I have a new Ruger .375 Ruger I'll be reloading for, now that unfired
brass is on the way. Bullets I have are 200 gr. Sierra RN, 235 Speer
SPFB (the old original .375 H&H one), 270 gr. Hornady SP, and 300 gr.
Barnes Spitzer SP (the old original .375 H&H one).

My question is whether I can apply the reloading data for .375 H&H
with my .375 Ruger, using the same bullet? Basically, the Ruger case
holds 6% more, so I'm figuring this would be a safety hedge against
over-loading. I'm interested in reduced loads, not high pressures.

Here's what I find when I look for a comparison of loads for the H&H
and Ruger for the same 235 Speer SPFB bullet, powder, and primer,
arriving at about the same fps. (from the site at
http://www.realguns.com/archives/144.htm).

H&H: 3.600" 86.7 IMR 4895 77.5 CCI 250 3115
5065 1.0
Ruger: 3.255" 90.2 IMR 4895 79.5 CCI 250 3195
5328 0.6

Probably the posting format will skew my columns, so I won't try to
provide headers.

Thanks for any comments on the usefulness of trying to use the older
H&H loading data for my Ruger. Not sure if the powders have stayed
the same. bookburn

Sure, you can use data from other calibers, but you'd be foolhardy to
start with direct use. Experienced reloaders always advise to work up
your loads beginning with reduced loads. Good luck.

Go to Hodgden's website, obtain their toll free 800 # and give them a
call. Chances are good they can give you some recent data for the
375.

Thanks, I'm behind on my hand loading homework, although I now have
everything to get started, except hearing muffs for the range, when it
gets warmer.

I did send away for " Ken Water's "Update .375 Magnum - Pet Loads," in
Handloader 200 (August 1999), 50-54, which give 3-5 of his best loads
for 235-300 gr. bullets, including the old 235 Speer semispitzer and
270 Hornady Spire Point, which I have. Still looking for a favorite
load for the old 300 gr. Barnes Spitzer Soft Point.

BTW, in the above article some of the most accurate are, in order:
300 Nosler Partition, W-760, 74.0, 2,470
300 Hornady Roundnose, H-4895, 66.0, 2,387
300 Hornady Roundnose, H-4831, 82.0, 2,455
270 Hornady Spirepoint, RL-19, 78.0, 2,593
270 Hornady Roundnose, W-760, 78.0, 2,593
All I can deduce from this is that the larger grain bullets do better,
disproving the argument that faster bullets are more accurate. What
I've read about the roundnose bullets suggest they do better at
shorter distances than boattails and spitzers.

With luck, I'll get an Internet clue from someone reloading for the
..375 Ruger on how well these old H&H favorite loads will work out.

look for that.

This article confirms that (quote)
The shorter powder column utilizes powder differently, or what is
commonly termed �more efficiently,� so charges are similar and
sometimes less (especially with heavier bullets) in the .375 Ruger
than the .375 H&H. (unquote), and says performance on game should be
no practical difference between H&H and Ruger. Too bad the chart
listing loads doesn't indicate accuracy.

This article shows a long list of loadings, including accuracy, but
for some reason doesn't include any 200 gr., 270 gr., or the Barnes
300 grain, which are bullets I have.

Both sites develop info for model with longer barrel than my 20"
Alaskan, so would have to factor that in. Possibly I can use the
Internet site at AmmoGuideInteractive as a guide?
