My Rem700ML is still #11 percussion. But the nipple has at least 1000 rounds through it if it has one.

I have heard the Cabela's 209 conversion is very good.

I have also heard that Wolf springs are it for Rem700. I am on my second factory main spring that I changed about150 shots agowith one spare still in reserve.

De-priming tools (basically a fork to grab the lip of the 209 primer) are really handy to have. Sometimes the primer can "stick" in the carrier or breech plugand make it a pain to get them out unlesswith a de-priming tool/fork.
