Jerry it just a simple matter of shortening the lug ramps. Really quit easy ;)

Why not just eliminate them completely? If your redesigning it I'm not seeing the need for the ramps in the first place if the bolt is all the way forward. I'm looking inside of a receiver right now and there are no wear marks on the ramps. You could get 95-100% lug engagement if they were eliminated.

When I get to that stage I will consider it. Right now I am still sculpting the outside of it. Its getting late though. I will try to do some more work tomorrow. This will probably take a month at the rate I am going cause I still have to do the bolt assembly.

Ben that's an awesome model. I look forward to seeing the bolt.

I'm thinking you might need some relief (or ramp), as the Mosin is a push feed design. You need the leverage of the bolt closing for the extractor to 'pop over' the rim. On all of my Mosins, the bolt body is bearing on the rear of the ejection port... pushing the bolt forward. Without ramps, you would have to pop the extractor over the rim before the receiver would let the bolt lock.

Tomas I understand what your saying about the extractor pawl jumping over the case rim. I've worked on this problem in my SV and in DW and have got the extractor to engage just sliding the bolt all the way in but not in battery. Do you think you could get away with a little bit of a ramp in the receiver and a little on the bolt lugs?

I'm pretty sure you could get away with ramps that were alot smaller... also thinking about this, the bolt body hits the 'ramp' at the forward part of the ejection port, the top, rear portion of the receiver ring. That part of the receiver might need to be altered/milled out too.

Surpluses secret project really has me thinking. What about 300wsm? it's about same case only fatter but no bigger then the base of the 54r. Would have to make it a switch barrel setup and that doesn't bother me.

I have thought about a 300 WSM Mosin a lot also. In fact a month ago I brought a spent case home from my buddies to try in the mag and such. I'm sure with very little modification it would work. The case fit in the mag but was snug enough that it wouldn't fall through. It took very light pressure to slide it. So I thing you could simply use a set of wedges to slightly expand the mag to allow the case to move freely. It would be such a slight expansion the eye probably wouldn't even notice.

Also only a very thin shim around the case head to fit the bolt

I say go for it!! A 300wsm is a little step up from the 54r case... external balistically speaking. You shouldn't have any problem finding a load that would be consistent out to 1500 yds.

I'm just throwing this out there... but you could make a dedicated 300wsm and use DBM's.

The savage magazines are double stack/single feed.

I'm sure it would be fairly easy (comparatively) to adapt some bottom metal for the Mosin that would accept the Savage magazine. The design of the magazine would limit the amount of receiver modification. The bottom lug would have to be squared though... like on Dmitry's 8mm.

Question for all of you. Do you know of any drag bags that will fit a longer gun. I estimate this things will be 55in long. And depending on the muzzle break/tuner this thing gets it will even be longer.

I would try Tactical Tailor. Call them and tell them what you want and they will tell you whether or not they can do it. Bet they can for that is how they started. The owner was in the Army and sniper also, but he didn't like some of the gear he was issued so he designed his own and modified his gear.
