Terrible groups with mcmillan stock?

[callen3615]

Hey guys, I have a bit of an issue. I have a 700 sps v in a mcmillan A4. I had it in an 700p hs stock and it shot fine (1/2 inch groups @ 100 on a good day). I got talked into a mcmillan stock by some people and I bet I havent seen a sum MOA group yet. I shot this weekend and a bit today and groups ranged from 1moa to 2.5 moa. All of the groups had alot more horizontal dispersion than vertical.

I havent had much time to shoot so I havent messed with it but this is really messing with my head now. I dont have a torque wrench, I just got it snug. This is the same thing I did with the HS stock and it shot great. I dont want to spend more money to get this stock bedded, if thats what it takes I probably will sell it and get another 700p take off stock. Mcmillans states that it doesnt need to be bedded, and I have heard of people getting great groups without bedding.

Any ideas?

That would be the first thing to check.

I know this isn't what you want to hear but...YES, you need a proper torque wrench if you want any degree of consistency (its a cheap insurance policy) and YES, you probably need to bed it!

Well I bought an A4 and removed my 700p stock off of it and it shot better. Granted the A4 was bedded and pillared properly. Never again would I go back to that HS stock. Just my experiences.

Pillar bed and skim coat it!

The HS you sold had an aluminum bedding block, the McM has no such thing, you need to bed it to get the most out of it....

The last thing on a rifle,that I want only "snug",is it's handle.

Wouldn't be surprised that it's assembled incorrectly too,with the magbox bound and shy of being seated fully into the receiver as well.
