Just wondering if there is any reason to not use federal GM205M primers in a 6mm Dasher with 105-108gr bullets. This is not for a target rifle but a 20” barreled lightweight rifle. I have lots of these primers on hand because I used to have a 223 rem. Are these primers too soft for Dasher pressures? Thanks.

I've run em in mine with no issues but both rifles had tight firing pin tolerances. Kimber Montana and the PF M70 I had Gretan bush.

Wouldn't hurt to give them a try.

Thanks Higbean. Mine is a Kimber Montana as well. I have some 6 BR brass loaded up with 65gr Vmax with the 205M for fireforming. I’ll start with those and see how it goes.

That's all I use for my match loads, as well as the majority of the point blank PPC BR shooters.

Most of their loads would scare the schitt out of you......

Thank you, that’s good to know.
