whichever primer size you end up going with make the last step in the load tuning primer testing. Seems certain cartridge/powder combos prefer certain primers. My 6.0 creedmoor loves Remingtons with H4350, none of my other loads can stand Remingtons, go figure

Just a thought, but my Savage 10 FCP loves H4350 with 140 grain bullets. Shoots one jagged hole groups. I have always used large primer brass, both Hornady and Starline. Never any problems or reason to try small primer for me, it works great as is.

Ocharry, you can purchase straight from Starline if you need.

ocharry, same here 3 degrees this morning, have to go to range Sunday to test my 7 mauser.
When you gwt some fired brass, do a water weight test to see what actual capacity of the different brass is.

I have talked to a few friends that use SRP brass. They have had some problems piercing primers. Mostly Remington and Federal primers. Same loads and guns, but no piercing with LRP brass.

I did get some star line brass from midsouth today....they had 100 lrp for $46 I think it was...got a few other things too...
I was watching a YouTube video about this stuff...and the guy was doing load work with small and large primers....some of the small primer loads were hang firing....now the temp was in the 20s....some of them didn't even go off....seems he was having best luck with Remington 7 1\2 and CCI ar (think that was the one)small primers and it looked like case volume had some effect too...and temp...seemed the colder it got the worse it was...but those problems didn't show up with large primers He opened some up and the powder had turned brown...just didn't light off....was a pretty good video...he was using several different powders too Was pretty good videos I thought..( he had several )...that's why I had to ask you guys I just want the shells to go off when I pull the trigger...so for now all the brass I will have is gonna be large rifle primers....like Reynolds said why would this cartridge be any different than any other....great point...for me....I dont plan on doing any competition shooting with this rifle ( for now anyway) and for sure no over pressure loads But hey I dont even have the rifle yet....poop.......but I am still reading and following all the comments from you guys Ocharry

Guys....i want to correct something i posted earlier...
I went back and watched one of the hang fire videos again....the small primers he had the least trouble with was the Remington 7 1\2 and CCI 41....not CCI ar....my bad...I guess the 41 was designed for the military 556 round...I'm guessing it is hot....like the 7 1\2 ???? As Reynolds has attested to If you guy are interested in watching any of these....I typed in 6.5 creedmoor hang fire.....and Johnny's reloading bench came up....they are pretty interesting Ocharry

If you call CCI, they will tell you the #41 is identical to their CCI 450, their small rifle magnum primer, except that the feet of the anvil are shorter and splayed out further to reduce sensitivity to meet military sensitivity specs for floating firing pin guns. But otherwise, it is just a civilian primer. Actual military primers are made without nickel plating on the cups and they are qualified by fairly extensive testing of large samples from each production lot in all manner of temperature conditions and to meet functional reliability standards in addition to the sensitivity tests. The average shooter wouldn't want to pay what it would cost to put consumer primers through the military level of qualification.
