wow I didnt relize that the 300 savage had been used in so many differant civilian versions.
Using a stamped receiver with a front trunnion the G3 magazine is too wide and wouldn't leave any material in the trunnion, or not enough even thinning the magazine. The FAL magazine also seems wide and it doesn't seem a good choice for a rotating bolt. The M-14 magazine seems the best fit so far.
HMMM. there have been guys who have used g2 mags in a 308 ak conversions it requres a thining of the trunion and the mag also but they will fit and there is some pretty thin metal. the one I know of is a screw build as there is no room for a rivet, things were very thin but a $2 each I may give it a try even if I have to really mod the mag. the mag does not suport the round at all in that area and you could likley remove the enitre top front area back to the center of the follower stop with a grinder in about 3 minutes.
I have also seen fn/fal mags used. what is the reasoning for the fn/fal mag not working ? you mentioned rotating bolt being a factor. I see that the mag it not cut away/ droped down in the front. so getting it high enough in the trunion would be difficult.
I havent got a m 14 mag to play with. my 308 conversion used a rare m77or 76 mag (cant rember it was a 308 mag however cost me like $40) but there way to pricy and hard to find to recomend.
What I really like about the 300 savage again is the lowere SAMMI pressures. other wise a hand loaded reduced pressure 308 would be likely better/safer (and not saying it is unsafe to begin with) as the brass is way cheaper. my grandfather killed a lot of deer with a savage lever action in 300 savage. it seems to me that the new 6.5 Creedmore IMOA is very simular to a 6.5-300savage wild cat. the Creedmore is another round I am giving consideration to for a long range varmit build. they run at lower pressures as well.
I have three spare yugo trunions (and looking for a few more) that are going to have differant barrel asemblies built up and then be swapped out on the same reciver. there is going to be a 243win light barrel coyote barrel. a 6.5mm either a 260 or a creedmore or some wild cat heavy barrel long range varmit build and another .308 dia round possably a 300 savage or more likley a 308 win on a lighter hunting weight barrel.
the 444 may also get done initaly on this reciver although it is destine to be a hunting pistol round for my use. I have not rulled out a 22-250 or some other 22 calibure round like the 22 bench rest but the pressures will have to be kept down.
the yugo trunions have extra meat making a screw build even more attractive not to mention one of the forward holes runs completly through the trunion so it wont even need to be threaded just cross bolted. im invisiong one big gun case holding a reciver and three or four barrel assemblies plus a pistol trunion and short barrel set as well. the reciver will be registerd and built as a pistol first.
My ffl recived my recivers today. I am going to use a NDS-5 for this, my first 100% reciver. it will have to have the LH ejector rail removed as well as the cross member and mag well opend up but for $83 it will transferable and regiserd as a pistol plus no one has the bent blanks right now. I hate to cut up a perfetly good recive but I figure I am only loosing about $50 over if I made my own factring in the cost of the blank and the FFL fees ect. I am going to do a custom trigger guard and a have been looking at ways to save finger clearance. posably going to a AR stle mag release or some thing simular
has any one ever seen the french MAS mags were the mag release is on the mag and locks into the hole on the side of the reciver? I was thinking that would save over a 1/4 inch by removing the mag latch from the trigger guard. I need to be able to wear gloves HMMM
interesting I defenatly want all my differant rounds to work with one bolt and extactor assembly. I will have to be sure to get my hands on some IMI brass before modifing the bolt and extractor to ensure that it will run on any case I choose to use in the .473 rim diaThe 308 rim is slightly thicker than the 30-06 rim but not by much. The military wanted to strengthen it for auto weapons. IMI 308 cases have rims thicker than military specs for 7.62x51 and can cause problems with tight extractors but not often.
