Hello to all.
Earlier I posted a piece on a 416/375UM and was very
pleased with the response.
After talking to all the reamer and die makers I could
find it appears the 300UM brass was used in two of the
wildcat 416,s with 40o sholders.
I use the 375 brass to minimize neck thinning.
The cape buffalo is a worthy adversary so the
416 Buff name is in honor of this beast.
After all testing is complete I will post the
I will be happy to share all information when finished.
