I am looking for load data for my 7mm Rem Mag and a 140 gr TTSX bullet. I have RL25, H4831SC and H4350 on my shelf. I've used RL22 in this rifle in the past but don't care for it that much. The rifle is a Win M70 with a 26" barrel....
I have a load using RL-25. 140gr ttsx 69.5gr RL-25 win mag primer ,3120FPS in a rem 26" barrel . cant tell you the seating depth ain't got it written down in note it is in the box label and son has gun and loads right now.
65.5-66.0g of IMR 4350, Rem brass, Rem 9 1/2 primer, bullet seated .050 off the lands=1/2" groups out of one Rem 700.

I shoot another load of 67.0g of R#19 in a win case with a fed 215 primer with the 140g TTSX seated 0.050 off the lands.

Both of these loads are safe in my rifle, work up to these loads in your rifle, and they are both a tad over 3200 fps in my rifle.
For what powders you have on hand, I'd start with H4831 at 67, 68, and 69g to see what shot best.
I'm awfully fond of IMR4831 in the 7mm Rem Mag. With 140 gr bullets, I've also used H4831 (war surplus) and IMR4350 in Remington 700, Sako L61R, and Browning A-Bolt rifles.

My current fave load with the 140 TTSX is 67/IMR4831 for 3214 fps out of a Remington 700 SS with a 24" barrel. Cases are R-P and the primer is the Federal Magnum. With this recipe, I've taken my best whitetail, my 2nd and 3rd best mulies, and my only Roosevelt elk. In 2 weeks, I'll be chasing a tule elk with the same outfit.
Thanks for the info. I am loading up some test loads with H4350 and H4831 to try this weekend or next. I'll report back. I am seating the bullets at .050" off the lands.
