KHornet Chamber Question

[bisley11]

Thinking of having a CZ 22Hornet chambered for the K variety. Would a "tight" minimum spec chamber be the way to go? Some guys at the range say it doesn't matter and some tell me to go to a smith with a tight reamer. Any advice -opinions would be appreciated. :-\

bisley11, I have the K-Hornet reamer for the CZ if you would like to rent it. If you purchase a sami-spec K-Hornet reamer it will not fit in the CZ.
I had to send the sami-spec reamer I purchased back to have it reground to fit the CZ. The barrell is .223 and not .224. I have shot .223 & .224 bullets through my CZ finding no difference in accuracy. Using Lil'Gun powder and 40 gr bullets, I get a muzzle velocity of 3000 fps. Average five shot group size is 1/2 inch at 100 yds. That's average. To answer your question on a tight chamber, in my opinion, I wouldn't do it. What's the purpose unless you are using it for benchrest competition. The K-Hornet is a great ground squirrel (gopher) round. I have fired 350 rds through my rifle on gopher shoots without cleaning, come back to the range and POI and group size has not changed. I love it.

Dave,

Thanks much for providing the great info regarding the CZ Hornet. Sure didn't know the bore measures .223. I'm trying to use a little inductive reasoning. If the sami-spec reamer won't fit the CZ chamber I gather the CZ chamber is on the tight side. My CZ is already MOS accurate consistently out to 150 and probably better in front of a shooter with a steadier hold. Now I'm thinking "If it aint broke......". The K looks so much better though. Will remember your kind offer of reamer rental if I do break down to temptation and K the rifle. All the best and thanks again for your response.

Ivan,

Yes, the K-Hornet does look better but I think the only real advantage is the extended case life. The reason I went to the K-Hornet is because I had two Hornets and I didn't want to mix the brass from one Hornet to another. I'm glad I did. I like it.
