RE: BH209 With Rem 700ML ???

I have two of the Remington 700'swith the "Cabelas" 209 conversion and I am certain they will work - I did shoot some BH-209 in a White and the Remington is essentially the same.
If you a havea Remington conversion - you might get quite a bit of blow back, but with the Cabelas conversion - that should be limited - but I would bet it will spit your primer out of the nipple and possibly re-cocked the bolt. If you are using a weather shield this will all be held to a minimum.
