Howdy gents. I just bought an 1895 marlin [22 " bbl. made in 2006] at a pawn shop and I'm going to put the Williams WGRS 336 receiver sight on the receiver [I just ordered it from Midway, they're on sale] but I don't know what height front sight blade I need. Do any of you have experience with this? I'm shooting my handloads with 300 grain bullets at 2000 fps and 400 grain bullets at 1800 fps. I used this setup on a guide gun I had a few years ago with the Redfield Sourdough front sight but I want to use a .10" wide blade this time. I just put a Sims grind-to-fit 1" pad on it...much nicer! Thanks.
