I have a lot of old American Riflemam that I have been buying up as found, and as mentioned last month really enjoy any articles that were written by C.E. Harris. In that light, Col. E.H. Harrison was also a great technical writer and I hope to one day find and purchase at a reasonable price his book Cast Bullets. I believe that C.E. Harris was a major contributor as well to that book.

Anyway, just curious. When did Col. Harrison retire? Is there much biographical information regarding him?

Thanks, Vacek

Thank you, Larry, for the data. Please excuse the delay. I thought I had replied.

Hi, Larry.

Thank you for your response.

I dug out a Lyman Cast Bullet Handbook, 3rd Ed, 1980 (presumed lost in the move) that has several reduced loads for .22 Hornet that give velocities slightly higher than your Bullseye loads.

In a Win M54, 24" bbl, 1-16", 0.223 groove dia, Lyman used #225438, wt. 41 gr and RD, 2.0 gr @ 1095 fps to Unique, 3.0 gr @ 1365 fps.

I don't want to get into casting again, so I'll find cast bullets online. I've got online BO's for additional reloading presses to speed up the process since I'm a single stage guy. I plan to use the Lee hand tool to spend a pleasant afternoon working up reduced loads for accuracy, starting with yours.

Best wishes,

Jack from PA

I'm sure you know this, but I wanted to post it for the other members. The older I get, the more cautious I get when tinkering with very reduced loads, thinking of the Bullseye accidents over the years.

I pulled out my slide rule recently and found it was trashed from foolishly leaving it in the leather case - the frames for the lenses were rusted to pieces.

The reason the slide served so long and so well is because with a few exceptions, we only know the magnitude of most things to 2 significant figures. Strength of any material used used in designs, almost all loads that the things we designed will have tho handle, etc. -- all known to only two figures if you are lucky. So you can carry out your calculations to three figures with a slide rule or ten if you like with a computer but the physical world won't care and your design won't be any closer to right. There are exceptions of course that's why there were the hated log tables.

Joe,

Good call. Of course there were computers since the 1940's but many great things that needed calculation used the humble slide rule and the human brain prior to the mass use of computers. I'm sure that there was always some "extra" put in where as today, gnats whiskers are the dimensions that a computer can calculate. Burroughs and VAX mainframes were the standard college computer when I was an undergrad. A few DEC CMP machines and eventually IBM PC's started getting on desks in the 1980's.

Everything prior to 1975 including the Saturn V and the Moon landing was handled with slide rules and three significant digits. Battleships, skyscrapers, trans ocean flights, V2 missiles, jet engines, bridges, Detroit V8's, the list goes on. Computers made the data retrieval and storage easier. The math is the same, now it is a machine that does the heavy lifting and not your brain. Games, Porn and ideas that make you want to agree with is what computers have brought to us. Don't get me wrong, I use one every day (right now) but dang I really miss writing those heart felt letters and cards and the brain needs some work to do. Hey what about the chronometer and the sextant? Just rambling.

You forget the DEC computers such as the PDP 8, lotsa them sold to manufacturing companies.

I bought printed circuit board drills, insertion machines and sequencers in 1969, all N/C; programmed on Friden Flexowriters on 8 channel EIA tape- computers were GE.

Before that, ~1965, programmed machine tools on a Borroughs ?E101B?

Days of interpolating the circle.

Larry, Sweet setup. Thank you for the information. Is your twist 1:14 inches? I've not measured mine, but presumably it's 1:16. The Handi Gun II is not particularly accurate but is loads of fun and quite "handy." Jack

Both the 21" and 10" Contenders have a 12" twist. Older ones may have 14" twists as per older Lyman Manuals. Those loads also shoot very well in my 14" twist Savage M40. The 225428 bullet also did very well in my 16" twist #3 and the older Savage M23s. The 225415 load did ok to 50 yards+ but lost stability/accuracy around 75 yards.

Dave,

If you want a good read on how powerful a slide rule is, pick up a copy of Yeager! The general tells how he needed to depart a short field in a Century Series (sic) fighter. His flt eng, Jack Ridley did the takeoff calculation and put his jacket on the side of the runway. He told Yeager to punch the burner when he got to the jacket, and he would have 10 feet to spare. It worked, and Yeager trusted him implicitly after that. (From memory). Pure genius.

Did anyone here know Jack Ridley?

I used to be adequate with a slide rule. It might be time to get reacquainted.

Best wishes, Jack

Let's not forget logarithms, the easy way to multiply big numbers by addition or divide by subtraction. One more significant figure than a slide rule if you interpolated correctly.

My college had a professor who each summer sought and received another doctorate. He wrote programs for the challenge and was a good source for physical chemistry card packs to run backing up our senior experiments. Great resource, his programs ran the first time every time.

One student miswrote a card set and shut down the core processing unit of an IBM 360 servicing five colleges in Western Illinois and Eastern Iowa.

When I was at Ruger state of the art was a 2-suiter sized IBM "luggable" used to program 8-inch Wang disks used in the Boston Digital and North American Rockwell machining centers, being replaced by Hitachi-Seiki in the late 19 80s when I left.

Like Ed I had to make a card program to do the ME experiment calculations at VT - took quite a while to get it right and run the program for results. Lots of fun ?? Finally got out!

"Since I have you captive, would you have any "cat sneeze" loads for .22 Hornet? I've a nice little H&R Handi-Gun II, that I'd like to use as a Rook rifle."

Not Ed but I have a couple real good subsonic loads I use in both my 10" Contender and my 22 Hornet rifles (over the years in a Contender 21" barrel, Ruger #3, several Savage 23s and a couple others).

Lyman 225248, GC'd, lubed with 50/50 or 2500+, sized .225 loaded over 1.8 gr Bullseye in W-W cases with WSP primers. Runs right at 1100 fps.

Lyman 225415, GC'd, lubed with 50/50 or 2500+, sized .225 loaded over the same 1.8 gr Bullseye in W-W cases with WSP primers. Runs right at 1050 fps.

I cast them soft with COWWs +2% tin mixed 50/50 with lead or with 20-1 alloy.

Accuracy is excellent and the 225415 thumps ground squirrels as hard as does any 22LT HV HP. With the suppressor they are quieter tan my pellet rifles.

Howdy, Ed.

Thanks for the information on Col. Harrison. I thoroughly enjoyed his expertise and writing. Still have some old NRA books with his articles.

Btw, my uncle Stan was a Gobbler football standout in the early 1940's, I believe. After he was drafted he developed testicular cancer and died from radiation treatments at Brooke Army Medical Hospital at Ft Sam Houston, 1947. As told to me by my Father, a WW2 flyer, B-26.

Since I have you captive, would you have any "cat sneeze" loads for .22 Hornet? I've a nice little H&R Handi-Gun II, that I'd like to use as a Rook rifle.

Sincerely,

Jack M Altoona PA
