um, why not just buy the ammo the way you want it... 22 ammo is cheap...
Very interesting read about the Paco Kelly’s AT System Flatface Rimfire Bullet Reforming Tool:http://gunblast.com/Paco-Flatface.htm
ConclusionsWell, the most obvious question, is why bother? There are dozens of commercially available hollow point rounds out there for the .22 shooter - from flat nose rounds like CCI's SGB, to shallow hollow points like Winchester's Rabbit Ammo, to regular hollow point designs and the more explosive ones like CCI's Quick Shock, Power Point or the Stinger. It's hard to see a niche that needs filling in .22 hunting ammo - and in my experience expansion of .22 ammo on the likes of rabbits is unreliable. it's not often I've recovered an expanded .22 bullet from a bunny, and it's been the obvious ones that have shown up - Power Points, Winchester Expediters and occasionally a Bushman. In any case, if you are head shooting expansion is irrelevant. My other concern is for the inconsistency that will occur while forming the bullets shapes - both from different amounts of force applied, and also due to the slightly skewed angle the punches can impact on the bullet noses. Certainly, the more radical designs were totally unreliable and very inaccurate.As for the terminal performance aspect, if your rifle is struggling with a brand of ammo, try one of the many others around, until you find one that shoots accurately. I'd certainly be trying different ammo before I bought a tool to try and "accurize" ammo.In short, while it was an interesting experiment, I wouldn't buy one of these, and I think the claims of possible better accuracy and dramatic bullet performance on small game are somewhat overblown.
