Any advice for a pre-64 M70 rebuild

[LRPV]

I bought a "custom" pre-64 model 70 a couple years ago with all intents of never shooting it the way it was. Chambered in 22-250, the rifling was basically gone when I got it but it shot pretty good with a couple different loads. It is sporting a fairly heavy barrel, Canjar trigger, and a varmint style maple stock. The plan is to make this a hunting rifle for deer and coyotes. I originally was going to go with 6.5x284 just because I wanted one so bad I could taste it and I figured this action would be perfect for that round. I am past that now and looking to go with a 243 or one of the improved like the super lr or 6cm or possibly the Ackley. It has what I believe is the original bottom metal which is fine but have read that the one piece is better.?? If there was a detachable mag system out there that would work for it, I would go that way. As far as the stock goes, I want something different and as far as I tell Mcmillan is the only option there. The action is configured for the short rounds, a normal 243 will fit but I would like to have a little more room in there for some longer bullets. The plan is to use the 95vld Berger for everything and have a laser like trajectory. I used it in a 243 Savage and had promising results. I may end up using the 105-107, never know what it will like in the end. Do any of you guys have any ideas to help out here? Is there a smith out there that is considered to be the pre-64 guru? Thanks Jason

if you go with 243win get a 1 in8'' twist barrel, i shoot a 243improved ( specd the reamer to use 6 br dies ) get goo results with 105vld ,107 match king,

I was planning to go with the 8 twist but was going to try to throat it for the 95's. In my last 243 they shot extremely flat and they aren't that bad in the wind. I like the looks of the 243 br-k (is that what you have?) I just don't see much about it in recent posts. The 6cm looks promising with regards to barrel life with the 115's but not sure if it would be much different with the 95's or not. It won't be something that I will be banging alot of rounds through in a hurry so the Ackley may suit just fine. The main thing I can't find much of anything about are the magazine parts and bottom metal. I don't really want to spend 3-500 bucks on a one piece bottom that really isn't going to do anything more than I already have.

I have a 6mm BR barrel that is throated to keep jumped 107 SMKs out of the donut. The 95gr VLD jammed 0.010-0.015 inches seated out in the neck but is very accurate out to 1000 yards. This chamber/barrel shoots the 105VLD jammed, 115VLD jammed, and 108BT jumped very well with all of them seated outside of the donut. The barrel is a 1:8 Krieger 31 inches long.

Tony, I'm glad to know that you got that all to work. I wonder if the shorter neck on the 243 will allow it. I am thinking 8 twist canted lands barrel from Krieger or Bartlein. I have no idea what the wait time is but not in a hurry, yet. I have been following some of the .236 or .237 bore discussions in other parts of this site. I have a 6br with .237 bore that will not shoot the 105 Amax. Not sure if bore is the reason or not but the amax's that I have are skinnier than the others I have tried that do shoot well.

I have built several custom rifles on pre 64 Winchesters. I am now in the process of making two actions from scratch out of bar stock. I shoot a 243 for long range & have had very good luck with it. Use the standard case but throat it out long for the 115 gr. All Mod 70's have the same lenght reciever. If you want to use long bullets put a different Mag in it. Call me 715-372-8396.
