Well, as much as I hated to do it, I have a new CZ 527 American on it's way to my local FFL. When I say I hated to do it, CZ stopped production on them back in 2021 and since then the price has slowly crept up so now they are almost twice the cost of a new one back in 2021. It has a set trigger on it, that's the big reason why I wanted it, plus it should make a great varmint round for 175 yds or less. Now after doing some reading I see that if I change it to a K Hornet, that will help with the brass longevity. Further reading showed many, variants of the K Hornet. I still have to see what chamber reamers are available, but I see there are at least 4 different variants out there, and NONE are listed in the SAAMI Spec book. loaddata.com/Cartridge/22-K-Hornet-Hornady-Handbook-of-Cartridge-Reloading-7th-Edition/1264I still have to call around to see what dimensions the available chamber reamers are, but which one should I be looking at? |

I had one in a Savage 23D.
I loaded a lot of them with a Lyman 310 tool. 2400 and a 45 grain bullet was the ticket. My brother taught me to reload and in his opinion 2400 and 3031 were the only powders you needed.
When fireforming I used some lead gas check bullets and a light powder charge. I seated the bullet out to engage the rifleing. I never lost a case that way. I would lose a case or two when fireforming from factory ammo. I Anealled every 2 or 3 loadings.
I traded that rifle off on a Browning T-Bolt T2 left handed which I still have.
If you do not have dies you might ask what Chamber Reamer the die makers reccomend. The 310 Dies only neck sizes only so that may have been a factor in brass life.

I think I would see what it does as a Hornet before making it into a K. If I remember there is not that much gain in MV. I have heard Lil Gun is the goto powder in the hornet now. I took the plunge and bought an annealer. I load 25-20 and just starting 219 Zipper so I got tired of the drill and socket method. My first run was 100 Zipper cases I formed from Hornady 25-35 brass. I was happy with the results I got. There are a lot of Youtube videos on making your own to save some bucks. Link to EP Integrations www.epintegrations.com/ |

I have an annealer for my 7mm Allen Magnum, I anneal it every loading to eliminate the splits I was getting at the neck to shoulder junction. I did some searching and the K Hornet is 100-200 fps faster than the regular Hornet, just under .221 Fireball speeds but the biggest advantage is not having to trim the brass every reloading. The shoulder angle minimizes the case stretch and helps the cases last longer too.

FWIW Why not just fire form your brass, trim once and just neck size(don't need a dedicated neck die either, just use a full length backed out a couple thousands) from there on out. I've found I can get a lot of loads from a case , no matter the cartridge, before I have to "bump" the shoulder. this method gets me the more consistent accuracy over full length resizing. Steve |

Steve Steve, if you are talking about the 7mm Allen Magnum, I tried neck sizing but found that I have higher pressure signs doing that than if I bump the shoulder back about .0005". Barely enough to get some resistance the last 50% of the bolt closing cycle. Kirby Allen (the gunsmith who developed the cartridge and who built my gun) recommends FL sizing just enough to get a bit of resistance when closing the bolt. I have yet had to trim the brass for that cartridge, and I have 6 firings on some of the brass. |

The method I referred to saves some of that I have found here. Speaking of the k-hornet, you should go here www.saubier.com/. These guys are into small caliber rifles and may be able to point you to the "right" reamer. Steve |
