Guys, this was a little bit of a boo boo on my behalf, i referred to an older reloading manual from the Powder company an made a decision on a grain up from the Min/starting load- which was 28gr of powder.( max of 30gr)
I just today looking online at the latest loads an the min load is now 31 for the same powder.

The stated velocity is

older version- 1900fps for the max load 30gr,
new versions- min 31gr @ 2050fps and max 34gr @ 2200

So i figure im really low in Velocity..... Im using Hornady 220gr an word on the street is this isnt enough velocity for expansion?

Whats your thoughts?

W/L
 
Thanks for your input dan, The .375win hasnt got many followers so is hard to get first hand opinions, i search Google alot an come up with various threads from various forums of which im not a memeber an threads are sometimes, years old.

Ive noticed n CGNs its slowly picking up a handful of followers.


Its easy to read a stated Velocity of high 22-2300s with reloads, guys wanting to push the cartridge to its redzone... sometimes i get a little confused an want higher numbers for my rounds but it isnt needed.

Once i blow a few of these rounds away i will have to, out of curiosity load a few hotter rounds an see what happens!

the 38-55 killed Bison, deers Moose and bears for years.....

Any further input / discussion is appreciated
 
The bullet is large enough to kill without expansion. You may have to trail a bit further though.
You didn't specify the bullet other than Hornady 220gr.
so I'll assume this one:

Features:


  • Aerodynamic secant ogive delivers flat trajectories and great accuracy.
  • Tapered jacket for deep penetration and controlled expansion.
  • InterLock ring locks core and jacket together.
  • Lead alloy core is tough enough for any game.

Item Number3705
Weight 3.29 lbs
Ballistic Coefficient (G1)0.217
Sectional Density0.223


Just to eliminate confusion, the actual bullet is the TOP one pictured, not the cutaway, it's just there to show construction.
I've had good luck with interlocks for many years, in fact I can't think of a failure.

I suggest you sight in for the load you are using, the trajectory will also be different.
 
Yeah mate, hornday 220 interlock bullet.

Yeah i shot at 100 with a factory 200gr Winchester superX round an it hit spot on centre of the 5 or so inch circle i made to aim at....! i was stoked!

I then shot the 220 reloads of mine, with the Hornady interlocks and was suprised to see the hole much, much lower.... Ive moved the Williams peep sight up a bunch of clicks an started gettin strikes around the 5 inch circle.

I have looked further into the velocity an trajectory, seems the 375 velocitys are much more effective with a flatter trajectory, almost compared to a 30-30 with a 170gr bullet... where as the same cant be said for the slower 38/55 speeds....
 
Usually a modern bullet will expand reliably down to about 1750 fps at impact, depending on the hardness of the core and the thickness of the jacket. IMHO, Hornady cores are a bit harder than they need to be, but they still provide some upset at lower end of the velocity spectrum. The trouble is that no bullet can be all things to all people. The fellow next to you will whine if that bullet is fired out of his .378 Weatherby at 3850 and comes apart on a coastal grizzly . . . he'll have a reason to whine too. Its too bad that all bullet manufacturers didn't recommend a velocity range for their bullets like Woodleigh does. Given the medium-fast burning rate powders you would likely use in the .375, under loading a bit presents no safety issues. Frankly, for low velocity applications, up to say 2000 fps, I would look at cast bullets. A cast bullet with a wide meplat has proven to be a good killer ever since rifling was first put in barrels.

I may have had one Tumble into the box..... what causes tumbling?

il try post a photo tomorow of the target

A bullet that tumbles on impact is a sign of instability. Typically a bullet is in yaw twice during its flight, first when it exits the muzzle and again when it impacts the target. Precession, which is the term for yaw which occurs with contact against a denser than air object, is normally short lived if the rate of spin is sufficient. However, if the bullet does not expand, the center of gravity does not move forward, and the bullet may want to swap ends, as the base is heavier than the nose if the shape is tapered. The best solids are short for caliber and have parallel sides.

Well, for no reason i bought a Bullet mould when i first got the rifle <4 years ago now, its a RCBS 250gr flat nose 2nd hand of a guy.... casting isnt as melt cast shoot though, i need to research

I recently quickly watched a youtube video of a guy melting lead for cast bullets... i have a handful of hornadys left an most will be shot to paper with hopefully one deer in a few months.
it could be an option
 
I have a modern 38-55 [1980 build] in a M94 Winchester.
I have been shooting and loading for it for several years now.

Surprisingly effective, particularly with updated loading data.
It is possible to safely drive the 255 grain Barnes softpoint to 1800 fps
in the 38-55.
I do know that that load drops deer very quickly.

H322, IMR3031, RL7, H/IMR 4198 all work well in mine.

I have shot groups as small as 1" at 100 meters, using a Williams FP and firesight front.
Average is more like 1½" though.

I also shoot several cast bullets. [240gr, 265gr and 285grGC.]
This rifle is very cosmopolitan in it's tastes, and shoots most bullets fine.

However, It keyholes the .375" 220 grain Hornady, probably due to the fact that my groove diameter is .3774"

Bit of an Update-
Got a Factory Crimp die an crimped all my loaded cases, grabbed a few this arvo an shot down range at 100ms, glad to say i can hit a "shoebox" sizebox open sight 100ms with my "slow" reloads, Williams peep sight an 220 hornadys crimped!

Been a few years in the making but my love child is finally ready for proper hunting an no hit an miss accuracy... seems to be consistant enough for a still huntin gun!


PS- ya mighta seen i just purchased a No1 303br, which in most cases will get priority over the 375 for this style huntin... til then tho!


Cheers

Even sedate loads will put down a deer if you hit something big, but there is no massive shockwave to put an animal down with a margin hit.
Cast bullets with a big Meplat are still pretty potent.
 
Can i just add to this thread, My loads of 375winchester at warm 38-55 velocitys works Fine!!

The shot was alittle under 100ms.
* i had photos of entry & showing exit + blood loss but will hold out.
the entry is about 3inches NW of that blade a grass near the stock, bullet exited rear of the guts before the leg muscles. got a bitta lung an appeared to expand some, cant wait for the next one

If I could find a a 375 win or 38-55 that wasn't (or appeared to be) 100 years old, I would soooo own one. I had the opportunity to shoot one last spring, and have been creeping the WEB for one ever since.
 
The .375 Winchester is an ideal caliber for critters weighing anywhere from a few pounds to
1500 plus. The key is to place the pill where it will drop the game with quick certanty.
A cast lead bullet in the 220-260 gr. range will do the job on game at 1400-1700fps.,provided
that the shot is properly placed on target within 150 yds. or less. For my own shooting, I
prefer to stay under 100 yds. for the bigger game.
