The way the VersaMax self regulates, the gas pressure is accumulated by an array of vent openings in the forcing cone area. The shorter the hull, the more openings are exposed. Theoretically, this is an interesting concept; however, with gas guns, the farther back the gas vent is located, the more fouling they accumulate -- the forcing cone is probably the worst location for vents. Typically, gas operated rifles have a tube to collect the gas from further up the barrel (one gives the Kalashnikov its distinctive profile), this is to minimize vent fouling. Since vent fouling is a problematic in the large, mid-barrel, vent hole/s of the R-1100 and R-11.87, what happens with an array of smaller holes at the back if the barrel?
Another question, with the vents in the forcing cone area, what happens to the hulls if you're a reloader? Will the 3 and 3-1/2-inch hulls tend to self destruct where they cover vent holes? Unfortunately, the Remington site doesn't have the VersaMax owners manual available, so we can't peruse the specific ammo recommendations and cleaning procedures.
I'm a Remington owner; but, I don't think I want to be the first one on my block to have one of these new Remingtons, do you?
