What about the Ramshot Hunter
, and (hodgdon) Superformance
I shoot a 338WM in S.C. at 500' Ele., 90 to 100 Deg, H4350, Barnes MRX & TTSX 225s and no problem in CO at 9,000' in -10 deg.
I bought some Hunter because Barnes listed it in tests. Never loaded it yet. Know any good or bad on Hunter (what load)????
Also, just found out Nellie LOVES dirty barrel 'GMX 185 Superformance' ammo and it don't kick as much as 225gr pills (NO BRAKE)..
Any knowledge or rumors on Superformance with 9,500' & 100 degree temp swing for my Nov. ELK hunt in CO. this year???? We alreday proved that current 185 GMX setup on my Zeiss should hit 7 to 8 ins high on 500-600-700 & 800 yd "PINS". I don't know what to expect from the powder yet!!!!
Help please if you know or have heard anything ref. Superformance sensitive to temperature .
Added later......put another way, my 7"up + richard's 6" down = 1 " up....?????? Thats, about as valuable Info. as Ron White (AKA TATER) knowing how many bouncers were going to kick his A$$E! I NEEEEEDDDEEESSS to NO!
Powders and MV change in cold temps

If I develop my loads at 98F and then go hunting at 32F, I can plug all that data into my software. But, I noticed it doesn't adjust MV according to the temp that I input although it will adjust trajectory according to what you tell it about the air temp/altitude/pressure.
As such, there could easily be another 6" additional drop at 600yds due to 100 fps lower MV.
My point is that you shouldn't assume the software knows anything about the temp stability of your powder.
Hence, you should shoot your rifle in the conditions you will hunt and take copious notes for future reference.
