Home Forums Reloading Big Game Rifles The most temperature stable 358 Winchester powder?

I found 8lbs of Ramshot Tac, it's nice that I can use it in the 7mm-08, 308, 338 Federal and the 358 Winchester.

Now to see if I can find some of the other powders listed.

If y'all have some beginning loads with the following bullets

Hornady 200gr Flex Tip #35105
Hornady 200gr Round Nose Interlock #3515
Sierra 225gr Spitzer Boat Tail #2850

I have some Nosler Accubonds, but I don't think I am going to use them in the bolt guns.

Thanks again for any information, Darryle

I have added almost a thousand Hornady 200gr bullets, both the Interlock and the round nose. The round nose I am hopeful will work well in my AR for smacking pigs when combined with thermal.

I also found an 8lb jug of H4895, hoping to find some H4350 and H4198 for this and other projects, mainly the 7mm-08 and 270 WSM.

Again, I appreciate the advice, insight and real world experience, means a lot to me.

For the 358/200 I wouldn't pass up IMR3031 or AA 2015 if you can find some. Both work nicely in all 358s I've ever owned. AA 2015 works with 225s as well.

Thanks for this information, I really appreciate it.

Thanks Darryle

TAC in mine with Barnes 180 ttsx. She really brings it with a 16" barrel and a metal buttplate.

TAC and H4895

Tac is supposed to be good but I have used 4-64 and Varget for a lot of years. Never had problems with either one. Be Well, RZ.

Don't know, do know with RL-10 I can push 200gr TTSX's to a bughole accurate 2700 fps in my Ruger stainless/syn Hawkeye, with what I consider a max 350 yard hunting rifle/cartridge, I can't hold the difference in field hunting conditions to worry about 50 fps plus or minus.

I too use a fairly stout load of TAC and 225 gr sgk's in my 358 Win. I shoot (practice) during the spring into late summer here in OK and I know several days were in the lower 90's. I've hunted with it last last couple of years in S. Dakota during some really cold weather (down to 2 degrees one morning). I've never noticed any problem related to pressure at either extremes. I'm sure it may have lost some velocity in the colder weather but not enough that affected my shot on a smaller mulie buck, but the shot was just under 160 yards.
