Why is it that any published load data for the 7STW does not show much more velocity than a 7Rem Mag, even though there is more case capacity with the 7STW ? I would like to load 168gr Bergers to about 3200+ fps with my 7STW. Does anyone here reload for this cartridge ?
I have some loads from an older book that are much hotter than newer loads. It is before it was a regulated cartridge by SAAMI so it didn't have pressure restrictions.
I'll get them sometime when I have access to my desktop. (on a laptop now)
Love shooting precision and long range. Big bores too!

I have been relaoding the 7 stw for over 10 years now and you can get up to 200 better FPS than the rem. The keys are to use a very slooow powder. I have tried most of the slow ones and H870 or AA8700 does a very good job. The second thing goes against what most people buy the STW for, that is heavier bullets. I have loaded everything from 120 grains to 175 grains. Most people shoot the 140 grain bullet. I have found that I get the most gain over the 7MM Remington by using 165-175 grain bullets with the very slow powders.
I load a 7mm Dakota & the case caps are very close. In my 26"bbl #1, I easily run 160grNPs a 3200 using IMR7828. I imagine RL25 would also work well. I have tried AA8700, but find it almost too slow for best vel.
