I have run the 215s in my 30-06 with IMR4350 powder and CCI 200 Primers. Was able to get 2800 without bad pressure signs. No extraction issues just alight and I mean light smearing on the case head and slight flattening of the primmer.
I also Have tested the 215 with up to 65 grains of RL26 Powder with Fed 215 Mag primers . I am going to finish testing when the weather warms up. But this is what I plan to stick with. I am getting a little over 2850 with 65 grains with no case head smear but a very light primer flattening. And I mean very light. I cant get enough powder in to get over pressure. I plan on test loads from 65 to 65.5 Grains and going with the best one.
First load with 56 grains of RL26 and 215s with Fed 215 mag primers saw 2373 average on the crony. So for those wondering I did start low and worked up.
A couple more things to note. I have a 28" 1:10 twist barrel. I also Am jumping to the lands with a .250 Jump. Yes you read that right a .250 Jump. My COAL is 3.640" So I am also seated out a ways already. More room for more powder.
