That is awesome. You have no-doubt defined my opinion of the M14/M1A. When tuned, it is an outstanding semi-auto precision tool. Not to mention the fact that you provide the proof. I have only proven my Colt 901 at half that distance. Well done, sir.

Thank you, sir! I just got back from the 600 yard range and took out the first rifle I ever built. I haven't played with it much lately and decided to give it a spin. I ended up shooting a 1.7 MOA 10-shot group at 600 for a 100-4X.




I need to get a tuned load for this one and see if it can do any better. This was the first time shooting the 169 SMK through it.

Tony.

Another for the discussion.

Tikka T3x Super Varmint, 223 Remington, ammunition IMI 77 grain HPBT-Match. Position kneeling with rifle supported on a tripod with Arca rail clamp. 100 yards.





The group actually consists of 12 shots, and if I could eliminate the two “flyers,” the 10 shots in the middle would measure 0.821 inch center to center. That’s pretty good for that ammunition and my shooting from a semi-supported position.

I fired these two 22 Long Rifle 10-shot groups with my Winchester model 52E rifle supported by a heavy bench rest at 100 yards. They were the last two groups of a 125 round session testing different higher quality ammunition types.





What I found particularly interesting (not to mention surprising) was that the group on the left was fired with Lapua Center-X ammunition and the one on the right with SK Standard Plus ammunition. The center to center group sizes were 0.721 inch for the Center-X and 0.812" for the Standard Plus. Both are very good results for 22 Long Rifle ammunition at 100 yards, but even though I shoot a lot of the Standard Plus with a different rifle and the 52E usually does very well with the Lapua, I didn’t expect them to produce such similar groups—and why?

Although the availability of both varies greatly at different times, the online prices for 50 rounds that I found were $8 for the Standard Plus and $18(!) for the Center-X.* The two groups pictured were the best for the two loads, but two other Standard Plus groups measured 0.962" (with nine in 0.700") and 0.852" (seven shots). The two other 10-shot groups with the Center-X measured 1.109" and 1.003", or actually a little worse than the much less expensive Standard Plus groups.

* Center-X is not the most expensive Lapua 22 Long Rifle ammunition. X-Act goes for about $37 for 50 rounds. (I bought one box one time. It didn’t perform noticeably better from the 52E than Center-X does.)
