I have used 271 grain Hard Cast gas checked bullets in my 375. They shoot very accurately from 1500-1800fps. Haven't shot anything with them as Like Mainer I like some expansion. I have a 290 grain mold that will likely cast a 300 grain bullet and it is supposed to do very well in the 375 but I haven't got into it yet.

However tested on ballistic media what you get with an expanding bullet is a wound channel that looks like a turnip with a tapered tail at the end. Basically you get a rapidly growing wound channel that creates massive destruction for a bit and then closes up creating a very narrow channel at the end. With 255 grain bullets the channel will be about 12-20" long depending on media density. This large diameter channel creates a lot of shock and fast kills especially on smaller big game animals.

The Hard cast creates a carrot shaped wound channel. The wide flat point does create a bigger than caliber channel but one that is much less wide and much deeper than that of an expanding bullet. It penetrates 50-80% further but will not create the sudden immense shock, it will however be similar in width throughout it's depth. I would expect slower kills, and unless the animals are huge..over penetration. If the cast is the right mix of hardness without being brittle they should do really well on bone. For really big animals the penetration might be helpful but the 375 Win is not a giant killer. It will take moose but I wouldn't use one on Bison.

For game in its class the soft points are the way to go. An argument could be made for hard casts for Grizzly protection to allow penetration into the CNS. It's arguable at least. Not sure about that yet myself though.

IF one of you guys could post a load for the heavier cast bullets, it would be most appreciated. The load I tried was primarily a 38/55 load using 23gr of 5744 and it sucked.

I have been using 28.5 RL 7 with 271grain gas checked hard cast and Starline brass. Gets good groups and prints close to 255 Barnes in Win Brass with 32.5 RL7. Wasn't going for max just a good shooting load. Have not chronographed it.... probably 1650 or so?

Fellas I have two 38-55's a '94 Win and a Uberti Hi wall with different twists.. 94 Win = 1:20 Uberti =1:18 ... Not a lot of difference but seemingly enough to keyhole my 325 gr lead gas checks shot from the Hi wall however they stabilize and group 2" at 100yds via the Winchester 94.. Having played with several sizing diameters both shoot best when pills are sized .380. The 23 gr 5744 load I gave Jorge so far gives me excellent accuracy/vel and burns very clean with magnum primers.

I've also compared loads with the short 94 case vs the longer case for the Hi wall without any significant difference using the same bullet and diameter..just wish the Hi wall would throw the heavy like the Winchester.

Having checked further the Pedersoli 38-55 Hi wall has a 1:12 like the Winchester 375's. .

I load 28gr of Reloader 7 behind a 300FNGC for around 1850 FPS. That’s in reformed 30/30 cases. 375Win brass is a little thicker so you might drop it back to 25gr and work up. It’s a punchy load in a light carbine. Accuracy is brilliant.

The 375Win has a long throat, presumably designed to blow off pressure quickly, much like the 458 Win Mag. It’s Winchester’s answer of making a short case perform like a longer one. The throat is so long that you can’t load a bullet out and have it touch the lands and still cycle in a levergun. This problem is exacerbated in straight wall designs. The best way to get accuracy in these situations I find is to load as large a diameter pill that will still chamber freely and cycle. This helps centre the bullet in the chamber and align it with the bore rather than having it slump to the bottom of the chamber. A longer cast pill with a bore riding nose is better for accuracy as the front engages the rifling while the base is still supported in the case.

FYI the throating in the 38/55 is totally different to that of the 375Win and the standard twist rate in a 38/55 is 1 in 18”.

Most mould designs in this caliber are designed for the 38/55 and have a relatively short nose. You really need a Lee FCD so you can crimp in place to load to 2.55”.

I’ve shot fallow deer with mine and there was no sign of the bullet pulling up in game of that size. Penetration was complete, even on quartering shots. I need to take it out more but with ageing eyesight I tend to hunt mostly with scoped rifles.

