Howdy folks, I am in Missouri, near KC, and am new to this forum but have been a member of the traditional ML sister forum since 2008. I have an original, and as yet unmodified, Remington M700 ML in .50 cal. and a couple of stainless steel KP1's and a few ss barrels for them. I think these KP1's are terrific rifles! Just this week I got a gently used ss .50 cal. ML barrel and forearm for the KP1 that I have not shot yet. The breech plug it came with uses 209 shot shell primers. It arrived with the breech plug area being pretty dirty from blowback fowling and the seller made no effort to clean it up before shipping it. The KP1 barrels all have an extractor system under the breech end of the barrel, all the parts of which were pretty fowled and dirty too. I spent about 2 hrs getting it all disassembled and cleaned up. I have read here about a few of the aftermarket products that are available to help reduce/eliminate the blowback in-lines experience, some of which use a special breech plug or a modified plug in conjunction with primer adapters and a small o-ring seal. From what I gather, the KP1 breech plug evidently is not modifiable to use something like the Variflame primer adapter.
My question is, has anyone out there modified any breech plug using a 209 primer by drilling the primer seat just enough deeper to allow a small o-ring to fit under the primer to better seal the breech end against blowback fowling? I imagine drilling the primer seat only deep enough to allow the primer to slip in almost flush, just sticking up a little so that when the barrel is closed, the KP1 action's breech face gently pushes the front of the 209 against the compressed o-ring. Does this sound feasible, or am I barking up the wrong tree? Thanks for your comments in advance!
