Why wouldn't you just use whatever ammo is most accurate at 50 yards? I say this because it is related to my experience in not having 100 yards to shoot at. Whatever ammo I had that shot the best at 50 yards, I would use it no matter what the distance is?

I find it hard to believe that if ammo "A" is less accurate at 50 yards then somehow at 100 yards ammo "A" will be more accurate.

It does happen. Eley sub-HPs shoot better at 50 yds than CCI-SV and sub-HPs through two different 64 sporters. But at 100 yds the rank reverses for both rifles. I suspect this is b/c the exterior ballistics/wind susceptibility are not equivalent.

And, fwiw, the published exterior ballistics (ballistic coef) may bear little relationship to a) what you chrono and, b) what you see in drop at your range. When I determined BC for CCI-SV was surprised to see it was higher than expected.

An analogy (yes, exaggerated) might be comparing .308 with 125 gr and 190 gr MK loads at 50 or 100 yds, then seeing what wind can do to those 125s when shooting at 400 yds.

[QUOTE=j
Supersonic transition...has become a regular topic with the local benchrest guys.
Consensus is that it does not have as much effect on the trajectories as is claimed.
Cartridge defects and wind appear to be better explanations than the previous research done on the smkbthp.
Different bullet shape produces different results.[/QUOTE]

I mentioned on another topic that in my mind the jury is out about the transition zone but I can tell you this. When shooting highpower matches most guys used the 30 caliber 168 grain bullet up 600 yards and switched to the 178 grain for the 1000 yard matches. Even though the 178 started slower, it still retained supersonic velocities at 1000 yards. The problem as I see it, with the .22LR bullet shape is whether it really is effected going through that zone as a sharp pointed bullet. I don't know and I don't care. I would never use HV ammo at any range in competition. And in my long range silhouette matches from 65 to 200 meters, I've won 45 of 60 matches never placing lower than third using ammo in the 1057 avg, 27 fps spread and 7.06 SD.

When I first received my order of SK Long Range, I naturally tried it out at 50 yards, the range at which I normally shoot. Four 5-shot groups ranged between .750 and .930, not exactly something to write home about. I then moved to our High Power (100-200 yard) range to see what the SK Long Range would do at 100 yards. The results were the groups shown on the right side of the pictures on my earlier post. It appears that there may be a real difference in this ammunition's performance at the longer range over its performance at 50 yards. I'll have more results next week when I get out to the range again.

I guess there are all types of theories out there and all levels of experience when it comes to ammunition, accuracy and what is best at 100+ yards.

I based my original post on 37+ years of smallbore rifle prone and position competition experience. For conventional prone, targets are posted at 50 yards, 50 meters and 100 yards for the standard course of fire for a 1600 aggregate. In short, 3 of your 8 targets for the day are fired at the 100 yard distance (with 20 record shots per target). Most prone matches are won - and lost - on the 100 yard stages. With that said, the same shooters practice regularly, know how to read wind and mirage, understand the impact of light changes and test countless lots of various manufacturer's ammunition to find what works best in their rifle.

There is virtually no HV ammunition used in prone competition by top shooters. HV ammunition drifts more at 100 yards than SV. Can you use HV at 100 yards and shoot good groups? Yes, but the consistancy is typically not there with HV vs SV. Why fight more battles than you really need to when starting out?

Go past 100 yards? It is not my game. As a general comment, I would be hesitant on who's advice I would take to heart. The number of variables on rimfire accuracy and their impact at longer distances are easily magnified and results are not linear. Even very experienced shooters can become perplexed in challenging conditions.

The OP inquired "what ammo for 100 yard groups?". Stay in your lane 'bro....go with the SV offerings no matter if you are using a 10/22 or a match bolt gun. Much higher probability of better results.

Regards,
ken

This is my experience with SK Long Range Match. I was not impressed. It was too inconsistent. All shots from a bench with front and rear bags. Best ever group from rifle and shooter at this distance is 0.223". Best 11 5-shot group average, same range, same setup, 0.459". SK Long Range Match from best to worst at 50 yards:















100 Yards 10 shot groups (sort of):







With this group, I have chrono data. Shot velocity: 1045, 1060, 1056, 1089, 1047, 1031, 1064, 1057, 1060, 1057. One shot did not read. Avg 1057, Hi 1089, Lo 1031, Extreme spread 58, SD 14.9



Another 50 yard, 5-shot (except one is 4) groups, 4 targets. Notice the flyers are all at the point of aim. I had dialed low on purpose.



One more 100 yard, 10 shot group. My point of aim was 6.5 inches up. I was looking for the actual drop at 100 yards.

At any distance past 25 yards, with the 22lr, if y'er ammo isn't assembled properly
and produces inconsistent muzzle velocities, results on target will not make you happy.
If you aren't competing and it doesn't matter, shoot whatever you like.
Just don't be surprised by odd strays that aren't y'er fault.
If you are a bit OCD and insist on doing the absolute best you can at 100 yards,
no matter the cost, then the top grades of RWS, Lapua and Eley will do better in most situations.
Unless....you get lucky and get y'er hands on a brick that shoots above it's grade. It happens.
The makers of the cheaper ammo can't get it wrong all the time.

Post #9 lists drifts at 100 and 200.

I shoot at 25 and 50 yrds. I know that I need to crank UP 12 clicks when going from 25 to 5 yrds. What can I expect to get to 100 (in or 1/8 clicks)? Some fellows want me to shot eggs at 100 yrds.

When I shoot the 50/100 yds. side matches I need to dial in 6-6 1/2 MOA to go from 50 to 100yds. I shoot CX or SKPM or RM

Using 1080 fps 40 gr subsonic 22lr from 50 tp 100 yards I get a drop of 3.9249" Eggs at 100 are a blast, we have small stell eggs 1.5" high at 200 yards. The best is golf balls with a big screw eye & a loop of masons line or heavy cordlooped over pipe about 12" to 18" away from the pipe. They will spin like crazy & take many many hits

Test different SV ammo. Mid level/grade, out to 100 meters, in my specific sport, with me and my barrel, is great.

I had used CCI Blazers, not to shabby with me and the barrel. Good practice ammo, you might say, out to 100 meters.

I wonder how many times this question has been asked???

I suggest Fiocchiís 320 - itís about $9.99 per 50 and I have had good luck with it out of a Kimber 82G and a DíOrio Turbo.

What does your rifle like? Our CZ455 loves Aguila Pistol Match. The B22 rocks with the Geco Match. They both shoot silhouette and are averaging 17-20 (15yo and 13yo).
