10- 300 blackout with Nosler 220g ballistic tips over 9 grains of H110.
10- 458 Socom with 300g Hornady HP over 40 grains of CFE BLK
5- 338 Lapua Magnum with 250g SMK over 104 grains of US 869
I used some BL-C2 before in a pinch for 308 and they were really spicy. BL-C2 is really close to CFE-223 on the burn chart. If you use it for 308 I would start a little under recommended charge weight.
Using fire formed and weighed Hornady 6.5 creed brass and 38.00 grains of H4350, 140g match bullets set to 2.820, I achieved 8.3 SD on a 4 shot group. I think it would have been closer if I had warmed up the rifle first.
New scale got here fast! Loaded up 4 rounds to start. New federal match brass, 42 grains of 4064, CCI 200 primers, 2.800 OAL.
Cheap Hornady scale : 22.40 SD
TRX-925 scale: 13.46 SD
I know it’s only 4 rounds but I’m impressed so far. I’ll work up more loads for the weekend!
The RCBS 505 is accurate to .1 grains. Am I chasing my tail if I want to make my loads accurate to .02 grains? I've tried new brass vs once fired, weighing brass, weighing projectiles, different powders, all with the same inconsistencies when it comes to FPS. I'd love to get some single digit...
