Ed, I shot some LT32 in my Howa 204 today. I was cautious so I started with 25 and 25.3 grains with BK32's. It was too light a load as the speed was 3815 and 3842 fps, respectively. I was shooting at 200 yds and had about 1.25" of vertical with no horizontal to speak of. I will up the loads and...

those groups show some promise, but I always try R10 in every 204 ruger I have owned. It has proven to be very accurate in most. Between
24 and 25.5 grains with the 39 grain Blitzking, start low because some lots are faster the others. use your chronograph to get upto 3750 to
3800 fps. Rogina

The NN140 I have, which is about 20 years old, is about the same speed as the 4350 group of powders. It may be too slow for the 204 unless
you are going to shoot awful heavy bullets. Be careful. Rogina
