modern loads of old time straight walled cartridges interest me. I know they say the .38-55 Win is the parent for the .375 Win, but it's parent cartridge is the .30-30 Win.

I'd like to learn more about this kind thing with the old time .45-70 Govt and its big brothers, as posted earlier. :yingyang:

Round yourself up a copy of Cartridges of the World. Tons of information and hours of reading.
Excellent illustrations of pretty much everything ever made or dreamed up.
That and a couple of good reloading manuals that will give you case dimensions, velocities and range of bullet weights.
Great place to start.
 
The bullet weight and construction may be too much for the 375 wins velocities. Stabilization and bullet performance may suffer, If its in a lever gun it limits your choices even more.
 
Jacketed bullets are impossible to find. 375 H and H bullets aren't suitable. Hornady stopped manufacture of their 220 gr jacketed.

I load bullet Barn 265 gr gas check bullets but the accuracy is so-so. I just got some Jet Bullets that are a thou bigger (.376" vs .375" for the BB) so have high hopes for them when I get to the range. RL-7 is my go to powder for full velocity loads but Trail Boss gives a nice 38-55 level plinking load.
 
it wouldn't be in a lever, but a single shot...and reading on this cartridge, you can get bullets down in the 180g range. granted, those will probably be round or flat nose, being it was primarily a lever caliber.
 
IMO, The 375 Win is a great cartridge in it's own right, but be sure of the performance level you want. Don't try to turn a 375win into a 375H&H You can get some gains in a strong rifle, but there are limits. I've been down this road with a number of cartridges, some are worth it, some not, it's up to the shooter to decide on the level of performance he wants. There are usually issues, sometimes with brass life and sometimes accuracy. Safety should be your primary of course.
 
rimmed straight wall cartridges interest me...hence my query about the .375 Winchester. I likely will stick with my .45-70 and continue looking at the .358 Win (though not a straight wall cartridge). :)

375 Winchester a great pistol cartridge. I have a barrel for my Contender pistol. Very accorate. Full powered cast or jacketed are something that take some getting use to. I've shoot my cast loads out to 200 metres. Been using the Lyman 335 gr meant for 38-55 Winchester with a healthy load of IMR 4198. Reloading is the way to go with this cartridge. Last gunshow I found a box of factory loads and 26 cases so I should be good for while. Currently trying reformed 30-30 cases with starting loads with a 250 gr cast. Cases are on their eighth reload and no bad signs showing.

I've read that reforming .30-30 brass weakens it, making reuse questionable after a load or two.

Well eight reloads must say something about how good they are. I have also used them for the 38-55 when I couldn't get proper cases. Short but usable. Those had eleven reloads before I found 38-55 cases. Start with good cases and reform properly and you end up with good cases.
