I have several rifles that must be cleaned from the muzzle. I cut the base off of a .243 case to use as a muzzle guide for the rod. Also makes a funnel for adding more solvent in the case of heavy copper fouling.
The 742 is a bit of a pain to clean. I've gone through a few owned by friends when they got so gummed up so as not to cycle anymore. Rule of thumb with these, keep the bore cleaned and lightly lubed with a penetrating oil such as JB 80 or Liquid wrench. Same for the action. Do not perform a full strip and clean unless it is starting to miss cycles. If it slides grease it, if it moves oil it. I use a Moly based lube sparingly on sliding parts on my semi-autos, it's a Zep product I get from work.
2" would probably be par for these rifles, but some will do better. They prefer 150-165 bullets with powder in the 4895-4064 burn range near max. You'll run into cycling issues with slower or faster powders. You could certainly try M1 Garand loads. If they cycle and shoot well, go with them, you're basically turning it into a .300 Savage and that round has killed a lot of deer. That's what I shoot in my 30-06 rifles, including the M1 and an M17 sporter. 47 gr IMR 4064 in HXP military brass and various 150 grain bullets. Mild shooting and accurate, even to 600 yards with the 155CC. I'm away from my Hornady book right now, but I believe H4895 is in that same weight range. The 150 Sierra PH is a deer hammer at these speeds. These rifles tend to be hard on brass, I would source some LC or HXP military brass. It is a little stouter than most commercial brass out there. I've never felt the need for small base dies, just a good full leverage crush on the FL die with a couple of seconds to set the resize, and I shoot several semi-autos with tight match chambers.
