Looking for some suggestions on a Model 70, fairly recent manufacture. Not the Black Shadow model, but the composite stocked, matt finish model W/ a 24 inch barrel chambered in 300 WM.
While I am certainly no master, I shoot allot and don't really have any problem shooting a gun with this type recoil and am very comfortable with it.
The gun looked to be old "new" stock and unfired. I cleaned the barrel well, mounted a Bushnell 6x24 scope on it with Talley one piece mounts and went to the range. At 100 yards, the first four shots were in about a 4 to 5 inch string, no groups, just a nearly verticle line angling to the right. After letting the barrel cool, The next one was exactly two inches high, what I was looking for, but the two following were two inches on either side. Fired several 3 shot groups allowing the barrel to cool between and could never get more than 3 to 4 inch groups.
Was using a good rest and the scope and mounts were very solid w/ blue loctight. I adjusted the trigger to about 3 lbs or so with very little, if any, creep. Trigger is very nice, crisp and consistant.
Ammo was Hornady custom 150 grain boat tail spire point bonded. I plan to try some other factory loads tomorrow and eventually get some dies to reload. I reload for several pistol and a few rile calibers already, just not the 300wm.
I am going to try to trim the stock under the barrel at it touches in a couple of places, but looking for other suggestions.
Thanks for any ideas

If you take care of the bedding that should cure your problem.The real problem is that when the barrel heats up and the metal slightly expands and the stock puts preasure on the barrel and causes a vertical string.

Agreed you have a bedding problem with the forearm of the stock or your bolt that tightens this is loose or changing?

Thanks,
But no, heat is not an issue.
I've given it time to cool and even if it was warm, this performance is not realistic.
The fore arm bedding is realistic and my next issue to address.
Thanks
