Re: .338 M.O.A.G. (mother of all guns) pics and story
Yes it has a Rem 700 Long action. For some reason the pics are a little grainy, don't know why, I may take some better ones and post them.
The 378 Wby and Lapua case size are max I will build on a Rem 700 receiver and then only using Chrome Moly receivers, no stainless one. The Chrome Moly is harder and will resist bolt lug set back much better then a stainless receiver will.
Also, I researched the Wby MkV to see how much baring and shear area there was on teh nine lugs on the bolt. In my experience, if there are 7 of the nine lugs in full contact you are doing very well with a Wby MkV receiver.
With a Rem 700 that has been properly set up and bolt lugs trued and lapped to 100% contact, the baring and shear area of these two receivers is very close to the same, in fact I have seen many Wby receivers with only 6 lugs solidly in contact to the receiver and in these cases, the Rem actually has more baring and shear area on the bolt lugs.
The V-Block is inlayed permanently into the stock and two or three mounting bolts pass through the block and are threaded into the barrel. Many will frown at this but to be honest, Hollnad has been using a somewhat similiar system for years and it works very well.
I have yet to see any disadvantage as far as accuracy goes using this system, in fact I personally feel the barrel is able to more consistanty expand and contract when it heats up compared to a clamp on block system.
This system also allow the scope to be mounted in a conventional height and is much more comfortable to shoot, again in my opinion.
It is also much less costly to build as machining time is much less.
As far as performance goes I have never pushed the Wby case until the primers let loose. I can get 3050 fps easily with a 300gr ULD bullet with very comfortable loads and 2800 with the 350 gr ULD bullets. Anything more then this and your pushing this case harder then it needs to be pushed, at least in a 34" barrel.
Another advantage to this system is that youonly need to remove the three 1/4-28 tpi bolts and the rifle can be taken down so it is very simply. IT is also extremely consistant when replacing the barreled action as point of impact rarely shifts from this. I still fully recommend check your zero when doing so though but seldom will it change.
I lengthened the bolt throw on the Rem 700 so that with the throat in my rifle, I can eject live rounds loaded with the 300 gr ULD and the 350 gr ULD Wildcat bullets.
This is a single shot rifle so there are no feeding issues at all to deal with.
