7mm SAW

[st1650]

I tried H4350, which is what everyone, including WTO, recommends. But I just didn't get the speed I wanted. I'm getting 100+ more FPS from the StaBall. And still getting good ES/SD numbers, as well.

I was getting more speed out of varget than 4350 by about 50-75fps

What was your load?

What was your load?

Initially 42.6gr varget, 2.935in 162 eld-m, 2775 fps out of a 22in tube then it sped up so I lowered it to 42.3gr. It was my most accurate load.

Then last year I worked up a load with the 145lrx because I wanted to try monos for short range hunting and limit the lead in the meat. Worked great on the bear I shot last fall. DRT.

With the 145LRX
42.5gr varget. 2.880in 145 LRX, 2875 fps.

All Alpha brass SRP.

By comparison, my 162 Staball loads give me 2825FPS but that’s at 49.5.gr. Very hot load. Probably 65-70K psi

If you have any of that load pressure software (can't remember the name of it at the moment) what would it say max load for a 175 Elite would be, seated to 2.235" to ogive?

I use the same Alpha SRP brass, and use CCI 400's

Out of my 20" barrels, 48.0 gr StaBall 6.5 with the 175's was getting me ~2,760(ish)...
