Can someone with a load data account please check to see if there are any.. 7mag 150 gr and/or 8mag 180 gr loads listed for the RL 17 powder,I cant find anyhting I can tust anywhere on the net,THANX!gun)

You'll find some data for the 7mm RM in this article... Alliant Reloder 17 Have you tried Retumbo for those cartridges? I believe RL17 is more suited for short mags and such.

Re: Load data HELP! I ran Quickload to see what it had to say and RL 17 didn't make the cut for the 7 mag. These are all the powders that came up.

It starts at about 72g and goes to a max of 77g. Good luck.

Thanx Storm,the 7mag is listed on the link above but for some reason they butchered the 150 gr load data,did they give a max FPS on the 8 mag load?gun)

Re: Load data HELP! Quickload came up with 74.1g of RL17 for the 180 TSX at 58403 psi (max is 66717 psi) and a velocity of 3079 f/s with a 24 inch barrel. If I ran the max psi it shows a velocity of 3195 f/s at pressure of 66554 psi.

Check the Nosler site they have a good starting loads data sheet for the 7mag. I allways had good luck with the H 4831 for 1000 yrd matches . 65.5 grs of H4831 with a 168gr SMK @ 3152 ft/sec was my most accurate load (Hot but not to hot). And now with H4831sc it is easer to measure. J E CUSTOM

Nonya, if and when you get a good RL17 load worked out for the 7RM, please let us how it does. Thanks, -MR
