Re: 243 with 115 dtac loads

I shoot the same load through my Scalpel and Nighthawk in 243. The Scalpel has a 26" krieger. The nighthawk has a 26" Broughton. They both shoot this load:
Lapua Case
47.2 grains of H-1000 with a pointed DTAC at 2.77, Fed 210.
You can also try bumping that up to 47.5 for a little more speed.
Or use, RL-25 at the same rate, but I pefer the Temperature insensitivity of the H-1000.
Hope it helps

That'll get you in the ball park. I'm using Lapua brass filled up with 47.5gr of H1000 @ 2.83" OAL out of a 27" Krieger.

27" Kreiger 7.5 twist barrel, 42.5grns of H4350 in Win brass with BN coated 115 DTAC gives me 3020fps.

Re: 243 with 115 dtac loads

I would suggest starting at 38.5gr of H4350 and working up in 0.5gr increments until you hit pressure, then start accuracy testing.

I did a work-up with H4350, but in my rifle the pressure peaked a little earlier than I wanted. Others have had better results. No telling till you try it and see.

Good Luck!

Re: 243 with 115 dtac loads

I was able to get up to 42.0gr of H4350 with a speed of 2975, but the pressure was higher than I'd like. I was getting quite a bit of flow into the ejector plunger at that charge weight accompanied by sticky bolt lift. When I switched to H1000 I was able to achieve that same velocity and then some, but I backed off the charge weight to the most accurate load.
