Ruger 77/20 Hornet



Log in to see fewer ads
Alway wanted a 20 cal and this thing just fell together in the last few weeks after I discovered a buddy had a PTG 20 Hornet reamer ( 20 Hornady Hornet, straight necked up 17 Hornet).

Ruger 77/17 action, Volquartsen trigger sear, Lumley arms Bolt knob, lightened trigger spring, T3X Soft touch forend, 20inch Stainless 1:8 twist barrel, kept the profile the same as the 17 Hornet just added 1mm.

Hoping for a range session next week

That should be a really good round. I believe the 20 will turn out to be a very effective and accurate varmint round for you. I like the 20 better than 17 caliber. I never cared for the 17 Remington years ago that I had or any of the HMR's that I owned. Always wished the HMR would have been a 20 like the 5 MM Remington. Lots of folks like the HMR but I like how the 22 magnum anchors bigger varmints better with fewer crawl offs.

hey bandit I already have a couple of 17 WSMs and they are cheap to shoot and deadly out to 200. Anyway I picked up this 17 Hornet just to see what it had and whilst its accurate I didn't get a chance to shoot anything with it but after seeing a few article about 20 K hornets I realized knock down power going from a 17 to 20 cal actually increased on game punishment by 50 % it was game over for the 17 Hornet

The .17 Rem has a huge case that you can never take advantage of. I prefer the other .17s for sure the .17H can hit 3,650 fps factory while the big .17 Rem wasn’t that much faster. Ridiculous imo. Brass was twice the price & almost twice the size. Small difference in performance.

Ledslnger plan is to de temper and open up the Hornady 17 Hornet dies. Ive got a 204 expander to replace the 17 expander, will be visiting a Die maker next week.

these 20 Hornet cases were made from once fired FLS S&B 17 Hornet cases, 204 R dies were used to open up the necks with a single pass.

I then used RCBS 218 Bee dies to load a pill. I just wound the dies down til they were touching the shoulder keeping it nicely centered and snug, I then adjusted the seating depth to suit and loaded up 4 diff pills.

Im sure 223 dies could be used

Always said that if Ruger put out a 20 caliber on a 77/22 platform Id be on it like my brother in law on the last pork chop. Never cared for any of the .17 stuff. Big fan of the platform. Have multiple 77s in all the 22 cal. All have been sent to CPC for the full combo and all are a great deal of fun to shoot.

A mod Ive been making to my Rugers for the last 18 months is the addition of a Tikka T3X soft touch varmint forend. An extra hole near the magazine and these they slip straight onto the Ruger stock giving it a better more solid varmint forend.

Pulled some more 17 cal projectiles from 3 bxs of 17 Hornet ammo.

Itching to get this to the range.

finally picked up the hornady 20 cal expander and gave it a quick polish with wet n dry paper just to help things along. replaced the 17 expander with the 20 expander in the 17 hornet dies, gave the inside of the neck a quick cotton bud swipe with 1 shot and a light chamfer, and it worked.

59 from 60 case, lost just 1 case so pretty happy.

Day off tmw, so loading up some Lil Gun and various 32gr projectiles for my first range session, hopefully its not too windy.

Have you given any thought to using the Hornady 24gr NTX bullet in your 20HH? https://www.hornady.com/bullets/rifl...4-24-gr-ntx#!/

For a case as small as the little Hornet, I think a lighter bullet, like the Hornady 24gr NTX, would be a better fit than the heavier 32 grainers.

To neck them up to .204 it may be a better plan to use an expander mandrel like the one from KM. https://kmshooting.com/product-categ...eck-expanding/ I've been using these for years and I think they produce a better, more consistently uniform neck, than using a sizing button.

For sizing, to get the desired neck tension, you may be able to use a Redding or Wilson 17HH bushing neck sizing die with the appropriate size bushings. I say "bushings" because 17 Hornet brass has a lot of variance in neck thickness.

The only snag I can potentially see in using a 17HH bushing neck sizing die is if the die, being for a 17HH, may size the neck down before it gets to the bushing part of the die.

I have a Redding 17HH bushing neck sizing die I use for reloading my 17HH. I'll go neck a piece of brass up to .204 then run it through my bushing die, without a bushing in it, and see if it necks it back down below .204. If it does, you could always have the that portion of the die honed out a little.

I've got a couple CZ 527 17HH rifles, they a great little rifle and a lot of fun to shoot, but I've always wanted to rebarrel on of them to a 20HH and shoot that 24gr NTX.

I'm interested in hearing how things go for you 20HH project.

I went and necked a piece of 17HH brass up to .204 then I ran that piece of brass through my Redding bushing neck sizing die with no bushing in it. As I was afraid of, with it being a 17HH die, the neck transition area of the die before the brass goes into the bushing is a bit to tight and sized it back down under .204.

If a person wanted to go this route and use a 17HH bushing die for a 20HH, the die would need to be opened up in that area, but it would be a pretty easy fix and you'd have the benefit of being able to control exact neck tension on all your brass.
