Friend of mine is selling a Mauser rifle. It's had a muzzle brake and synthetic stock fitted, and rechambered for 338 Win. mag. Trigger is VERY light. Im not sure if it's been glass bedded. Mounted with a decent($200ish) Burris scope. He claims it shoots sub-moa with his handloads, which he is throwing in about 200 rounds of. What is the approx value of something like that?
