Split Groups

[PLhunter]

Biggest change is a new stock. But the severity of the split changes with seating depth. All groups are worse since the swap but not all are split like this. It’s like when it tightens up it splits into two tight groups. Any ideas?

I had a similar issue after putting my rem 700 in a stockys. It drove me nuts for a year. I finally took it to a gunsmith and he found the pillars were loose in the stock. You couldn't tell by looking at it. Only once he drilled them out could you see how bad it was. He installed new pillars, rebedded, and it shoots great. He was convinced it was a bedding issue, I didn't think that was possible until he repaired the stock.

Okay, mine is a stocky’s Rokstok. It’s a tikka. I’ve been fighting it for a bit as well. It almost shoots okay but it’s shooting worse than with the factory and I’m more steady and comfortable behind the gun. So I think it’s a bedding issue but can’t figure it out.

That is a bedding issue without a doubt especially if your same loads shot better in the factory Tupperware.

How tightly is the lug captured in the stock? If it’s loose it would be worth bedding, and maybe also dab bedding the lug and tang areas.

Lug is in there so damn tight that when I tried to remove it with heat and vice grips all I did was chip it. That puppy isn’t going anywhere. It’s a touch proud at .094-.096. UM said it was normal. I can’t find anything that says above .093 is okay. I’m thinking of taping the top of the lug for separation and then bedding. Thoughts?

Try to measure with calipers the best you can and confirm if it's too proud, if so I probably wouldn't try the tape and bed idea. I've dealt with that before where the lug was a bit too big, and the action flexed with just enough torque on the screws to hold everything together for skim bedding. It audibly cracked when I loosened the screws after the bedding cured, and the only solution was to remove about .018" of material from the lug.

If the measurements don't appear to be obviously interfering, try reassembling by assuring the lug is in the action slot, tighten the action screws moderately snug, and drop it on the butt on the floor to seat it against the lug, then torque to 50+in/lb.

This values of .094-.096 are with calipers. Hard to ensure being perfectly level on such a small surface. Thus the range. The lug is 100% going in the action slot I have confirmed that with playdough . I’d remove material from the lug if I could get the damn thing out.

Also thanks for responding I was damn close to just taping and bedding.

What is the depth of the slot on your action? That one can be taken pretty accurately with calipers.

Make sure your bolt handle does not contact the stock at all. You can’t believe how many times bolt handle contact causes accuracy issues.
