Default 17 hornet observation

reloading the 17 hornet seems to be straight forward as cartridges go. I did notice one oddity, it's a good thing it's a rimed case. factory loaded cartridges are .011 shorter at the shoulder than a fired case, reloaded cases are within .001 of fired cases.

makes you ask the question why do some rifles shoot factory ammo in a 17 hornet light out? sure wouldn't like to worry about case life if the shoulder was to be pushed back on a regular basis.

just my rambling thoughts.

I think the issue is the different chambers being used in different rifles. Don't have a 17 Hornet but have four 22 Hornets, and their chambers vary widely. The Ruger No.3 is huge/sloppy and the Kimber M82 is pretty tight. The Ruger gets 3 reloads before annealing, while the Kimber can make it to 15+ reloads until it needs annealing. I neck size only, and segregate the brass to the rifle.

I'm surprised they don't split at the web, with .011" slop between the base and the shoulder.

I went 14 loads, neck sized only and crimped, in my CZ.22 Hornet, TinMan, then necked them to .17 and fired 3 more times THEN had to anneal, when using RP brass.
The new Win brass I necked to .17 needed annealing in .17AH after 3shots, including FF. Thus, chamber size and shape sure makes a difference. The CZ and the Ruger #1 had
very tight chambers in neck diameter and case length.

Nature of the rimmed/belted design, it headspaces off the rim or belt, not the shoulder. Undersized by a bunch, shallow tapers, maybe chambering in a dirty rifle was a design criteria?

.011" ain't nuttin', try a 303 Brit.

I've been shooting Hornets since 1968 & loading for wildcats since 1978. I have
an idea about headspacing. I am also aware that many .303's sepearte on the second
or third loading, same as .300 & 7mm. Mags. when people rely up on the
rim or belt for headspacing.
I also know the Hornet brass is the weakest brass made today in CF.
I also know that .22 Hornets with that much slop - as in my first .22 Hornet
BRNO separated at the web with .012" slop, shoulder to base on factory ammo,
but 0.003" on the rim.

i guess the question should be is the factory ammo length correct or is the cz chamber length correct? I set the die to touch the shell holder and cam over and the shoulder is pushed back .001, that said I guess I could have turned it on down and pushed the shoulder back another .010.

I would trust the chamber/die measurement more than the length of a factory case. If the factory case is/was true, then your dies are way out.
The headspace on a factory rimless case is only .006/7", CIP and SAAMI. You could always sacrifice a case and section a fired factory case to see
if it is stretching at the web.
