In the Hornady Handbook of Cartridge Reloading Fifth Edition,
The section on the 375 H&H magnum mentions data for the 220-225 grain bullets.In this section it gives data for a reduced loads velocity 2000 ft per sec - 2400 ft. per sec.
Powders used SR 4759, H 227 & AA5744.
Have any of you had experience with these loads with reduced velocity?
How has your experience compared to the velocity in the 2500
FPS to 2800 FPS(feet per second)

Reduced loads in the .375 H&H are more practical and fun to shoot for most North American game.

A load which I have used with great satisfaction for eastern deer hunting in the woods is the Ideal #375449 cast no harder than wheelweights, shot without the gascheck, tumbled inLee Liquid Alox and sized .377", using 13-14 grains of PB, Red Dot or SR-7625 shotshell powder. Its ballistics approximate the blackpowder .38-55 Winchester, about 1300 f.p.s. in a 26" barrel and 1200 f.p.s. in a 23".

If the standing bar of your open sights is zeroed for 300-gr. factory loads at 200 yards, this one will shoot on the money at 50 yards with the same sight setting and it is very accurate, capable of one-hole groups at 50 yards and under 1-1/2" with hunting sights at 100. Lots of fun to shoot and a good training load. A friend in South Africa has killed hundreds of head of deer sized plains game from impala and bushbuck to kudu to fill meat contracts for biltong using this load.

Hi Ed:
I certainly appreciated your post about shooting cast bullets
in my 375 H&H mag.I don't have a lub Sizer yet but this may be the incetive to get one as I have a 45-70 that I could use it for as well.
Many thanks.

Save your money and just get the Lee sizing die kit. This has a "push-through" style bullet sizer with 7/8-14 thread which you put in your regular reloading press, and a base punch which fits into your shell holder ram. Cost is about $15. Keep the loads below 1400 f.p.s. and save the money by not bothering with gaschecks. Cast the bullets fairly soft, about 10-12 BHN and they will expand some. Very pleasant, accurate and cheap to shoot, effective on deer up to 100 yards and you won't wear out your barrel.

Hi Ed:
I just wanted to say thanks for your reply.I may follow your advise on the Lee Sizer kit.However, I found an old Lyman
45 at the local gunshow for $7.00.It appears to be all there but is gummed up with old lube that has hardened over the years. I plan to put the lower part of the lube sizer in the over and set heat on about 175 degrees and see if I can't get the old lube to drain out.If this doesn't work, I will use the Lee kit as you suggested.
Also, I found an old Ideal lube sizer with three dies for $5.00
The dies are not the right size for my use but I may be able to work out a trade with some of the folks in my rifle & pistol club.

To clean a lubersizer, I boil them in water. It works great! I did this with an Ideal (1st model) and Lyman (gray) and they look like new. Paint does not come off either. I coated them with Super Lube.

I had the same questions loading lead in my Win. 70,Super Express 375 H&H. Thanks for your answers. I bought the 375 recently because it was a bargain and after reading several posts, I think it will stay in my humble collection.
