20 Hornet

[Bill73]

Anyone have actual velocities with 32 grain bullets in 19 or 20 Hornets? Is 3200 fps reasonable?

My 17 Hornady will push 25 trainers to 3200-3250 fps ....

Yeah nah no way......

Bill73..... how long of a barrel for that 3553 FPS speed? What OAL are you loading to?
Thx

Standard PTG 20 Hornady Hornet chamber, 21 inch barrel, no long barrel required with Lil gun. OAL 1.780.

I have some Power Pro 300MP to test soon which may allow me to crack 3600fps......

I managed to push 40gr BT to 3135fps but the accuracy node was back at 3000fps.

I have a 17 Hornet and a 22 Hornet. I'm covered.. 20 Hornet doesn't interest me. IMO there are other 20 cals that are much better..

If the .17 Hornet was for a 4 lb 'chuck and the 22 Hornet for a 12-lb 'chuck - I'm guessing you need the .20 to whack an 8 lb 'chuck? One has to have all the bases covered.....

had a tool maker open up my 17 Hornet dies to 20 cal, took a bit longer than ideal but that's the year we've been having.

Nosler appear to not anneal their hornet brass and primer pockets are a bit average too. I cracked a lot of brass in the first batch of fireforming but a butane torch fixed that issue. shot my first batch yesterday at the range.

A light load of 10.8gr Power Pro 300 pushed the 35gr Berger to 3020fps. With the cases now formed Ive got plenty of testing in the coming month.

Any one convert from 17 Hornet (whether Ackley or Hornady) to 19 or 20 Hornet? Or if you ve shot/got both?

My 17 Hornet is over 4K on round count and another season or two might be time for a change. Rifle is Ruger 77 so looking at staying with Hornet case as that's what rotary Mag is setup for. The 19 sounds interesting BUT only Calhoun has bullets so 20 might offer more choices.

Questions:

Is 20 more forgiving on cleaning and fouling?

Do you neck up 17 Brass to 20 caliber? Or, do you fire form from 22 Hornet which is much more work I assume.

What bullet weights and powders are optimum for the Hornet based case? (45K psi or so...) what twist rate and barrel length?

Other input and experiences?
Thanks for your responses.

I have purchased a CZ 527 Varmint in .17 Hornet.
My 1st in any 17 Caliber.
I have purchased a Timney Trigger set at 2 lb. as a replacement for the Set Trigger,
For my particular CZ527, Timney's CZ550 trigger works.
Now, I am looking for a Trigger Shoe to go with it.

Now, I am looking for a Trigger Shoe to go with it.

Are you thinking something business attire like a wingtip or more sport casual like a loafer.
