Good luck and let us know how you get on.

Thanks Tikka,

Results so far, COAL = 2.240
9.0gr H110, 3 shots, 1MOA
1088, 1047, 1058 fps

9.5gr 2205, 3 shots, 1MOA
1089, 1075, 1091 fps

So far this is the about the most accurate bullet I've tried. A little fast, I always get vertical stringing if I try and reduce the velocity on the 220 SMK's even if I seat the bullet back, tried a compressed load too. I might try a different suppressor, mine's weighs about 450grams. Did you have any work done to your rifle other than the new barrel?

Thats definitely better, the other thing I can suggest is weight you brass into 2 or 3 weight batchs that made a difference for me.

Also I run every batch through a chrony and have each batch separate and use one batch at a time then go onto the next, I've got 13 or 14 different reload batchs of 194gr Lehigh ME, 208gr Amax subs and 125gr BT supersonics. It keeps the ES down for each batch and better MOA. It only takes a couple of clicks to re-zero between batchs. Maybe a lot of work but need best accuracy for hunting with 300 Blackout at distance.

Work done on rifle was trigger lightened by me, and halfcock bolt, new barrel with it threaded for a ODL suppressor by the gunsmith.

I've been weighing brass too, found a big variation with Hornady brass. For your long range work, did you find your drop matched your calculated solution? Mine's about 1.5Mil lower @300M. I might need to do the tall target test.

Did a tall target test and had an error of about 1.5%, accounting for that, G1 BC of 0.27 matches my drop at 300m. about the same as flat nose 30/30 of the same weight. https://www.sierrabullets.com/store/...0-30-170-gr-FN a bit less than advertised 0.630. holes a little bit oval shape out of 1/7in twist. Group was 1.8MOA (3 shots)

With the 208gr Amax is bang on out to 400m on steel, not that I would shoot an animal that far. It's nice to know the exact trajectory.

I'd like to see (from a distance) anyone loading 300 BLK supersonic with 208gr projectiles.

You could do it once with each rifle I suppose.
