I'm looking for advice on an attempted fix for my (formerly) most accurate CF rifle (well under MOA). Thanks in advance for any shared experiences or advice. Here's the story:
I got a great deal on a Winchester M70 243 WSSM with a flexi-flyer cheap plastic OEM stock and blind magazine. I immediately installed and bedded a Hogue aluminum stock to it but no single piece floor plates were available for it so I designed and 3D printed a cover for under the mag well and retained the blind magazine, original trigger guard, and 3 screws. It was super accurate (dispelling the rumor that chrome lined barrels are inherently inaccurate, BTW).
PTG finally did a manufacturing run of single piece bottom metal so I bought one for the door feature and aesthetics. The one-piece bottom metal does not use the often hated middle trigger guard screw, of course. Now the rifle can't shoot under 2 MOA! I've tried all kind of screw torque sequences anywhere from 25 to 60 in-lbs to no avail.
The two potential corrective actions that come to mind are:
1. Dremel out some of the bedding epoxy and re-bed.
2. Cut a third machine countersunk hole in the PTG bottom metal and install a third screw in it.
or I could regress
3. Go back to my 3D printed cover.
What do you think?
Thanks,
Cal
