I guess the Ultra Match has gone through changes over the years and is now being made by RWS as UM-22 and is basically their R-50 ammo and comes in the red plastic holder. Just wondering if the old stuff was a different manufacturer and why the lower velocity and not as good accuracy.

I will check shortly and report back. I'll also get the DA when I chrono the new stuff, as I forgot to yesterday.

That doesn't list the Federal Ultra Match UM22 load but the BC for it is .138 but the .139 on JBM works perfect. The BC is not the .092 listed on the Federal site.

I just ran a .138 BC on my Ultra match, and with my old velocity figure of 1016, got 8 mils at 200, which allowed me to hit just fine. Heading back out and intend to chrono the new stuff. A buddy is visiting from out of town, so we are kinda shooting all over the map, instead of just focusing on one or two things. .22's, 308's, .38's, 9mm, more .22, more .308, etc... Good weekend.

The new ultra match, in the red plastic trays, ran 1043 fps avg for the 10 shots I tested. SD was 10, DA was -850.

How was accuracy?
Most people agree that .22's need some rds down the barrel when swapping ammo around, before they will shoot to their potential. In this case, the first 5 rds were .45, the next 5 were .41, and the final 5 that I shot for group were .35". All done at 50 yards. I wouldn't think reconditioning the barrel would matter much in going from 5 year old ultra match to current ultra match, but I shot the HV Match in between, as well as the Hunter Match. Neither grouped very well. Maybe all use the same lube, IDK. MAybe the groups have nothing to do with different ammo, IDK. I do know that I will be shooting the current stuff exclusively from now on. :)

Went out yesterday and tried out the Wolf MT Extra. Perfect day as winds were reasonably light and from the back. First time shooting it though the Annie other than a few shots at 50 yards to confirm zero.

CB gave me a predicted drop at 300 yards of 14.8 mils when using 1033 fps avg MV. This jived well with @lash charts for Fiocchi Match and Lapua club which are marginally faster @1,050 fps. Actual DOPE was 14.6 mil.

Happy to say that the ammo was consistent and produced very few flyers. At $75/brick, it is a good deal.

While searching for info I came across a large BC chart for Rimfire stuff and found it very helpful. I’m using applied ballistics and couldn’t find bullet length data anywhere .... I’m not sure if even needs that info but the drops seem close without it. Anyway here is the page I was referencing. http://krsmart8.wixsite.com/smarts-research/rimfire-ballistics-coefficient
Another very helpful chart. Thanks!

And thanks to @SLG and @Nik H for the data. I will definitely be able to provide an updated chart or charts soon with the extra information.

As of right now, it's beginning to look like the older Federal Ultra Match was faster than the newer product manufactured by RWS? If that is the case as it seems, then I can create a separate column for the new UM-22 next to the old for comparison and validation by those shooting them.

lash,

Just in case I missed some data that you are referencing, I thought I'd make sure that my previous posts were more clear. In my one CZ 452, with a 21" barrel, the older Ultra Match was slower, at around 1016. I forgot to measure DA that day, but the conditions were very similar to the next day, which was around -850. I also did not record the SD, but it was high, around 24.

The newest Ultra Match, in my one gun, shot about 1043, with an SD of 10. DA was about -850. Groups were a fair bit tighter with the new stuff, as you might expect.

Other people may have different results, and I imagine that a shorter barrel than mine would be a drop faster. I'm going to check my 16" CZ 455 in the next day or so. Thanks again for putting this stuff together.

Yes, I have this one already and it is a great list that I use with Coldbore to develop drop charts. A more theoretical work on the aerodynamic characteristics of .22LR Match ammo was conducted in 1990 by the Ballistics Research Lab of the US Army. It is a real interesting read and it has some very good data for Match ammunition.

Enjoy

The RWS loaded UM22 in my 18" rifle is right at 1100fps.

I use Wolf Match Target and found this chart and works for my set-up CZ455 VPT 16.5” barrel.

Thanks. I tried the Target and it was good ammo. I find the Extra produces fewer fliers so I have been focusing on that. I am going to use this BC value and see if the come-ups are matching the field data I have collected.

Thanks again

I have tried SK Standard Plus and Wolf Match Target I may try the Extra maybe even give Lapua a try just to see the differences.

Eventually I want to get a Lilja Barrel. Shooting 22lr is addicting 😀

FYI, I just ran the Wolf extra in my calculator trying to match Nik's results and backed right into the 0.130 BC that DXT's chart shows. So that seems to be a good BC. I'll add the Wolf to my charts. I should have an update of some sorts today.

Do you think my slightly longer barrel is slowing the bullet down enough to see the 50-60 fps difference that we are seeing? Could of course also be that your match grade barrel is just better as well.

Apparently . . . it sure looks like that's what's happening. There's a substantial velocity difference between my 18" barrel and my 22" barrel as you can see here in the Average velocity column with 4 different cartridges that I recently fired (measurements taken with Magnetospeed V3):

There was an article about this topic. I thought I had it but it may be in Steve Boelter's book. There was definitely a decrease with longer barrels

I will see if I can find it

Okay, so finally here are some updated charts. I revised the first chart by removing Federal Match and Ultra Match, as they have their own chart. I added Wolf Extra MT, added the BC used for each and fixed a couple fumble fingered errors. Then I created a separate chart page just for 4 different versions of the Federal Match and Ultra Match just to capture some of the different options in velocity out there. At the very least it demonstartes how important it is to know how fast your bullet is going when it leaves the muzzle. See attached:

Is there a schedule for these matches? Only about 2.5 hours from me.
@Rob01 , we have a Facebook site "Cvrpc Tsc" and we just finished our first match of the Year. I am actually getting ready to update Practiscore with the Match Dates for 2018.

April 14, 2018 (Greg Myrick - Winner)
June 9, 2018 (2nd Match)
August 11, 2018 (3rd Match)
October 13, 2018 (Finale)

Best 3 scores of 4 Matches count for the overall!

I will let you know when the PractiScore is updated!

Pretty cool stuff all around, thanks to all of you involved.

I would love to cut my barrel down to 16" and thread it, but I am afraid of messing with the accuracy. Usually not a concern, and many of my centerfires have been cut down with no ill effects. Often quite the opposite actually. Anyone have any .22 experience in this regard?

Also, I've been pondering the 50 yard zero deal. My gun has a 30 moa base, and my NF has plenty of adjustment, so I'm not concerned about running out of elevation with a 25 yards zero. When I ran the numbers in my Kestrel today, the difference was really minimal anyway. I started thinking that a 25 yard zero is possibly a better option, as it would limit environmental effects (much like a centerfire 100 yard zero). Any thoughts?

Cool brotha.. I will get you in there.

This is the first year of using Practiscore so Pre-Registering on Practiscore helps us get an idea of how many shooters we will have, but you can just show up as well. The Facebook will send out an event invite for each match as well...

We will only go to full Practiscore Registration if we start bumping up against our max shooters...

I've heard arguments that support your choice including that it eliminates negative drop prior to your zero. I also agree that even at 50 yards, wind can affect the lowly .22, so you have a point. I, personally, do not have enough experience to either support or negate your argument.
