Thread: Too fast and dangerous? 7mm Rem Mag, 180gr ELD-M, RL26

I have always been able to achive book max at least. However.... the other day I loaded up a pet load I have of 51.7gr 2209 with 140 Interlock for my new Kimber, this load has shoot really well in every 270 I have had, it shot well in the Kimber also, but... I loaded up a couple at the book max of 52gr 2209 (only .3gr more than the pet load) and fired off the first one, it was wildly off target compared to the lower load and the bolt was very very stiff, primer was super flat. This makes me a bit nervous about using the pet load now in this rifle so I will start again or possibly just back off to 51gr and see if its still nice and accurate. Amazes me how it can go from fine to crazy with .3gr more powder
