My brother had them re-barrel a Mauser 98 in 270 Win.. He gave it to me asked me to try and make it shoot. He was unable to get it to shoot well enough for his liking.
I got it to shoot 2-3" groups at 100 with hand-loads. I suppose many elk were killed with rifles that produce that level of accuracy. I expected better from a professional barrelmaker and gunsmith. Barrel was rough and copper fouled fast, took a lot to really clean it up.
Doesn't take long to put $100 worth of ammo not to mention time through a rifle. I spend my money on barrels with a better reputation now, and IMO much better gunsmiths.
Reminds me of an old saying, "something" like;
Produce a good product and a few will hear about it, produce a POS and hundreds will hear it.
In fairness, that was back in the 80's, and made me distrust them. I heard that they have re-tooled their shop and quality has gotten better.
