I am preparing to tune a new rifle. I have already tested 8 different types of ammunition...5-5 shot groups. Then tested the best 4...same method, then the best two...same method. So, 15 five shot groups of both Lapua X-act and Lapua Ctr-x.
Both lots are approximately the same age and speed. I tested both under the same conditions. There is very little horizontal dispersion between the two, with a slight edge going to the X-Act. The difference in group size between the Ctr-x and X-act is almost all due to vertical dispersion, with the X-act winning by about .08. The performance of the X-act would be competitive in an ARA Unlimited match with the proper operator (probably not me.): and that's with a naked barrel. I would obviously like to use Ctr-x (cost and availabilty of test lots). Should I tune with the Ctr-x? It will be much easier to measure any change in vertical dispersion. I should still be able to use the X-act with equal or possibly better results.
Does anyone but the test center offer actual test lots of X-act ? I mean in times of normal sanity. I use Good Shooting, but I don't believe they ever offered test lots of X-act.
Thanks,
Gerry
