Best consistency can vary from load to load, powder to powder etc... 450s and M41s and BR4s have done so bad over the years they have only won matches for folks. Rem 7.5s are ok also though I rarely found as good an accuracy as with others. So I'll stick with what has given results for us. And don't get overly carried away with ES/SD. It has to be good to reach distances, though I don't shoot 223 past the 1000 yard line, but some of the very smallest ES and SD have not been the most accurate loads. The best way is to look at ES/SD, but pay more attention to how the groups are, and what the vertical is at the max distance you want to shoot. That will tell you a lot more than what a number on a screen every will be able to tell you. For safety though, just stay off the first two I mentioned and you will be fine.

It can made a good bit of difference in group sizes. You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.

I have been using the WSR in my 25-45 Sharps and 223 loads recently after reading that the CCI 400 were not recommended for the MSR platforms. Of course that was after shooting about 500 of them first in my 223. I only use CCI 450 in MY Grendels as I dont shoot the number of reloads through them as I do the 223. It isn't energy that kills, its holes.

Some bullets are finicky....to date, the only thing I've found the 64gr Nosler solid base will shoot at an inch for 5 shots is with IMR-4895. The 60gr Partitions like it better than ball powder as well. You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.

It changed years ago, from a silver outer cup to a brass colored one. The brass ones are softer, like the federals. When you are on the firing lines and see untold numbers of shooters with ARs you learn a few things, your world opens up. Only slam fires I've ever seen were new brass colored WWSR and Federal primers in the AR15 platform. Nothing against either primer, but soft is not, IMHO, safe in a floating pin gun like the AR. That said testing primers can show you a lot with different powders and loads. Opened my eyes MANY years ago. Yep, I have favorites, but I never discount running through primers as an accuracy test, with the ARs I would usually not do this up close but on the mid range lines past 300 out to 600, and plot groups, it can sure sway you now and then. You cannot discount where the holes are in the paper. We can keep Larry Root and all his idiotic blabber and user names on here, but we can't get Ralph back..... Whiskey Tango Foxtrot, over....

Though it was the ranges first 200 score at 600 ever. I kind of had issues at 1000 with seeing well enough with stock irons to hold elevation that next day.. I won the Palma service division, but came in 3rd in overall IIRC, though I won 800 and 900 IIRC, 1000 I just could not hold elevation. But it was fun. David is a great guy too. As was his father.
