H 4350 has worked good for 22-250 (50 grain),257 Wby (75-80 grain bullets)300 Wby (130 grain),and 375 Ruger,(300 grain).Nice to buy 8 lbs and save some money as well as not having  to worry about working back up your loads with a new batch of powder.What others have you found that work for different calibers?Roger

IMR 4350   30-06 150 gr. Nosler Accubond @ 3000 Fps.
7mm Rem. Mag. 140 gr. Nosler Accubond or solid base B.T.@ 3282 Fps.Mark

I have used IMR 4350 in  the 6mm Rem, 7 Rem Mag, 270 Win, 270 WSM  7mm-08,and even 308.  I have used H4831 in most of these too except for the 308. I use BLC-2 in the 222 Rem Mag, 223 and 308.  It would probably work ok in the 7-08 never tried it.
IMR 4350 is my fav for multiple rifle rounds since it works well in the rifles I shoot a lot.
 
 

IMR 4350 for my 30-06 and 7mm.  I am going to try it on a new 243 also and see how it fares.

IMR 4350 works really nice in a 243 win.

Well, I've used IMR7828 and Accurate MagPro in my 270Wby, 300Wby, 243Win, and 7mmRemMag with good success.

H4350 has been useful in my 30-06, as well as limited use in my 8x57.

IMR and H4895 have proven useful in my 30-30WCF, 8x57, and 243Win.

I've likely got some other "group powders" but I can't think of them right now.  I can say I'm working toward consolidating to the H powders where I can, as I get consistent velocities and groups from them in several of my rifles.I believe this is a practical world, and in it I can count only on what I can earn.  Therefore I believe in work, hard work. - The Auburn Creed

I just recently bought an 8 lb container of IMR 4350.

IMR 4831: My brother I use it for the 25-06 Rem, 270 Win, 264 Win Mag, 7mm Rem Mag. Haven't run any loads over a chrono yet, that's tomorrow, but I've noticed accuracy to be the best to date.

IMR 7828  300 & 340 Weatherby Magnums its one of  the fastest and most accurate powders in the Nosler # 5 book for both.Mark

RL 25:

257 Weatherby
270 Weatherby
300 Weatherby
Some 340 Weatherby loads
7mm STW
300 RUM
338 Imperial Magnum

Yes, it works well in all those cartridges. I slightly prefer RL 22 in my 270 Weatherby for accuracy. You'd better believe I but it by the big jug.

H4350 second most versatile:

270 Winchester
30-06
300 SAUM
7mm-08
375 Weatherby
Some 243 loads

That's my $.02 anyway

Buy it by the big jug. Sorry.
