What do you think about converting a CZ in 17HMR into the new 17 winchester super magnum?

Possibility or too far out?

Without knowing the magazine specs on the CZ and the OAL on the 17 Win. this is more of just an observation, but it looks to me like the 17 Win. is a quite a bit longer than the 17HMR.

It's a larger diameter case. I would imagine your rifle would need to have the bolt face enlarged to accommodate it.

I think it's too long to fit in the magazines designed for the 17 HMR and the 22 mag.

Also the body has a larger diameter which means the case head is also larger. That means the firing pin strike won't be in the correct location for the larger case. It would strike more towards the center instead of the rim. The bolt face and extractors will be screwed up too.

All of that aside, does these existing 17HMR and 22 mag actions have the length to accommodate the longer case? It's more than just sticking a longer magazine under the rifle.


22 LR, 22 Mag, 17HMR and the two on the right are the new 17WSM.

To me at least all of this means the manufacturers are going to make completely new rifles or major adaptions to existing rifles to allow them to fire this round. If there isn't an industry wide acceptance of this cartridge with most manufactures producing a nice varity of rifles for it, it's future will be in doubt. Then you will have to order your ammo thru retailers who also stock 5mm rem mag.

I think the key to widespread acceptance will be the cost of rifles chambered for it. If its in the same price range of other mass produced rim fires it will be a hit. The success of the 17 WSM will depend on Marlin, Savage and CZ. If it takes Centerfire money to buy one it won't do as well.

If the new case is commercially successful, we could see a whole new series on rim fires. I'm thinking a 22 WSM, 20 WSM, maybe even a .243 diameter? It could be the start of something revolutionary in rim fire performance.

Personally, if things get too extreme in the rimfire world, I think rimfire only zones will rewrite their codes, negating the benefit.

For the rest of us that can use centerfires, why do I need a rimfire that can do what my centerfires do?

I think your in part correct. I think the price of admission to the show is going to cost more than your average rimfire rifle though. The higher performing rifle is going to demand more money upfront. Especially if new rifles have to be built to accommodate the cartridge. Which wasn't the case when the HMR came out because it simply run off a 22 mag action.

Support for the cartridge needs to be two fold, budget rifles and some higher quality stuff like the CZ, Ruger, Winchester and maybe a Browning. I know several who won't buy if it up to Marlin and Salvage to carry the load.

Considering the price of brass and in particular scrap brass its doubtful. Revolutionary would be some way to collect and recycle all the brass that otherwise gets left on the ground.

I don't know anything about rim fire only zones, we don't have them in Maine. The manufacture of new guns and new calibers stopped being about need a long time ago. I don't think any rim fire will be replacing center fires anytime soon, but it doesn't mean I don't want a better performing rimfire.I'm kinda excited about the prospects.

Sorry, I don't understand how that affects the sale of new calibers. As far as recycling the brass, all one has to do is bend over and pick it up. I've been doing it for years.

Wait til you see the cost of ammo...then it might be more clear.

You may be right, but what ammo isn't expensive nowadays?
