Recently we put a Skinner peep on a 'no tang' Browning 1886 in .45-70. It has the dovetail cut into the octagon barrel. I have the Lee 340 and 400 grain molds. It is hitting about 16" high at 50 yards. I have been looking at front blades on the Skinner and Williams sites. Today I will measure the original and figure the height based on info from Skinner. Is there a better option? Thanks, Tom
