Trying to find load info for the best range of powders for my 7mm SAUM especially RL 17 with the 120 gr Nosler BT & Barnes TTSX. If anyone can assist it would be greatly appreciated. I am not familiar with Quickload so please PM me for the parameters needed to run the search for me. Thanks upfront for any assistance

Thanks for the info. I was looking specifically for RL 17 data but its just not available. I am going to do some projections and work up using the chronograph.

I know you've said you want to use R17, but H4350 works great in this appliction as well. I've using it w/ molied 120 TSX to get 3350. They don't bouce off!

I have 120 BT's load with H 4350 to try after Thanksgiving. I just ran a series with Ramshot Hunter & 120 BT's with good results.

3300 fps, 2900 ft/lbs of energy at around 55,000 psi looks like some serious juju with good barrel life in the SAUM case.

Yes the desk top ballistics is what brought me to the cartridge. The groups I have gotten so far and the on game performance on deer and hogs with just the 120 gr. BT's & Barnes TTSX has been tremendous. I am looking forward to going across the bullet weight spectrum with this cartridge the remainder of winter and this coming spring. 140's are on deck after I finish trying H-4350 & RL 17 with the 120's. The groups I got with Ramshot Hunter & 120's will be hard to beat.
