Buffalo bore makes a Heavy 357Mag load in 158grn HP that they claim runs 2,153fps in an 18.5" long Marlin levergun! Using Handloads.com's free Ballistic Calculator and inputting .357 caliber, 158grn, and selecting HP you can calculate the Bullet's BC of 155. Then at the right, if you input 2,153 velocity, set the sight-in range at 100, the ...
Trajectories are very close. Recoil is much more stout for the .44. Accuracy for both is about the quality of the rifle, not the cartrige. Both are capable of excellent accuracy if used in a well built scoped rifle. The .357 is much cheaper to shoot and .38 ammo is even cheaper for varmints or target practice.
The 357 Magnums advantages in a carbine are 1) more case capacity 2) slower powders 3) higher velocity 4) Higher sectional density bullets for deeper penetration 5) Higher ballistic coefficient bullets that retain more energy downrange 6) flatter shooting. The 10mm has 1) a fatter bullet. Reply Like. 2.
I second the post about Marshall's cast bullets. I load a 185g bullet to 1725 fps using lilgun. This is 30-30 ballistics out to around 100 yards. I've shot this from a smith snub for a function test, but the main platform is a win94 trapper. OTOH, that trapper loves white box 125g loads and drops 100 meter rams with 158s. Very versatile rifle ...
If the '73 in .45 colt is limited to cowboy loads, I might go for the .357 mag. I've owned lever action rifles/carbines in: .25-20 (Marlin 1894) .357 (Rossi Puma), .44 Magnum (Winchester M-94), and still have my Rossi Puma in .44-40. All are great with the .44 Magnum producing a nasty recoil, but accurate.
A standard 30/30 load will generate between 10.5 and 12.5 pounds of recoil, whereas standard 357 mag loads (from a carbine) will generate about 4.5 pounds of recoil. If your shoulder cannot discern the difference between those two, then the really big magnum stuff must be a breeze! Rifle Recoil Table.
23 posts · Joined 2005. #1 · Nov 25, 2009. I'm working up some hunting loads for my Pedersoli Baby Rolling Block .357 mag rifle. Components; 180 gr gas checked Cast Performance Bullets. H110. Federal small pistol primers. Winchester cases. FIRM roll crimp from a Lee Factory Roll Crimp die.
I had a load for a 158gr Speer Lead RN/4.0gr of Red Dot, that worked well in my 77/357. It was slower than a .22LR subsonic, judging from drop over 100yds, sighted in at 50yds. It never left a bullet in the bore, and leading was minimal. My guess is that Bullseye, Green Dot, AA N0.2, or similar would be worth trying.
S&W 4" Mountain Gun model 29-8 w/230 gr. .44 magnums and generally a Ruger GP100 6" .357 magnum. I'm more accurate with the .357's, so the .44 is for closer and larger critters. I like revolvers, but I recently got me a Marlin 1894ss lever action rifle in .44 magnum, too, to go along with the mountain gun.
