What charge weight for the H322? It gives me good accuracy but not the speed of other powders.

30.5 grains H322. I have a 22" barrel and have been getting 2900-3100 fps during development. Some powders gave me the speed I needed, but not the accuracy.

Does anyone have information for the 6MM DTI shooting 65 grain V-Max? I've heard Benchmark is good with these but I have not seen anything about this particular bullet.

Anyone tried AR-Comp yet in the 25 DTI?

I've been thinking about trying it for heavier bullets. It is a reformulated RL15 and supposed to burn faster, more like Varget. I tried RL15 and it was way too slow.

What is a DTi? Rifle and or Cartridge? Sounds interesting don't know anything about them. So an education would be nice. The only stupid question is the one not asked?

A series of wildcat cartridges based on a necked down 6.8SPC case, by a company called DTI.

Thanks for information!

Some 25x6.8 loads with Leverevolution in an 18" BHW barrel. Federal cases with Wolf primers (NCSRM). Rounds are loaded 1.846" length to ogive with a cutout magazine to allow the length.

Nice Speeds! What cases and primers are you using?

FC cases and Wolf primers. I edited the post with more info.

Some CFE223 data for comparison. These are probably the two best powders for 100gr and heavier in the small case.

Anyone try GS custom bullets? Their 80gr is similar in length to the gameking at .95". I might buy a box or two and give them a whirl, but figured I'd see if anyone here has anything to say about them.

Got my GS Custom bullets on Friday and loaded a small batch. Hope to get them out and shoot them soon with the chrono. Apparently the 67gr is the correct bullet for the cartridge since I was hoping for heavier for hunting, but hopefully the solid bullet and extra speed make up for it.
