There were a few questions concerning the 44 BGM on Molemans 357 AR thread .
Moleman an I spoke via PM an decided to give out more details .
Im sure he will be along to give more details as well.
this is up an running round on his Mauser .
I originally envisioned the round in a AK 47 . I also had a longer version that ill call the 444 BG . The same reamer will cut both chambers .
A rimless 444 marin has been done before . this is a little different .
As far as comparing it to a 44 auto mag its a lot more. the closest comparison is a 444 Marlin that this round can duplicate or exceed depending on action strength or be down loaded for AR 15 use .
I and another member here ( Moleman ) have been working on a 44 cal wildcat based on
cut 30-06 brass ( or similar ) for a few years .
Its case is 1.799" long making it legal for MI an other states that have the 1.800" long straight case rule . Loaded to 60,000= PSI it will exceed 444 marlin velocity's .
it will fit in a AK or AR length mag as well as any bolt action running a .470" bolt face.
Loaded to lower AR 15 power levels it will out run a 44 mag by several hundred FPS an be on par with a 458 Socom or 450 Bushmaster for a fraction of the cost if you hand load .
Bullets from under 200 grain to over 400 grain can be used . the round has subsonic potential.
It can be loaded with 444 marlin dies an a few other off the shelf things .
Moleman has beautiful working Mauser chambered in it .
I an others ( Gunter an Moleman ) on Gunco originally designed it for use in a AK 47 that is a bit stronger than a AR . Since the MI an IN laws have came about the round has become more interesting to many as a deer hunting round . IMO its a great 200 yard an under deer round that delivers a lot of energy an pretty good trajectory.
We are looking for a good pointed cast bullet for this round in the 250 grain range or any range for that matter . Something for tipped for a auto loader .
