Re: Scratching my head with 300 RUM
I'm running 95 Grains of Retumbo, Fed 215M primer, Rem Case, 200 AB out of a custom built 700 Rem w/Hart barrel 26" and getting an average of 3220 with no signs of pressure at all. Your load seems a bit higher but that could be the chronograph's error on either yours or my set. I agree it does seem a bit fast from what I have seen from other rifles. Still its not all that bad if your not experiencing any pressure signs. Loose primers, hard bolt lift etc.
On the Ramshot Magnum I have not had any experience with it but those velocity's seem scary. Were you getting any pressure signs at all?????? Odd, really odd.