I purchased a good mould for this caliber but have yet to try it on game. It’s a 250gr HP mould. With a suitable alloy it should provide rapid expansion and good penetration over a wide range.

Thank you guys for all the data. Woody that load from North for your 275 hard cast should work ok. Going to give it a try this weekend.

Thanks for all that North, I wish Woodleigh would make a 270gr flat nosed Weldcore for the lever guns.

Dang Jorge, just came in from the load shop, i'll grab my load book in the morning, it's a modern 24 inch barreled 38-55, but, bet I'm loading it close to you men's 375 Winchesters.

Good lord what a crazy wet muddy day on the farm, after two dry shirts, another pair of jeans and a dry pair of boots and socks I finally made it out to the load shop.

my 38-55 WCF load:

WW brass
260 or 265gr Cast Performance or Beartooth hard cast gas check bullets
32 grs RL-7
FED-210 or WLR primers
COL 2.490 inch, good roll crimp in groove
Vel. 1855 fps

It's a hell of a load in a modern 24 inch barreled 38-55 WCF, and would be a good spot to compare loading for a 375 Winchester.

If you don't mind: What are you shooting this out of?

IIRC the Winchester Legendary Frontiersman was made in 1979, a completely safe load in my rifle, accurate, more than easy case extraction, and have never came close to loosening primer pockets, I bought 250 sticks of Winchester brass in a white box years ago, am still on the first 100 cases and believe they're on their third loading.

Something about sitting in a chair out in your pasture and ringing 1 and 200 yard steel shooting off a crossed leg with a lever action rifle and Lyman receiver peep. smile

Edit to say, my bullets are sized at 380 inch, also, with the 38-55 having thinner brass [more case capacity], pressures will be lower across the board when loading high performance ammo, and lastly, with my rifle having a 15 twist, shooting the heavies is a piece of cake.

I really need to check the bore size in mine. I have a beautiful recent production '94 Deluxe Carbine. Info from Winchester is bore = .368" and grooves = .376", +/-.02". Thank you for the details.

You're quiet welcome Sevastopol, .379 and .380 inch shoot great in my rifle with no hint of leading, good luck and happy shooting.

I use Williamiorg pressure measurement on my 30/30 and 38/55. If the fired case measures .420 ahead of the rim it’s good.
Winchester brass, Winchester LR primer.
NOE 265 grain hollow point sized to .378
Re7 at 33 grains
1972 high 1955 low 1961 ave 17es 9 as
Very accurate. The hollow point is .115 in diameter and .275 deep. Difficult to measure. Bullet length is 1.025.
Damn good load and bullet for thumping stuff. Maybe I can find a Bear this spring.

Picked up a Winchester 94 legendary frontiersman in 38-55 in like New condition. Im going to have to put some ammo together as I want to make this 38-55 my goto rifle. I've already got a 348 winchester, 348 Ackley, and my 338 RCM. The little Ruger 338 RCM is a wonderful package but I want a light levergun in the winchester 94 because it will provide the performance i need and expect.

What or where is a good heavy mould to get for this 38-55? What about bullet diameter on the legendary frontiersman?–

This is my heavy for the 38-55 Legendary Frontiersman from "Accurate Molds" Tom does a great job producing excellent molds that drop to your exact specs..

I cast this one heavy at 30:1 alloy and order spec diameter .382 sizing to .380..Gas checked and lubed it weighs 320 grs & is very accurate at a tad under 1400 fps

No pressure issues so far with this load of 5744 and mag primers hoping to bump this up some to 1500 fps if it continues to behave..

L to R 275 & 320 grs[Linked Image from i.postimg.cc]

I highly recommend Sage "gators" for either of these bullets.

Dennis made some of his Truncated Cone 35cal bullets in 230gr for me in the past.

Man, all this talk is making me want to buy the pre safety Big Bore 94 .375 the LGS has for sale. Have been holding out for a decent pre-64 in .38-55, but I ain't getting any younger.
