RE: remington 700 ml
Skeeter,
With the Canadian Cabels 209 system I really don't get that much blow back, more soot and material from the primer than anything. I have made three or four of these shot gun shell primers - still have the original on the gun - haven't blown one yet on a Remington... the A&H on the other hand blows them right away. The trick is with the Winchester 20 guage is to cut the plastic off just slightly above the brass - the plastic is the thickest there and will slide on the bolt snugly.
With a Remington you already no that cleaning the bolt is part of the religion of shooting a Remington. When I am able to go to the range I shoot 20-30 shots without any problems. I am shooting 100/110 grains of t7-2f - I really like my Remingtons. In fact somebody once asked -"if money were know object" ya know for a hunter like me I would still pick the Remington SS
