These loads may work for some shooters but I'd suggest looking for a more modest velocity
I must be one of those guys then.....Only I don't wonder if the pressure is to high. I get 3360 fps out of a 28" broughton with the 168 bergers. So far the cases have been reloaded 7 times. There is no pressure, the bolt opens like there isn't even a case in it. Accuracy is very good, typical groups at 100 are in the .4's if I do my part. It might be the barrel though, this rifle doesn't seem to be very finicky. I didn't start to see pressure or a sticky bolt until around 3425, which is about 2 grains more powder. I did have a reamer made with a tight chamber and be able to touch the lands, while using the Wyatts box magazine. My Dad's rifle does 3320fps with a 27.5" Lilja barrel with the same load. ES and SD are both very low in these rifles.
So far, I have around 500 rounds through this rife ( we built it the end of Feb 07), and it is still shooting great. I have taken prairie dogs at just over 1100 yds with it. Hopefully the end of the month, she will get her turn at a deer or elk in Montana.
I originally started with H1000 and velocity were averaging 3297 with single digit es for 10 shots. It was a good load. Then Dad tried some RE-22 and found that he got more velocity. So, this week I have been testing RE-22 and finding that I still get the accuracy, low es and sd, and get another 70 fps. Well, the fact that I ran out of H1000 didn't help either.
The 7mm STW if a great round. I also have a 7mm Allen Mag. It seems to be a little more finicky, but once you find what she likes, its awesome.
