I have been lucky and not had any mag problems with any of the “M” or “MIII” Professionals I have had. I love the bolt handle and prefer the double set trigger versions although the single set trigger is nice also. I have not had one yet that wouldn’t shoot under 1/2” with their preferred loads. I have had them in .25-06, .270, .30-06 and 9.3x62mm. I am only missing the 7x64mm and 8x57 I think.

Guns don't kill people, it's mostly the bullets
