"The .357 isn't enough for deer and isn't legal for deer in most places."
Hmmm....
From the Buffalo Bore webpage:
18.5 inch Marlin 1894
170gr. JHC (jacketed hollow cavity) = 1860 fps
From the Winchester webpage:
30-30 Winchester (barrel length not specified, but I'll bet it's longer than 18.5")
170 gr. Super-X® Power-Point = 2200 fps
So, comparing 170 grain bullets, the .357 Buffalo Bore is only 340 fps slower than the .30/30 at the muzzle. If we accept the premise that the .30/30 is okay for deer (hard to argue against that!), then it seems to follow that that the only slightly slower .357 should also be enough for deer.
I have a Winchester 94AE .357 Trapper that I consistently get 2 MOA at 100 yds shooting Remington 180 grain semi-jacketed hollow points, which are reported to reach 1590 fps from a 20" barrel.
Shot placement!
I've lightened up the 94's trigger a bit, and polished up the internal parts. It's not a target rifle by any means, but is fine for hunting. I'll be using it for deer for the first time this year under Indiana's new law that finally allows rifles in pistol-class cartridges to be used. My alternative is a .50 cal Omega, which has similar ballistics (i,e., the rainbow trajectory as the .357), and which I use during the muzzleloader season.
The 180 grain Remington ammo is about $35 per 50, and I can practice with ammo that is less than half that price.
Food for thought.
