Well DH. The 742 is after all a hunting rifle and tolerances on it are SUPPOSED to be a bit tighter than military stuff. Suopposed is also a key word here. I use the small base for it out of hand..it WILL work that way. As far as ARs. I have found that now days they are being made somewhat tighter especially in the case of varminters etc..and since most of what we see are civilian models they seem to be somewhat tighter. On checking an old Mil Spec 16..tolerances are quite a bit looser than my Bushy Varminter....but they really have to be. They get very hot very fast. One of the reasons for the VN era problems along with cleaning. Newer cleaner powders now too. Try the regular dies. They well probably work..also keep the case length right and the overall length in the middle too. New heavier bullets really use powder space and many want to seat 'em farther out. Max length can cause feeding difficulties. My Bushy has that problem with 69 gr Noslers at max length. but they do shoot..really well. I got 1500 of them a couple years ago at a very good price(6 bucks a hundred) Yeah..I'm cheap
