Slowest STW known to man
Goodness graceous, I have the slowest 7mm STW known to man. I shot my 7828 load tonight 74gr with 160gr with avg. velocity 2900fps. Its out of a Sako 75 with 26" barrel. I have shot H1000 with ok accuracy but not what I was looking for. Thinking of RL25. I also have RL22, H4831sc and Retumbo to try.

Yeah it wasnt a pretty day at the range with bigcountry......especially when my 7 rem mag out shot his 7 STW by 200 fps. He was moanin the whole time......"I got the slowest 7STW on the planet". The real kicker was when I brought out my 7mm-08 and shot a 160gr at 3100, he was ready to jump off a cliff!

I guess were gonna have to get ol' stubblejumper down here from Canada and show him how to load the STW up to get 3400 fps like he says he does

Give slower burning powders a try with that 26" barrel. IMR7928 is a little fast for a large capacity cartridge like that.
The last rifle I built for myself is a 700 in 280 Rem. I went with a 26" barrel for some silly reason. Every load I shot through it was way slower than the maunals said. I finally figured that since I was using a 26" barrel that maybe chamber pressure was dropping off while the bullet was still in the bore. So, I started experimenting with powders that were slower than listed loads. It worked. Now I get the velocity without the hot loads.
I also go the other direction with my XP100 pistols in 308 Win and 243 Win. Both have 17" barrels, so to get the velocity I want, I started with the fastest powders listed, then went off the chart to even faster powders. My deer load with the 308 is a Barnes 150 gr TSX with RL12 and it's moving at just under 2700 fps. Elk load is a 165 gr TSX, RL15 at 2550 fps.Pretty fast for a handgun.
Long story short, get a burn rate chart, and experiment....Safely!

man I just remembered this, you guys wanna really get bigcountry frazzled, ask him about his .308 and a certain collet die
bigcountry: "I spent 3 days loading those suckers"
mossy: "Whudya do that for?"
