- consistent lot to lot
- Less than 1fps per degree temp stable
- Fast: with 208 A-Max my 'hot' load is 2887fps, slow load is 2720.
- Consistent shot to shot, using my Magnetospeed chron, 5 shot strings: SD=4 for that hot load. The slower load SD=3
- Accurate: Sub-Moa out to 700yards, that's the farthest I have at the moment. 100yards does not mean much with this big bullet. My zero is 300 with 1.125 group recorded. I've improved my shooting since then.
I have 400 down the pipe, a 28" Pac-Nor sendaro.
IMR-4350 is not a good substitute for me. acceptable but not preferred.
I have tried RL17, RL19, RL22, IMR. Nothing works as well as H4350 for me. That is the same for my 260 Rem as well.
I am trying H1000 and H4831 so that I can stretch my H4350.
H1000 is only for heavies. Fast without pressure but max case capacity gets an SD=4 at 2745fps.
WAIT - I shouldn't be telling you this. It's hard enough to find H4350.
