How does the gun shoot in someone elses hands?? As funny as it seems, a buddy of mine, very experienced gunner, was cussing a mauser he bought because he couldn' t get it to group even off a bench, he was almost to sell it, and I said I might be interested, let me see how it shoots, I put two snowman shaped holes in a piece of paper at 100yrds with 6 shots, told him I' d give him half what he gave for it, since it didn' t group for crap [&:][&:].

The question was how many LOADS and weights have you tried, in my favorite .30-06, federals of any weight and make don' t shoot worth much, premiums or otherwise, while with the same weights, Winchesters can snipe washington off a dollar bill out to 425yrds. You have to try different manufacturers, different makes (i.e. Win. Supreme vs. super-X, etc), and different weights, so you can find out if it' s only the ammo, or really the gun. If none of this helps, how' s the rifling integrity? that' s a no brainer, or how about what' s your actual bore diameter? It' s possible you' re shooting bullets too small for your gun (rare but happens), pretty much nothing you can do if it' s too big, without spending more cash than buying a new gun.

What stock do you have on it, what bedding set up (if any) do you have, what in.lbs. are your screws torqued to?? Try all this, then if nothing helps, take her to a smithy and have him look it over, see what he thinks he could do.
