Yeah, Bigcountry, I have not been stymied by new calibers in the past, but that 300RUM was too much of a puzzle. After four different propellents, five different bullets and countless load data, I figured that I had been whipped and sent that Browning/300RUM rig down the road.
The Winchester Ultimate Shadow in 7mmWSM is working out really well and if what I hear on this list is true, I should not need more then a 140gr premium bullet in 7mm anyway. The Winchester was shooting well, but I had a trigger job done anyway, as the trigger was a tad stiff and did creep a bit. Will report after again range testing.
Thanks for the help that you did render. Steven
