A little off-topic but I'm experimenting with 209 in my Rem 700 ML. Ignition is iffy with the factory vented nipple ,as was predicted by the manu. My question is: Does the nipple screw out of the breech plug on the Rem or is it made in one piece ? A couple of places offer replacement nipples to work with the BH 209 but damned if I can get the nipple removed from the breech plug without fear of Bubbaing it up. Help or info would be deeply appreciated.
