Re: 7mm STW Reloading Thread

My gun is a Remington 700 w/a trued action, 27 1/2" number 3 fluted PacNor barrel, 1-8" twist, with a Defensive Edge muzzlebreak, sitting in a Manners Hi Tech stock bedded and pillared, Jewell trigger set at 1.5lbs, scope is a Leupold LR 4.5-14 VX3 with M1 target turrets. My best load is 72.5gr. of Reloader 22, Fed115 primers, Remington 7mmSTW cases, shooting 180gr. Bergers right at 3100fps. My COAL is 3.68 and thats jumping the lands 120 thousandths. My three shot groups average .250-.368" at 100yds. I normally get 5-6 reloads out of these cases. This is my lightweight long range gun. I also have a 300RUM and a 338Edge.

Have read and heard that guys using 8mm Mag cases are getting more reloads out of their cases as the webbing at the bottom of the cases are thicker. Anybody know if this is true? Have never used anything but Remington 7mmSTW cases but being hard to find I'm looking at making a change. Those in the know, what are the pros and cons of going this route? Thanks guys.

Re: 7mm STW Reloading Thread

One of my STWs has a lands at 3.99 but it's a win model 70 sobox is 3.61 or so. Still working on load but need to make sure it fits in mag.
I'll try rl22 see if I get better results

Hey ButterBean, just curious here. How much bullet jump is too much? I ask because my STW's freebore is 3.829. To seat the bullet to work with my magazine, it would have almost a quarter inch jump. I know I'm losing a lot of velocity seating it back that far and had decided not to use the magazine as a sacrifice for better accuracy until I read your post. I had never heard that before.

NC just seat it to mag length and dont worry about it ...I know it seems like alot of jump but its no big deal ...What kind of rig are you shooting?

Remington 700 action, custom barrel (unknown twist), HS Precision stock, Timney Trigger, Leupold 4.5-14x40 scope on a DNZ mount. Can't seem to find anything it likes to digest consistently. I've tried RL 22 and H1000 with Nosler CTBT in 140 and 150gn. Just got some RL 25 and some N165 to try now. The barrel will probably be shot out before I ever figure out what it likes
