Re: New 7mm stw shooter, need reloading data

Got a customer using 81 gr of reloader 22 with a 150 barnes ttsx. Its going 3600 fps and grouped under 2" at 600 yards off the bipod. It was a pretty hot load but it shot great and was a laser, start off with a lot less powder. It did good on deer if you hit em in the high shoulder. He said if they were hit behind the shoulder it took awhile for them to expire because the bullet didn't expand at all.

A bit harsh on the charge weights.... That load wouldn't go anywhere NEAR my rifle.

Ya it is a pretty hot load. He only shoots that gun during the late doe season in Iowa. Its usually pretty cold that time of year, January. It was cold enough when he was load testing that he had to switch to magnum primers, little bit of hangfires with regular primers. I think he might of backed it down to 80.5 which is still around 3550 fps. Im just wondering how long his barrel will last.

His pipe won't last that long at that pressure. He's got to be between 75 and 80 kpsi at that speed with that powder and bullet. I wouldn't even want to touch that pipe for a re-barrel if he's been running that stuff through it; the dang action will likely have issues like stress cracks. I'm surprised some moniker like "hot tamale" hasn't been mentioned yet......Heck, the 7rum won't run within 150 fps of that in a 26" bbl; he's ~250 fps hot of a safe load.

He said at 81 gr it was sticky bolt lift. So he backed it down to 80.5 and it was easy again. Primers looked fine. 29" Brux barrel. And at under 2" at 600 yds it doesnt shoot bad either.

I heard that Reloader 22 burns kinda dirty compared to H1000 or Retumbo or even Reloader 25.
Any thoughts?
