6mmBr and RL-17

[6mm Shooter]

I finally got to velocity testing RL-17 in my 6mmBr with 105 A-max's. I started at 33gr and worked up to 35.5gr. 33gr averaged 2960fps and the loads at 35.5 averaged 3105fps. These velocities were out of a 30" barrel. It looks like I am going to be able to shoot a nice light load just above 33gr for 3000fps depending on accuracy. I know the barrel shoots the a-maxs well at that speed but the pressures were high with RL-15.

Tried a number of powders for loads, just seeing what they do, but never R17.
Those are pretty over pressured loads in any other powder, I've tried.

35.5gr of RL 17 will fit in a 6BR case?

35.5gr was half way up the neck. I saw more pressure with 30.5gr of RL-15 than this load of RL-17
