PRIMERS: Magnum or Standard for 6.5 PRC

[Drjones65]

I am shooting a Bergara Wilderness Ridge 6.5 PRC. (24" barrel / 1:8 twist) and I am trying to work up some loads.
Question?
For those that load this caliber; do you load with magnum or standard primers?

I load Federal primers and I have the following primers on my bench:
GM215M (Magnum Match)
GM210M (Large Match)
210 (Large Rifle)
215 (Large Magnum Rifle)

Do you vary your primers by the powder you load with or by the charge or by the bullet weight?

Thanks for your input!

I use 210m in mine 156 elites and get single digit ES . I've tried the 215 m but my ES with them was huge and didn't shoot nearly as well as the 210m
Some guys use the 215 with good luck but not for me.

I use 210M with RL25 and a 140. You will be fine with either.

Test both standard and magnum with the same loads…there will be a clear winner.

Cheers.

 

[Sending156s]

use lapua, gm210m, rl26, & 156 EOLs

 

[Levi8599]

Standard for me. BR2 or 210M

CCI250 for me and RE26 best groups and es.

 

[300WineMag]

Fed 210m, H-1000, 143 ELD X for me

 

[WYO300RUM]

use lapua, gm210m, rl26, & 156 EOLs

Ditto but with ADG/GunWerks brass.

Your rifle will answer your question.

I use 210M with RL25 and a 140. You will be fine with either.

My Ruger Hawkeye shoots best with 210M's. This is with H1000 behind Berger 140 grain VLD'S.

I've used CCI magnum and BR. Both work well, but SD is a little better with the BR. FPS is slightly higher with the magnum, but the lower SD is more important to me. But if I didn't have the BR, I wouldn't sweat using the magnum.

Only what the reload manual for the bullet you are shooting. That is,,,,, Sierra manual for Sierra bullets. Barnes manual for Barnes bullets, and so forth.

I use Federal 210M with all bullets in the 6.5 PRC except the Hammer 124gr. For the Hammers I have followed their advice and use magnum primers, specifically the Fed 215M.
