Harvey donaldson

Some of you fellers surely read harvs writings from hundred years ago?!!

I was always intrested in his findings.the point of this post,is he used to use 3-4 imr powders,and use the same volume no matter what kind.he would use slower powders for heavier bullets.

Anyhoo,,ive been doing some exhaustive testing with a 9mm,and a 38 super.keeping very good records,both of these guns have numerous accuracy loads,and almost all the best grouping loads,have pretty much the same volume.
4.4 700x-7.3 a7same volume
Clays/hp38/pp/hs6 same volume
Ive been shooting 10mm as well,and i beleave it behaves similar.
Im wondering if the guns prefers a certain volume,and that lays down the most consistant vibrations??

I can't answer your question, but I do still have my copy of "Yours Truly". Donaldson was an interesting man. At one time he was the oldest member of the Corvette Club of America.

Ya,he was a facinating man!
Seems he loved pretty women as well!!!

And never tired of talking about how great he was, and gave Newton all of the ideas for the 25 Krag and 250 Savage, etc., etc.

I don't know of anyone who has actually developed and done any work on the concept, except repeating Donaldson.

You must not know me or Lamar very well. There's this laziness thing with adjusting powder measures when sometimes we don't have to.

 

[RBHarter]

A full case removes air and position variables so yeah volume is a factor in accuracy, consistency, and velocities. But there are other dimensions that don't up the plan like having 27 gr of brass or 10 gr of water volume difference in your 06' cases and suddenly your rifle is throwing shots over there 18" or the 54 gr of 4350 and 150 gr BTSP is clocking 2980 fps MV in a 22" barrel . Yeah been there .

Ive been loading for 35 years or so,but i never kept as precise records,as i have the last 5 years or so.
Ive been finding some of my best accuracy,and easiest to get,by down loading the medium burners.they seem to out shoot the fast burners,at the same speeds.
I run powerpistol,a7,hs6,and wsf,,,way low,,and the guns shoot spendid.
If i was computer savvy,i could graph this stuff,and maybe come to conclusive proof,but im just a backwoods farmboy/piper,,,

He was a huge fan of graphite wads under his jacketed bullets,,aint heard of anyone doing that,in forever!

We all have learned a lot since the 1930's and 40's. Lots of things "sounds logical or should work" that are just not true. Look at how many "moly" coated bullets are available now? Revolver leads? use harder bullets so they don't strip in the barrel.

 

[Mainiac]

I was heavily into centerfire benchrest in the 90,s,and early 2000,s
Thats when the moly crase hit.everybody was doing it,couldnt understand why i didnt jump on the band wagon...meanwhile,i just kept on winning,with naked copper bullets.dont think its even mentioned anymore,but ive been out of it,for many years now.

 

[Tomme boy]

Moly or some other form comes and goes every 10 years or so. Last time it was HBN

Last hurrah for them was the 80 IIRC, might have been early 90's.

Im thinking i didnt really miss much,from never using them.

 

[JWFilips]

Have a book he signed

 

[Mainiac]

Wonder where his rifles ended up?
And the corvettes?

No, no, that was Elmer Keith that developed and/or invented anything worthwhile related to guns.

If you read the old books and magazines you'll find lots of people claiming to have been in on the ground floor of lots of stuff. Very often, their claims seem to bear out.

From the 1880's through the 1950's people actually wrote letters; pen and ink on paper. Elmer Keith actually wrote more than one letter each day, and Townsend Whelen more than three each day. There was much more thought about shooting when you had to write it out, and not keyboard it onto the internet.

No matter what people think now, nothing was done in the dark for the last 150 years, just slower.
