If I did a conversion kit to 209 on My MK85

[T-Duster]

How many times can the red plastic 209 primer holder be used ? Before being no good.

I have reused primers discs, only one additional time per disc. I would use a new one for hunting.

I also would never use more than twice.

Well that is a trick question. You can reuse them until they no longer will hold the 209. I have used them as many as ten times without a problem with function. Now lets talk about the thing you give up by doing that. Number one thing I have seen accuracy change, next thing was delayed fire, because of less back pressure. The worst of things is the blow back and soot problems. For me I use a new one every time. Don't let 15 cents cost you the Buck of a life time because of a hang fire or a point of impact change. Good luck this year
