7mag load help

i have a rem 700 7mag with Jlock on it. i am trying to find a load for the gun with 120 TSX. i know, you guys are going to say go 140 with the higher BC, but the farthest i will ever shoot is MAYBE 500 yards. i have ben having trouble getting it to shoot with the smallest group around 1-1 1/4 inches. i have loaded it with H4350 and H4831sc win brass and f215m primers. i have on hand some R22 and f210 primers, should i look more at changing powders or lenghts? does anyone have a load that shoots well out of there 7mag? i am looking at under 1 inch at 100 with the gun.
Casey

I won't tell you to go w/the 140 gr. I'll tell you to go w/the 160 gr [img]/ubbthreads/images/graemlins/grin.gif[/img]!

One thing to keep in mind is the fact that the rifle was not designed to shoot this lite of a bullet. I'd bet you get better accuracy out of the heavier bullets.

Don't have any loads, but the 140 is PLENTY for a 500 yard kill. Also, if it is factory, the rifle probably is twisted for the lighter bullets.

Re: 7mag load help

You may want to get rid of the Jlock firing pin assembly. I did and it did wonders for my trigger pull. You may also see an improvement in accuracy as well. Here's the one I used.

I had good luck with IMR 4350 and the 140 gr ballistic tip in my 7mag. Hope you can find a bullet that shoots! [img]/ubbthreads/images/graemlins/grin.gif[/img]

Re: 7mag load help

FCW80,
I tried some 120gr Sierra Spitzer in my 7mag Sendero back in Oct 2000. Didn't have a chrono at the time but the load data was 58gr of IMR 4320 using a Rem case and CCI BR2 primers. Accuracy ran .4015" for 3-shot groups @ 100yds. I did shoot them for groups at 500yds - ONCE. The wind blew them (120's) all over the board. I don't think I've shot them anymore.
I think you should look at replacing the j-lock bolt shroud assembly. Take that bolt apart and look how convuluted your firing pin spring is. Compare that to a non j-lock bolt. JohnnyK.
