One way to find out. Someone send me a hmr barrel lol
Is there a Canadian source for a .17 HMR barrel and magazine and whatever else is required for the conversion for my 455 Standard?
might be faster with the shorter barrel........unless your burning powder all the way to the muzzle your just adding bullet friction, funny thin with rimfires is that they perform better with shorter barrels, but we are brainwashed into believing longer barrels are better......and for open sites that hold true due to the longer sight picture, not so much for velocity and accuracy
Varmint Al did a velocity/barrel lenght test,22" was 2517fps, a 17" barrel was 2505fps, and a 15" was 2477fps. Velocity dropped from there. 10" was 2276.
I just ordered a 455 American 22lr/17 hmr combo and should be here on Tuesday they come with 2 barrels with 1 mag each.
I will post picture when it comes in.
I'd be interested in seeing how they dealt with the difference in rim diameter and thickness between the two cartridges.
The common wisdom (which, often enough is based on belief more than facts) says that the two would not be compatible.
Flat faced bolt and a rim recess in the face of the chamber? That seems to be one possible. Or ???
Pretty interested in seeing a close up of the bolt face and chamber end of the barrels.

Got mine today! It came with the .22lR barrel mounted so I'll be trying it first, but most likely be keeping it as a .17HMR beaver tool. I cleaned out all the shipping grease and CLP'd everything. Installed the yodave trigger kit and +10 striker spring. And mounted up a 4-12 vortex viper on leupold rings.... Just need to go shoot it!
All I have is the 50m factory targets for now. Not all too inspiring at about an inch for both the .22LR and the .17HMR.

Sorry for the poor phone pics!
CZ targets are done for function only not for anything else.You won't be disappointed at at all after you shoot it.

Make sure you break the 17hmr in like a center fire as it has a jacketed bullet. Lilja covers that in the tech dept.

I bought one... 'Should arrive on Thurs.
Why? They are hammer forged and hand lapped barrels. I just cleaned mine and shot it. Shoots moa easily.
Can only tell you what lilja says I don't think any one would not take heed to their advice.
Read attached at the bottom paragraph about win mag and 17 hmr as it applies to those. Hope this answers your comment as to why.
