Home Forums Hunting & Shooting Long Range Hunting 7mm STW

Yoder409,

I asked myself the same question regarding the performance of the STW and RUM from a 26" barrel. Took two rem 7 mag takeoffs and rechambered them. The 7 RUM beat the 7 STW by 50 fps using RL-22 and a 140 nos bt. IMO the 7 RUM needs at least a 28" or longer tube or you might as well stay with a STW.

I am looking at the big 7s myself.I think that I need to start a 7mm mashburn vs. stw thread.

Imagine what a great round you'd have if you necked a 7mm STW up to 8mm.

Might as well weigh in here...

I've had a 7RUM. I still have a 7STW....

Shooting 160's in both, the 7RUM got about 100fps more mv.....3300 with the 7RUM vs 3200 with the 7STW. That is without leaning on either.

Was very accurate, easy to load for...was a hungry SOB though.

To be honest, for the extra 100FPS with a 160, I didn't think it was worth the extra recoil and powder, so I tripped it.

For me, the 7RUM was more of a play toy thing, never hunted with it.

I suspect shooting 168 or 180 Bergers would make the 7RUM really shine. Like shooting 160s out of the 7STW gives it a big advantage over the 7mag.

Nothing wrong with the 7RUM. Since I had already had an 7STW, it became expendable.

I have loaded for both, still prefer the rum even with 160s, not by a wide margin. Now if lapua would just make some brass for it.

Thank you !!! Answers my question to a T .

BTW....... did you ever experience any temperature sensitivity with the R-22 ?? I developed and loaded a batch of 120 SMK's in the fall a couple years back. They shot very well. The following summer they were COMPLETELY off the wall..... blowing primers, nearly locking the bolt up.....

....... and Winchester would re-run their STW brass.........even if only seasonally

Anyone try Nosler 7 STW brass? I perfer W/W over R/P easy.
