6.8 Western Powder Choices

[Cliffdog]

I started with Ramshot Magnum in the 6.8 Western a couple years ago because that was the first slower burning powder I could source during a time when supplies were limited. I've since added H1000 to my stock and use it in a 300 PRC. I've tried it in 6.8 Western but circled back to Ramshot Grand in the 6.8 Western with a 151 HHT hammer at 3220 fps.

Just curious what is the powder charge you are using with grand? I’ve been trying to develop a load with this powder but not having any luck. I’m shooting 150 cutting lasers.

Running 67.1 gr for that load. I had worked my way up to 3300 fps but got too much pressure sign including primary extraction issues - so I dropped down.

Interesting. I tried 67.1 of grand but it didn’t group for me. Also was running about 3033 fps. I’m shooting m70 Winchester with 1:8 and 24 inch barrel. I’ve had good success with h1000 at 60 grains. 4 shots under 1/2 inch. 150 cutting edge lasers at 3.036 coal and 150 badlands precision super bulldozer 2 at 2.95 coal. Both shoot under half inch at that powder charge. Just looking for more speed.

I use Ramshot magnum and N565. Just shot this load today @ 600 yards with my Browning X-Bolt McMillan with Ramshot Magnum and 165gr ablr's. I really enjoy this cartridge!

Best powder I could get going out of an 18" 6.8 western was Ramshot Magnum. Shot lights out with the 175 Sierra. No a speed demon as its in a 18 inch barrel but super accurate.

How many grains of ramshot magnum and what seating depth? I’m getting decent groups with ablrs seated at 2.850 oal over Retumbo from my browning but not as good as what you’re getting there!

I would have to agree with the A2200. I load 90 -120 with it and get good velocity and sub moa groups. I have tried H322 and it is accurate but has anemic velocity. RL10X is close to A2200 in accuracy but a little slower in velocity. H335 & A2230 didn't work for me at all as far as accuracy. Shooting a Bison 18".
