I'm modifying my first Mauser - VZ24. I've re-barreled the action, chambered for 338-06 AI. I'm up to inletting a very pretty and pricy walnut stock, but I need to solve my bottom metal problem first - a new one from Sunny Hill or similar is in the $450 range, so that's not ideal. I found a steel one on Numerich for not too much money - internal dimensions are 3.38". I'm wondering if that will give enough clearance for this round with 250g bullets? I've found only a couple of references to 338-06 OAL online, but nothing definitive. Regardless, I thought I might try to lengthen my existing magazine box, but can't find any references for this job. Anyone know of any? I sure wish some lazy gunsmith with too much time on his hands would get off his keister and make some Youtube videos of this stuff for me! If all else fails, I'm going to just buy the brass and a chamber plug to measure my lands - then I can load a dummy and see what my no kidding OAL is. I may have just answered my own question, but will still post to see what others have done...thanks in advance.
