I've had awful accuracy problems with my Nitro Venom and I thought I'd checked everything.

Today with the .177 barrel I was all over the place, so I switched barrels but the .22 wasn't much better.

Then I re-thought something that had occurred to me before, but I hadn't taken any action on.

The front bolts want to pull through the wooden stock, and I've repaired the holes, but if someone had said to me "The front bolts shouldn't want to pull through but just compress the wood when they're tightened." I'd have thought, "Well, duh!! of course."

Since the stocks are made by computer guided machines I thought they should be "perfect", but I finally reasoned that there must be a high spot in the stock preventing the action from seating nice and flat on it.

I always align and start the front bolts first, then start the rear bolt, and I had noticed once or twice when I tightened the rear bolt before the front two, I could feel the action move in the stock. That was my warning that I ignored.

I don't have a way of checking for a high spot except rocking the action, so I just took my Dremel and routed out inside the entire stock except where the front bolts fit. The rear bolt attaches the action through a metal spacer, so it's fixed in that spot.

Took the gun out, bolts stayed tight, accuracy problem "fixed" (I think/hope). Anyway, the bolts won't want to pull through any more.

I feel a bit dim for not having figured this out a long time ago, but thought I'd post for the benefit of others who might have the same problem with the front bolts pulling through. That's just a symptom, the problem is inside the stock.

Peter :D

My Nitro Venom stock would always loosen after about 50 shots or so no matter how tight I cranked them down.So I switched out the wimpy Phillips screws for two hex heads and blue loctite and cranked them down with a socket wrench.You can really get a lot more torque than you'd ever get with a Phillips.Its been two months now and thousands of shots and its frozen solid....hasn't moved a micron.

I remove, then locktite all screws on my springers. The worse was a BAM29C- 3 to 5 shots and they'd be loose again. Lock-tightening the screws resulted in them staying tight - but didn't do anything for it's lousy ACCURACY! :lol:

Best Wishes
