.22 LR Ammunition Accuracy — 55 Ammo Types Tested

Didn't find many Bleiker rifles on gunbroker.

lol no kidding? I think they're around 5Gs in the US...if you can get them at all. I appreciate the variety of ammo they used in the test though...

I think I found the post you are refering to: http://forums.accuratereloading.com/eve/forums/a/tpc/f/8711043/m/9871088921

A lot of work with this test!
I always question how these test are done. 10 years or so ago when I traveled a bunch to benchrest matches around the midwest, I did a bunch of testing during the winter months in a local indoor range. 2 or 3 hours every Wednesday afternoon until I couldn't see any more.
Did the tester start with a clean bore? Did he shoot fouling shots of the brand he was testing before going for record? How many? Then did he clean again before testing the next brand so it starts with the same bore condition? If one doesn't clean then the next brand is being tested with the lube of the previous ammo in the bore with the lube in the bore changing with each shot.
I noticed the Lapua Center X at 50 yards shot poorly the first group and then got much better. That could be from not cleaning or not fouling. But I don't see that pattern on many other brands. I wish the testers would give more detail on their process.
And again I notice the rifle has a tuner. Did he make an effort to tune each brand before his record groups? Also I have found action screw torque can effect group size and can be different from one lot to the next of the same brand.
Speaking of lots, could be he had a lot of one brand that suited his gun and a lot of another brand that didn't (to fast or to slow). But it does tell you what worked for this one gun. I do know that in testing lots in my two nearly identical rifles (same action and barrel) that sometimes they would both shoot the same lot of ammo the best and then with another brand they may shoot different lots the best. Bottom line this test show an accuracy level that can be attained with this ammo but only testing in your own gun will you find which is best for you.
Most of the top benchrest rifles are shooting in the high 1's or better and they don't cost $5,000 . Maybe $3,000 for a new build. But they don't work for Olympic 3p as the Bleiker.
Also if I read his post correctly he measured groups outside to out side and then subtracted .22 . That doesn't work. I've made that mistake my self. If you measure bullet holes in paper with callipers they will vary all over the place. The thinner the paper the smaller the hole will measure. Sometimes only .18 or so. The tool used for group shooting is a calliper with two circles. It doesn't sound like it would work but it does cause the human eye can line up one circle on another, even partial circle very well. http://www.neiljones.com/html/target_measuring.html

Rich,
He does have a Neil Jones measuring device. He did not use the tuner adjustments. He did tell his cleaning method and he did shoot a box of ea. lot first before measuring groups. I think that if he had a true BR stock, a good rest setup, and used the tuner it would have been different and better.
Keep up with the thread ocassionaly as he is going to do the same test with different rifles.
