Thanks...I have many of Mic's artricles but couldn't find the specific information. Been surfing the net for the past two days looking for it.
Can't believe that information isn't scattered all over the web or here...can't even find information on the "V" threads on the newer rifles.
I want to do a wildcat 416 cal on the 284 case or a belted magnum with the belt turned off. Boring the threads on the receiver by about 0.035"-0.045" and decreasing the minor depth on the barrel threads should equalize the difference in case OD between my 356 Win .473" base, the 284 .500" base, or the .513" nobelt, belted mag case and keep the pressure ratios the same.
I know there are a few 416 wildcats out there on the different 444 and 45 cases, but I always seem to go for the "totally oddball, whowouldhaveguessed" stuff and way too much trouble for most, but I've been a wildcatter for 50 years and can't stop now.
Guess I will have to pull the barrel and measure...just trying to get the calculations done BEFORE tearing things apart. I want to have the new barrel/ammo ready so it's just a quick swap...maybe.
Thanks again.
