My step-son switched to the Variflame in his Encore and loves it. I tried it in my MK85 -which I converted over to a 209 - but it wouldn't fire at all - if I turned down the firing plug to a point it might. I'm not a believer in 209 ignition anyway (I know, it'sprobably just me) so I converted back over last fall to the #11percussion cap.Knight now makes an MK85 breech plug now that doesn't need to have the nipple removed first to get itout. Plus Ijust don't like the design of the 209 breech plugs compared toone that uses a percussion cap.
