With the results you mentioned, definitely go with the smaller charge. The difference in velocity is not worth the abuse your brass will take. Also you need to leave yourself room for wet/hot days. Too many people try to get every last FPS they can, only to cost themselves headaches in other ways.

I was wondering, Magnum primer in a 6.5CM? Better now.

I use small rifle magnums in my CM. CCI 450's

Abnormal pressures can come from several different sources, one of them is the use of too hot a primer. Think about it. Deviating from an ignition source not designed for the specific caliber can cause the very problem you are having.

That's why if you intend to to magnum primers you have to redevelop the load from scratch. I don't think anyone here is saying just switch to magnums and see what happens with the OP's current load.

I was running non magnum primers and getting pressure super quick. Did find a carbon ring and scrubbed the crap out of it which helped big time. I did find that the gun builds carbon really easily so I have to clean thorough almost every 50 rounds.

Model of rifle 215 m would be a federal large rifle magnum primer

Correct, & I dont understand why the OP is using them for this cartridge & for this powder!

Clean it more often , eventually the lands and grooves will "burnish" and you may be able to extend your cleaning intervals.

I may be wrong here so if I am please correct me someone but I was told early on as a general rule of thumb less than 60 Grains standard primer over 60 grains of powder a magnum primer

Especially if you shoot in cold weather.

How do you load that much powder into a 6.5cm case?

 

[Paper boy]

And NO, that' not correct. What reload manual do you use??
