RE: .44mag vs. .30-30
Danny, actually, we tested four rifles, two of my marlin 1894's (one a 1980's model and one a brand new 2003), 20" and 22" and two of his .30-30's, a 336 and a 30A, 24" and 26" respectively if I recall correctly....(BTW Is it the 30A or the 39A? One is a .30-30 and one is a .22lr, I just can't recall which is which at the moment).
We had two 4-16x glasses that swapped around and we each shot all four rifles (took two days!!). We did all shooting at 16x once things were sighted in (and other than muzzle velocities). All shooting was from a bench vise, calm "windless" day, sunny.
Mind you the following doesn't refer to all the ammo we tested, but what we get done with our pet handloads or best shooting factory ammo:
His 30A is quite good for accuracy, his 336 is a ways behind it, but still pretty good, if I recall he was getting 1.5" groups at 100yrds with his 30A, while his 336 was giving just a little over 2" at 100yrds.
My 1894's are a bit farther apart, the 1980's model has been ran ragged by my father and myself, I get 4" groups at 100yrds on a good day, 4.75" is more average for it....My new 1894 is superb on accuracy, 2" at 100yrds isn't asking much of it with good loads, it really likes Winchester super-x half jacketed soft points, and of course I've tinkered various handloads around to similar accuracy.
