Re: Two uncommon Mannlichers

Hi LD--

It's still a work in progress--the component shortage last year put a serious crimp in my ability to experiment, and frankly the rifle's original optic doesn't help which is why I'm trying to get a modern scope fitted up. What I have determined is that the 37-39 gr. Norma 204 load with the 160 Hornady RN is a good bit hotter than the only published recipe I was able to try out of the Hornady manual, using H4895. The maximum velocity for this powder/bullet combo is 2000 fps, which seems pretty marginal in relation to bullet performance. On the other hand, I used the H4895 behind a 140 gr. Hornady SP (around 2100 fps) to kill the prongbuck, and it worked great. I've got two lbs. of Norma 204, and with moderate resizing I can get 8-10 firings out of Norma brass with the above-mentioned RN load, so for now I'm staying with that.

Malcolm
