocities on the target. It was 75-77.5 grains, and topped out at 2947FPS.
881F3923-B1FB-4200-AE77-F476BE0CDB79.jpeg

I’m still a grain or two from max for both bullets with H1000. Primer pockets are like new. Case head expansion numbers for both bullets maxed at .0003-.0004, which indicates the pressures were pretty soft. Now that I’ve got a little Experience with the PRC, i’ll go out and do a 500 yd OCW. I also have some other bullets to test, as well as RL26.

The DTA is a very new platform for me. I’ve only shot about 100 rounds through it with the factory 47 Lapua barrel, which shoots great. Easy gun to shoot well in general, which should help the 300 testing go well.
