The BRX and Dasher have enough capacity to use RL16 which gives a little more speed with less pressure but it's too bulky for the straight 6BR. My guess is you'll end up in the low 2800's. If it's the only bullet you have, it's a good one! Around .020" off is where I'm at.I remember in one of my barrels getting 2900 with 105 at 29g Reloder 15 . Max is 29.9. But I’ve read where guys were using 30.5 and up but I’m not going to ruin my brass .
