I've yearned for a 38-55, or even a 375W, loaded to 38-55 pressures. The allure is powerful. Nostalgia, I suppose being a part of it. I could see me using the 38-55 exclusively, say as a "one rifle," but in my digs, it would be off-optimum to a significant degree. Nice to have - the cool-factor being what it is. I believe a very effective deer round for the type of hunting I'd do around here as well, and fits within the "straight-wall" boundaries to boot.
Alas,...
Not wanting to keep track of and keep up with thirty long-arms, I did a lot of very careful... BRUTAL analases of pros/cons, wants/needs, etc. and decided that lobbing less lead each shot would be easier on the "lead" stash and easier on sorely abused joints and bones. Oh, how I'd LOVE to have a 38-55, but then I'd still need a smaller-bore gun for flatter shooting at smaller varmints at longer ranges also.
The 30/30 might not be as cool as the 38-55, but the 30/30 is still one amazingly versatile old gal. I have a dandy 118 grain "squirrel load," which will do head-shots at least to fifty yards on the little buggers. But then I also have the capacity to load any of a number of 165 grain (and up) bullets, ahead of a full, factory-load charge-levels of powder and it STILL won't abuse me.
Sooo, the 30/30 IS a "small" bore version of the 38-55, yet still capable of hunting medium game and plinking at 200, etc. Practical, economical, easy on the powder and "lead" stashes, easy on the nut behind the trigger, not lacking in nostalgia...
It is another "perfect combination of compromises" in this case. Not the best at anything except being the best at covering a LOT of bases, checking a LOT of boxes, even if it's not a big-bore thumper, not a "stretched-string" small bore, but has at least one foot in each of the two realms enough to add some challenge to implementing it in either extreme, yet comfortable, competent and confident in the middle.
And if you CAST, well...
Yeah, I'd LOVE to have a 38-55. Am I depriving myself? No. I'm having the same kind of fun, don't feel like I'm missing that much really. Just all part of finding just how much fun not having exactly everythingh I think I want can be. If you already HAVE a 38-55, probably a different story. If the 38-55 beats you up (abused old bones and such), load down or add another gun to the safe. If you have 12, 20, 30, what's one more?
