IS it going to be the 30-30 vs 35 remngton. A bit more bullet, but no more powder...... Couldn't zoom in on the box too well, looked like 2150 fps on the back of the box at 0 yards. IT not really based on the 6.8 spc, but has the same base. Might be available in AR rifles though, which makes it interesting for me. But my state villianizes AR's, so a mute point for me.
I'm in NC vacationing during this lovely tropical storm. Went to sportsmen warehouse looking for ammo. MY 325gr 215fps 450 marlin, they don't sell ammo for it. Same with a local mom-n-pop place over there, no 450 marlin. Got a full 50 cal box of it, but NY changed a law, in their parks non-lead. So, I'm hunting for copper solid ammo. Need to get 44 mag bulet heads too, my modern inline T/C omega like 240gr hornady XTP's. Be nice to find something similar in non-lead.
IF you buy it, get 10 boxes and don't tuch that pile.
The other thing, there is little like it around in 40 cal. Handgun bullet heads will likely expand too much, maybe even the rifling will be too aggressive on thin and soft handgun bullet heads in some cases. Hopefully, the gun you purchase likes the bullet and how it's loaded. Might be awhile before dies and other suitable bullet heads become available. I work in engineering, so I don't like anything new. Like for something to be out for a few years, so they get the bugs out of it. Although, guns n ammo are relatively simple compared to other things.
2150 fps 215 grain should be a good deer gun to 200 yards easily.. Winchester's website boasting didn't include velocity or range.
