I have the 4-16x50IGR Sport Dot mounted on my .243 Ultra Varmint and the 8.5-25x50IGR Eraticator mounted on my .204 Ruger Handi, both in
medium Burris Signature Zee rings.....Hammer clearance depends on how the scope needs to be positioned for your anatomy, for me, it works great with the power ring just ahead of the hammer.
rbjaw, you might think so, but that's not always true, due to the high mount position of the scope rail, there's plenty of room for clearance of the objective bell, but not at the hammer, power ring/ocular bell, it just depends on the positioning and size of the ocular bell/power ring. Most Handi/Ultra owners have to use high rings.
