Any way i have discovered a slight edge in accuracy and a rather extra reliable pounds Using the BR2s however I don't weigh many primers, it had been additional from curiosity than have to have .
I made a decision to mixture the load information mentioned on 6mmBR.com for many cartridges, to see how persistently Every single variety of primer was referenced. I selected 6mmBR.com, for your handful of explanations:
(I had only said which i was having to use many tension on the deal with to seat primers in professional scenarios.)

Must you use primers apart from CCI or Winchester brand name, make certain that you feed them separately and, just like all primers, hold them inside their authentic container right up until you rely on them. I have not discovered Federal primers to get better or wors than other manufacturers."
The Federal primers are created from softer metals they usually use a far more sensitive priming combination than any one else. (That is why the race gun shooters utilize them, their guns have very light springs which cause light primer strikes.)
The slope of the line drawn in which peak blast pressures (Y axis) and primer mass (X axis) intersect is a upward inclining straight line suggesting that peak blast pressures are specifically related to primer mass.
A number of people could possibly have guns like my revolvers with mild hammer springs. Little doubt, dependability and accuracy troubles will exhibit up when primers with tougher or a lot less delicate cups are employed. All through my tests, I found When the hammer did not strike the primer hard more than enough .. it would make the primer detonate with way less flash. This results in lousy powder ignition or perhaps a click-no bang. When hammer Vitality is strong more than enough for any good good primer hit, there's nearly no variance while in the flash in between brands.
CCI, Federal and Winchester. All have worked perfectly for me but as GP100man mentioned start low and operate your loads back up To make sure you're Okay with force. If you want them then get a bunch so you don't run out for the few years.
It doesn't make sense to me that Federal would make a rather distinct sized primer/primer pocket on function. I am not a generation engineer, but I can't imagine that doing this would help save them ample income to justify the expense.
Every severe hand-loader must unquestionably study the total check outcomes to understand Laurie’s methodology and obtain all the small print. This is an important examination, with major conclusions. But If you're able to’t spare enough time at this moment, Here are several highlights under:
The larger everlasting cavity could lead to speedier blood reduction. While these an edge Obviously exists, its significance cannot be quantified".
Which was with the LC ammo plant. Their primer division blew up in 2019. That started out the Gov't buying all the things from commercial suppliers. And it has not stopped but.
Primers even have extremely insignificant differences in diameter earning seating resistances apparent - diameter dimensions vary under .001 but even this federal ammunition primers small quantity might be found on seating. My past primer seating chore indicated that WLR primers took noticeably much less exertion to seat than CCI 200's.
