i put 30 rounds of buck and about 20 #6 today. checked it after about 10 rounds to see if it was tightening up or loosening etc. with quarter. it was fine, kept shooting when i cleaned it no problems. that was breakfree clp souped up with some old brite-bore grease i had that was probably 30 years old.
dont thinks its going to be an issue, appreciated. but keep on goin cause i got a few older breakdown doubles too
