That is interesting as it would make finding cheap brass possable for a rebated 444 marlin build.although it would have to be straightend out.The .444 marlin was originally made from untrimmed 30.06 brass in development by Remington.The rim was left untrimmed for .444 & trimmed for 30.06. The first .444 cases were headstamped 30.06 Remington. Hope this may help.
tromix has already built a 444 marlin on a 410 sagia all ready. the chamber pressures between the 45-70 and 444Marlin are very simular when loaded with smokeless powderThe 444 is loaded to around44.000 CUP. I under stand that he actually is taking orders for them. Even though the 410 does not make that kind of pressure dosent mean the gun (IE BOLT AND TRUNION) wont handel it. the trunion is pretty much the same. I dont think a 45-70 will fit in a sagia Mag as it is the round is aproximently .100 larger in diamiter.(I could be wrong).
What is the current cost of a psl kit?? trying to figure what the total build cost would be.
A 45-70 would certanly be impressive aswell as severl others that are simular .458x2, 450 Marlin(basicaly a 45-70 but designed to handel hotter loads and not chamber in the weaker 45-70,s),450 Alaskan there is also a 45-60 that is starting to make a come back. that may be even better on a AK platform case is 1.89 long
