HC I was referriorng to the 10 round sagia mags not working correctly with a STANDARD444 marlin in the Tromix conversion. It is obvious there is a issue with it using some factory loads or Tromic would not have shelved it.(I should and will keep my rimless project on a seperate thread )
I have no doubt that IF TROMIX wanted to modify a mag and or reciver it would be doable. I was looking at a used sagia 410 to modify thus weekend but passed. I have one 410 now but dont plan to modify it.
The 44super long would be a great round I dont know if it would be any better than the 450 bushmaster but it is possable that the 450 AR mag could be modifed to fit a AK. the firts step in my mind to building a 44 superlong would be to come up with a standard dies that will size the brass and a way to seat and crimp the bullets. the next would be a way to ream a chamber Of course a custom one could be cut for about $150. I personaly make the round longer to take the full length of a AK mag with the heavyiest bullet avaliable or usable.the beauty of this round would be the use of 30-06 brass and the avalibilty of it.
