Getting my reloading gear setup, mounted press today, need a couple of items, tools , dies and trimmer. I want to order my components soon, figured out most calibers except 243. I will probably go Nosler 95-100 bullets because of good past experence(20 yr) now powder I can't remember what I used. Any recomendations on a brand/type of powder to use for deer hunting? Also want it to shoot sub MOA of course. Thanks Roscoe ps The gun is a Sauer 202 and not sure of twist, about 22" barrel

I shoot 85 gr and 95 gr Sierra in my .243 win. The powder I'm using is H-4350.
Make sure your rifle has the twist to handle bullets heavier than 100 gr.
 
H4350 and H4831 are 2 great powders for 100gr bullets.
I personally prefer H4350 because it flows better in a powder measure
Many shooters competitive shooters get more velocity and accuracy with H4831.

I find 760 for the lighter bullets and the 4350's with 85gr and heavier. I have not had a lot of luck with 100gr bullets in my BLR but work well in the model 70's.

I don't reload 243 but I use IMR4895 in 308 and 22 250 and it works wonderful in both so it should work great in 243 as well.

4895 is too fast a burning powder for any of the heavier bullets in 243.
4831 is real good for 100 grain.
 
I have found IMR 4350 to be a very accurate and consistent performer in 243 and also gives some of the best velocities attainable, some of the newer RL powders show promise as well. I believe someone said RL22, but I would think it a bit slow for optimum performance, maybe RL 19.

That is beauty rifle you have there, I can remember when P&D had them on sale for $1400 a number of years ago. I was asking the same question on some forums in the USA not that long ago, accurate reloading . com and most fellows seem to like IMR 4350 for heavier bullets. I did some loads with the Sierra 70gr matchkings with Win 760 a couple of months ago and they shot very well in my sako Hb. I have some 58gr Vmax loads that I may shoot tomorrow loaded with 4350 as it is the recommended powder in my Lyman manual for this bullet. FS
 
H4350, IMR 4350, H4831, IMR 4831, N-MRP, N-204, RL 19, RL 22, Vihtavuori N160, N165, IMR 7828 all work well in the 243 with 100 grain pills.
Just a matter of what you rifle works best with.

Been using IMR4350 with 90 and 105 grain bullets for eons. As good a place as any to start.
"...has the twist..." Not much of an issue. Most commercial hunting rifles, even heavy barreled varmint rifles, are rifled for deer weight bullets. 85 grains and up. Usually not a big deal anyway. Some rifles do prefer heavy or light bullets though. Some shoot either well. In any case, if you're using the rifle for varmints only, there's no reason not to use heavy bullets. A ground hog, etc. won't care what kills it. Varmint bullets, usually under 85 grains, are not suitable for deer sized game. They expand rapidly without much penetration upon impact. Deer bullets penetrate while expanding.
