6mm-223

I have tried H335, 2015, TAC, 4895, x-terminator and Varget with marginal inconsistent results. The 87 grain I have been using are the Hornady SP. I should probably weigh them to check the variance. Maybe its a bad lot. What bullet are you using? What barrel length? I should see if Sierra makes a non-varmit in the 87-90 range.

By the way mine also likes 2015 (25g) behind the 58 grain Zmax.

I have also been playing with the notion of ordering a 24 inch blackhole (another upper) to see if it would handle the heavier bullets better.

I have a Dtech built 1:10 20" full bull barrel 6x45 with an Olympic SUM (stainless Ultra-match broad cut barrel)
Bullets wise I have been shooting Sierra 90 grain GameKing #1535 BTHP as well as the Remington Bulk pack 80 grain SP. I don't shoot bigger than this in my 6x45 due to the 1:10 twist. With your 8 twist the Hornady 87 grain SP should work well too. (I like Hornady bullets for hunting and targets, I use the 100 grain interlock exclusively for hunting in my 243 Win)

I mainly use my 6x45 for yotes but I have been toying with the idea of antelope as I guide hunters and want to use something different. I would use the Remington 80 grain bullets for speed goats without hesitation as they have a proven track record as a game taker and my rifle shoots very well with them. Not up to the 60 grain for accuracy, but well enough for hunting.

Well, as luck would have it the Warehouse didn't stock the 90 grain Gamekings. They did have an 85 grain Gameking so I got a box of those. I also picked up a box of Nosler partitions also in 85 grain. My plan will be to work up some loads with H 335 and see if I can get them to group.

Ok, well I 've had the loads ready in H335 to go to the range...so maybe I should work some up with Varget and some other powders, since it will probably be June before this wind dies down.
