I have a winchester model 94 bb in .375 winchester with 26 inch octagon barrel so I am waiting to see what you have found with your standard winchester bb. I also have RD's mould and sizer for the TLC379-235-RF which with my ww lead is closer to 238 grains and will be interested in what you found and I will use it with my bb and see what I get.
That'll be great. William Iorg will be doing the same. I'm waiting on a rear mount at the moment. This is an early one with radial holes on the reciever ring, The standard #95 mount is too high.
