Nomercy448 that looks like a very nice custom rifle, most of the sites members would love to own something similar.

one of my long term hunt clubs most dedicated members has a browning BLR in caliber 308, he's used for 3 decades to kill elk consistently with,
the load he has used for decades is simply 47 grains of WW760 over a fed 215 primer and a speer 200 grain bullet seated to max length the magazine allows
hes killed enough mule deer and elk to be very confident in his ability with that carbine.
and in 30 plus years Ive never known him to need to shoot, exceeding about 250 yards to fill a tag,
the expansion characteristics of the 200 grain speer, at the 308 velocity seems well matched

his BLR could be a clone of this picture I found posted else ware.
