Also own a 444S, 1977 model, bought it new in 1978. The only reason I buy the Rem 240's is to plink and keep the brass (and now, at $50/box, I don't even do that much anymore). I reload and have developed a super-accurate load of 42.9 Grains IMR4198 over CCI primers topped with a Hornady 265 Grain FP. It's not a "Hot" load by any means, but I can reliably achieve less-than-MOA @ 100 yards with it, and none of the deer (and the one bear) I've ever harvested has complained very much. And the load is a whole bunch less than the max specified.
With the 444, you don't need high velocity, just pretty much accuracy. While some will claim effectiveness out to 175 - 200 yards (and I have no reason to doubt them), here in Ontario with the bush I never see shots more than 75 yds or so max in the field.
Also, I tend to baby my almost-40-year-old "JM" 444 quite a bit, it still looks pretty much like the day I unboxed it, and the moderate loads aren't as tough on the barrel as the high powder charge shots.
