RECENTLY ACCUIRED A NEW NEF 243 SINGLE SHOT RIFLE, OUT OF THE BOX THE MOST INACCURATE RIFLE I HAVE EVER FIRED.I STARTED USING ACCURATE LOADS FROM MY YEARS OF LOADING. 85 GR SPITZER & 4350 WHICH DELIVERED 4" GROUPS AT 60 YARDS. I'AM GOING TO START EXPERIMENTING THE USUAL WAY WITH DIFFERENT POWDER & BULLETS BUT DON'T THINK THIS IS THE REAL PROBLEM . ANY IDEAS ?
with 4 inch groups at 60 yards Im not sure hoew much time I would spend with it before sending it back, but there are always a few quick checks like scope, scope mounts, action screw torques, barrell pressure points...
Handi barrels tend to be tight at the breech and loose at the muzzle!
Exactly opposite what you want. I suppose the a powder that burns completely in a couple of inches before the muzzle might be more accurate since less gas will escape past the bullet, but this is just a guess.
I had a 223 handi rifle and about the best I ever got was 6 or 8 inches a 100 yards. I swore that I would make that gun shoot somehow or shoot all the rifling out trying. Well there was a little rifling left when I got rid of it. I think part of the problem was it had a 1-12 or 1-14 twist and had enough free bore to shoot a 100 grain bullet.
