light bullets
Re the carbine, I have the .357 version, pre-safety, and it has been a dandy GP/woods rifle for a long time, till I started having trouble with the sights and slipping vision. On my early .357 rifle, the quality is quite high and I have always been plenty satisfied.
Re light bullets in .44 Mag. I started down that path quite a few years ago when an early Ruger .44 carbine (twisted 1-38) would not group 240 gr bullets to my satisfaction. In fact, two such carbines display such a tendency. Basically minute of "pie plate" at 100 yds. Some Rugers / Marlins do better, but mine will not.
With such a slow twist, I figured a lighter, shorter bullet would do better, accuracy wise, and the carbines responded well, yielding 3" groups or so and giving enough accuracy, (for me) for a woods carbine. I've shot both 180's and 200 Hornady XTP's, and taken deer with both weights. I've not had any of those slugs exit a deer. By comparison, I've not ever seen a 240, mine or my Dad's, NOT exit. I've picked the 200's over the 180's for deer and here's why.
I found that the 180's were a "soft" bullet, and per Hornady literature, intended for .44 Special velocities. Driving them a good bit faster down carbine tubes yielded a very explosive bullet, especially up close. I fired a second shot at a buck that got up as I approached, under 10 yds, broadside on the ribs, and the bullet exploded internally, did not exit. The jacket/lead shredded, and the found fragments resembled chewed gum. The damage was major, and a dead deer, but I did not like the frag nature of the results. I'd think on something like a big hog, or B.bear, the bullet would be a problem.
The 200 gr Hornadys are intended for rifle velocities, (again per Hornady) and hold together much better. REcovered bullets have not fragged or separated and display extreme mushrooming. Difference in accuracy between 180-200, in my carbines, is not discernable. I've not had any exit a deer, but that is not a problem for me. On a pure broadside shot, I think they would, but every buck that has presented a shot when carrying the .44/200 combination has been quartering, and the off shoulder has caught the bullet.
I really wish my .44's would shoot the heavy bullets. The new (discontinued) Rugers are twisted 1-20, and should, as are most .44 revolvers, (+/-) and I think there is merit for a heavy .44 slug. Back in the day, I could out group my carbines with 240's, using a 6" M29! (alas). But my old carbines will not shoot them to suit me.
