Hey you all, here is my 2cents worth. I have had a m700ml SS, one since they came out originally a long time ago, and a second 26" barreled one I just bought from Bass Pro. I to had the misfire problem with #11's and musket caps. But I have long ago curred that problem. 2 ways this can be done - if you order the Cabela's 209 replacement kit you get a much better Canadian 209 kit, but you also get a stronger main firing pin spring, if I recall the spring is a 26# spring or two you can order a replacement spring from Brownells for a model 700 short action, but order the 27# spring. The original Remington spring is 22# - this is all from memory since I did this so long ago. If anyone is interested in the exact information and or part numbers I can dig that up for you just let me know.

Underclocked is exactly on point you do need to clean the bolt - but I do not think you to completely dissasemble the main spring and firing pin. Get a Remingtoin bolt tool and it just screws right out. clean it, dry it, lube it and put it back together....

Good luck all.....
