His theory, not mine, but i am happy to test it. I know the practice of floating has been common wisdom for many many years, i just think it's interesting that this particular custom gun maker thought that a proper stock made of well seasoned and sealed timber, fully bedded, would give better accuracy than floating. Depending on results, i can either leave it or refloat it. Bed barrel to end of barrel channel and do another round of load development to see if better accuracy is achieved. Run full load development to find best accuracy. Float barrel from 1 inch forward of action.
Rebarrel with light profile 1:14 twist 22cal barrel. I was thinking of going the other way around when i rebarrel the Zasty with my new wildcat (if and when funds ever allow!). Recrown? Failing all that, give up and do what you did to the Sportco. Study the shape of the group for vertical dispersion. In the case where floating does not work in a rimfire.
If you want to "effectively" shorten the barrel, how about the so-called "glue job"? A few inches of barrel are epoxied in to the barrel channel, while the rest floats. But is it more accurate? The only way to find out would be to fully bed first, try it out, then float it and observe the results. I do agree that barrel floating is cheap c.f. FWIW however, I come from a background where Every barrel floats and has done since the Omark was introduced. I might trial it on a rifle one day.ĭon't let me discourage you from your experiment. He had some nice rifles and solid comp results to back up his theory. He seemed to think that floating was the most common form of accurising because it was the cheapest, easiest thing to do on the production line. I was emailing a custom gun maker in the States a few years ago and his theory was that the best accuracy comes from a fully bedded action and barrel that is all along the barrel channel, effectively making the barrel shorter and stiffer and tightening the harmonics.
After experimenting with shims in the barrel channel, i found the right pressure point and epoxied some bracing in there. My Sportco 22lr didn't like a floating barrel one bit, even with the action bedded. So off to do some more reading.īedding action and floating the barrel doesn't always work. I dont really understand how you would find the pressure point IMO, forget it. and that a pressure point in some cases need to be added.
