Have an SWFA 1-6 on a 375 H&H. Been great. Really like the reticle; on low X it's like a large aperture peep, crank it up to 6 and you get the bare MQ. Had a Leupold 1.5-5 on it before without any trouble.
Had a number of 1.5-5's through the years, most on relatively heavy kickers such as 45-70 levers, 450 Marlin, 378 W. While I have had troubles with some larger gold rings that were dialed on, I haven't had trouble with the 1.5-5's.
