85 TSX @ 2800 from 6mm ARC would offer 1490 ft lb at muzzle, 469 ft lb at 500 yds, 64.3" drop, 31.8" of drift (10 mph, full value)I was talking an 85 TSX in 6mm ARC
Not a direct comparison because mine's a 19" barrel and 243 LBC, but the 90gr TGK does 3050 fps, and the 90gr ELDx will do a little under 3,000.For the sake of discussion on velocity, I get 2900fps exactly using a Proof Carbon Barrel with 90g Gold Dots and factory ammo out of my 6.8. I'm 3.7mils to 500 yards and 264ftlbs of energy. Anyone have comparable data for their 6 ARC w/ 18" barrel at 500 yards? @MSTN
Once my 6.8 Stock is gone, most nearly going with a 6 ARC.
I’m still waiting for my Odin barrel (no ETA yet, frustrating) but am hoping that by the time I get it and build the rifle someone will be loading the Barnes TSX, TTSX or LRX bullets in 6ARC.85 TSX would make a wicked killing bullet for thermal hunting, hence my question.
I’m a bigger for caliber bullet kinda guy in general, there are exceptions to rule thought.
Over 29 of N-540 and you'll most likely be over pressure based off what I've seen in a Bartlien bbl, 6mm AR and ARC is slightly less capacity.Has anyone worked up a 6ARC load with VV N540?
I found a pound of it in my powder inventory and know its a good powder for 6.5G. Looking to try 30.0grs of the stuff with the 105gr Berger at 2.25". But if anyone has any intel, it would be appreciated.
Sounds pretty much right on with what I've seen for the same bullet. My favorite shooting spot is 615yds across a canyon at 6,000' da, which takes 3.7 mils. While I can't verify 500 yards at that point (since it's out in open air ) it works out to 2.6 mils and 1,000 ft-lb, but my load starts off 50 fps faster too, so I think those numbers correlate really well with yours.When I give you these numbers, keep in mind I’m operating at a 7000’ density altitude.
With the Hornady 105 BTHP at 2689 fps, at 500 yards, 2.7 mils and 977 FT LB of energy.
