I recently began shooting long range, and I took my gun to a gunsmith to get a muzzle brake
on it. The guy immediately started bragging about his custom made long range rifles. I told him that i would be interested in one in the future.
He then started to say that his guns can reach 4000 fps in a 7mm STW with a 140 grain bullet. Is this possible or is he full of it? he says that his loads are "not in the books."
