.375 reduced loads
book...@yahoo.com
..375 Ruger. Going into hand loading is logical, because ammo is
expensive and a problem to get, and this gun has a 20" barrel, weighs
about 9lbs. with Nikon Monark scope, and the .375 Ruger case is 6%
larger and a little more efficient than the .375 H&H. So I have some
differences to work with and will be starting with reduced loads.
My beginning strategy is to get the brass and load some Sierra 200 gr.
FN I have, trying for something accurate and okay for deer and target
practice. Then I'll try to use some favorite loads of the great, old
..375 H&H shared by fans over the years; maybe try reducing them by 10%
as a benchmark or go to another powder and/or primer. To do this,
I've used my library card for an interlibrary loan to have copied off
a recommended article that appeared in Handloader Magazine, back in
August of 1999, on "The .375 Reconsidered."
This is going to be a fun winter's project for me.
Happy New Year, bookburn

You would be well advised to find a good mold and cast some bullets for that
one. You can drive cast bullets hard enough to satisfy your desire for a good
solid recoil, and the chances are very good that you will get good accuracy too.
No deer will survive a decent hit with a cast bullet in .375, either. Lyman
offered a dozen or more molds for the 375 at one time, and you might find one at
a gun show, or on eBay - you never know. Lee offers a 250 grain mold even today.
Fine caliber, enjoy!

Thanks. As it happens, I found an inexpensive supply of good stuff,
like Barnes 300s, from a private local selling everything. So it
goes.

I use 40 grains of SR4759 with either the 200 grain Sierra or 220
grain Hornady flat points in the 375 H&H, for about 2200 fps. I
believe I got this load from the Hornady manual, but I don't remember
for sure. All but one of the 5 or so deer I have killed were with
this load. Every one was a bang-flop, with complete penetration and
big exit holes. Back when SR4759 was discontinued, I bought every
stray can I ran across in gun shops, just to support this load.
True story: One deer season years ago, when my eyesight and nerves
were better, I went to the range to test fire my rifle and the SR4759
loads. I put 4 rounds through a nearly circular hole at 100 yards
from off the bench. I didn't have the heart to fire a fifth round...

about 1700 fps. AA8700 is a great powder for reduced loads as it is slow
and bulky. More than likely you are going to have some unburnt powder left.
This could be cleaned up if you use a duplex load (BE VERY CAREFUL) with a
pistol powder such as Bullseye. This also will solve problems with erratic
ignition should you experience it. Remember this is strictly for reduced
loads. There is no working up with this powder in the 375 Ruger as you
would be using the full capacity of the case. With such very low pressure
loads make sure you do not end up with a squib and a bullet stuck in the
barrel.
You can also use faster powders like SR4759 (about 30 gr.) but you will also
increase pressure as well.
I have heard of some using trail boss but never done it myself with a rifle
cartridge.
Good luck.

I see one load for the 200 grain Sierra FN using 73.2 gr. IMR 4320,
getting 3,000 fps. Another one ups that to almost 3,200 fps. But
assuming that accuracy isn't necessarily a function of speed, and low
recoil is nice, I'm looking for something in your ball pack, it seems.
Question: do you use a filler with the 40 gr.?

Is there a general rule about working up loads, including reduced
ones, concerning using the same primer? It would be easy to separate
ammo on the basis of primers, if you could use regular for reduced
loads, large and magnum for others.

use AA8700 in the 375 H&H you definitly do not have to worry about this as
the pressure generated is way to low (=or< 30;000 PSI). However if you
choose to use a fast burning powder for a reduced load than the answer is
yes. Due to the nature of the AA8700 and the case capacity you will
invariably (re. absolute must) use a magnum rifle primer; if you use a
standard rifle primer be ready for some hangfires or worse a stuck bullet in
the chamber. If you use AA8700 (with a MRP) expect half the powder used to
be unburnt hence the use of a duplex load to help burn out the AA8700
powder. Keep a can of compressed air to blow out the powder if it spills
into the action or barrel expecially if you have a blaind magazine
If you use a fast burning powder such as I mentioned in the earlier post
than you can do well with a standard rifle primer. Also with faster powders
you will not need a duplex load as it will more than likely burn clean. But
you pressures will be high and you will need to work up a load (from about
28gr - 32 gr. for SR4759).
If you use cast bullets you will want to give your rifle a good cleaning
before you shoot jacketed bullets as you may lead the barrel. If uncleaned
a leaded barrel will cause increased pressures and thereby act as an
obstruction in the barrel.
