I am of the opinion that in the world of taking game silently, a big, fat 400-500 grain .45 caliber projectile would solve so many problems associated with sub-sonic bullets of .30 cal and below. I've been reading about how difficult it is to get reliable performance from sub-sonic 300 Whisper cast bullets on game. The problem being, small meplat. But, you're limited by how big a meplat you can have that will still function reliably in a mag fed platform. Even if you take away the mag and have a bolt action 300 Whisper, the b.c. of a sub-sonic 210-250 grain bullet with a significant meplat isn't very good, with energy diminishing drastically within 100 yards. With states that have the 1000 ft/lb energy laws, this is an issue
At sub-sonic velocities, in order to achieve desired performance what you need is mass & meplat! Why settle for a mag fed semi spitting 210-250 grainers, when you could have a lever action repeater lobbin' 400-500 grainers?! My hypothesis is, given how well 250 grain Keith's and 270-SAA's perform without question at sub-sonic speeds out of a .45 Colt, I'm sure the 45-70 cartridge topped with nearly twice the lead would be unrivaled in the sub-sonic terminal ballistics arena. With a lever action, the meplat problem is solved, leaving us only to deal with carrying energy down range. That's wear mass in the order of 400+ grains comes into play. Another check in the box.
If velocity (1050 fps) is the limiting factor, the only other variables we can increase is mass and diameter. I know that there are bunches that have arrived at this conclusion before me, I'm just expressing my thought process, which I greatly attribute to reading John Linebaugh's theories on his website. What I have yet to see however, is anyone that is machining sound suppressors that fit around the tube on lever action rifles. All I see is screw on cans...
My knowledge on the inner workings of suppressing sound is rudimentary, but I believe that they are deceivingly simple. Is there any reason why one couldn't machine around the tube on a lever gun, giving us the desired silence in a much more compact and aesthetically pleasing package?
