RD's 357 Mag Bullets
Posted: 02 Nov 2012 19:23
Thought I would show you my three bullets that I'm shooting or will be shooting through my two R92s chambered in 357 Mag.
The bullet on the left, my TLC356-135-RF, was actually designed as a +P bullet for the 9mm Luger. The designation diameter, "356", is a little misleading in that it has a .356" bore rider nose. The bullet body's greater diameter is .357", a perfect fit for the R92s .355" groove. It just happens that the nose works out well for the 357 Mag, at a cartridge OAL of 1.59" the crimp groove lines up with the case neck for a perfect crimp. This bullet is under diameter for large diameter throat of my Marlin 1894C.
The middle bullet is the bullet I designed for the 357 Mag, my TLC359-175-RF. It is a 175-grain bullet. The bullet on the right, my 190-grain TLC359-190-RF was designed for the 35 Remington. By using 38 Spl brass with this bullet, the crimp groove matches the case mouth perfectly at 1.59". The short case also helps with the issue of cast bullet case bulge and I shoot the cartridge at 357 Mag pressures.
All the bullets are gas checked and sized .357". I use Lil'' Gun with all of them. 19.0-grains for the "135" produces 2100 FPS. 16.0-grains for the"175" at 1800 FPS. 15.0-grains for the "190" at 1700 FPS. I'm using the "135" and "175" in my Skinner Peep sighted 56-001 rifle and the shooting has just started with the "190" in my new "56-002" scout.
