I have been looking at some of the smokeless powder High pressure inline muzzel loaders being built on remington 700 and other actions and then staring at a 458 win mag barrel i bought for a pistol build that never took off and the light bulb came on.
Im going to build a muzzel loader barrel for my switch barrel AK build. it should be really simple. add a threaded breach plug that will use small rifle primers in a cut down 223 case for priming andscrew that bad boy on.
the barrel an plug will handel at least 55,000 Psi and on top of that there will be a bolt with lugs to reinfoce it if the plug were to fail.
guys are getting serious perfomance by using normal smoke less rifle powder I was even considerin leaving most of the original 458 win mag chamber there and only seating the bullet to were the rifeling ends. I would expect near 458 win mag performace and certainaly beyond 45-70 levels. a 223 bolt would extract the made from 223 primer holders and I could likely use cut down x39 and even use a standard bolt. i was thinking of leaving the a mag there as a storage compartemnt for powder and bullets.
Oh boy wait untill the DNR sees me walking into the woods with a AK 47 with mag hanging out during the muzzel loading season not to mention in the restricted Zone.
there are guys shooting well under 1moa with the bolt action versions and doing it out to 500 yards. It will be the most powerfull ak that I can think of. At least for one shot at a time. it to funky cool to not build it. and it wont need a super long barrel like a black powder gun either likely a 18" will do.
A bigger calibur would be super easy as muzzel loaders are not restricted to .50 like center fire. I need one of those 30mm vulcan barrels hell a 50BMG barrel and a lot of powder could really be interesting.
I have no idea if a big chamber to hold powder that necks down to the bore is workable. seems all muzzel loaders are just a plug in the end of the baarrel and no chamber. I cant see why there would be any differance from a center fire if I used the existing chamber?????? I could actualy cut the neck of a brass round drill out the primer hole install it into a deeply cut chamber and then screw the breach plug in on top of it then use the case as a bullet stop and also it would eleminate erousion to the chamber as the powder would never hit the chamber.
im just thinking out loud here but a 500 grain bullet doing around 2100 FPS is going to leave one hell of a mark on what ever it hits. there will definatly need to be some sort of muzzel brake on this thing as well.
unfortunaly they dont allow optics with magnification. Hmm the rules dont say any thing about 10 power eye classes looking through a 1x scope however LOL
even a black powder barrel that is cheap and using pyrodex or something simular running normal black powder pressures would be interesting. can you imagine the looks on guys faces when you pull out a 54 cal black powder AK with a folder and a 30 round mag/ storage box hanging off the bottom ??????
