Re: CCI vs Remington primers for 300 win mag

Ron would you by chance be using RL 19, 22, or 25 in your 7mm rm? Or perhaps a ball powder? I have noticed that those 3 RL powders and several ball powders from W748 up to Supreme 780 do not care for 215s, they have an inconsistant burn because the lightoff is so fast the powder column burns unevenly/erradically, in those cases a hot but more controlled ignition is better, I no longer use 215s unless I cannot find 215Ms, there is a big difference in my findings that the 215Ms are much better controlled and ever so slightly cooler than a run of the mill 215. I see that you actually mentioned the match version so when I encounter what you have, I simply switch to CCI250 or #34s, if the consistency is still off I go to the WLR. The PMC (russian) standard LRPs are like match grade CCI250s but good luck finding any!

Re: CCI vs Remington primers for 300 wi n mag

Backwoods- interesting. i am using re-19. i developed the load quite a while back , the load works good i hate to change . my kenton knobb was made for it. i believe there other powders "better" i would like be using an" extreme powder". the time i spend developing loads i could actually be hunting . the norma manual shows the 215s as being much better than anything when temp is below 0 though with their powder. i do hunt at times when it is cold.

Ron there are two powders you can likely duplicate that load with that aren't classified as "extreme" powders but they are not to sensative, Imr4831 and Hybrid100v. On the extreme note H4831 non short cut with WLR or fed210M primers should come in pretty close.

Re: CCI vs Remington primers for 300 win mag

i like them in this order
fed match mag
fed mag
cci mag
rem mag
ww mag

thing is though is that even though i like the feds best it doesnt guarantee a certain load in a certain gun might prefer another. I done load workup and just bumped the charge up a gain of powder and found that that changed which primer did best. But that said if i look at my load data for all of my mag rifles the feds ted to shine a bit brighter.

[cleaning the brass with a sonic cleaner] Don't forget to dry lube the inside of the necks after cleaning with the sonic-cleaner. It has a tendency to clean to well. The bullet needs a little lubrication to seat smoothly. After being fired the powder residue is good enough. Randy
