Diamond Curly SASS#57086 Posted September 20, 2019 Share Posted September 20, 2019 I have a H&R rifle in 38/55 that I have a load of 30 grains, by volume, under a 245 grain bullet. This load does decent up to 200 yards but is very flat after that.. I tried a few shots at 400 yards and the spotter said it was very flat and very short. Any help would be appreciated. I shot my trap door in 45/70 with a 535 bullet for a few years with good results but my shoulder said no more. The 38/55 is fun to shoot but maybe I am expecting too much out of this caliber.

Michigan Slim Posted September 20, 2019 Share Posted September 20, 2019 They aren't barnburners even loaded hot. But, my daughters rifle puts them on a 300 yard target pretty easy. Aim higher! lol. Her load is 10.0 grains of Unique with a 250 grain Lee bullet. If that thing gets there yours will too. Tall quality sights required. Link to comment Share on other sites More sharing options...

Thanks, DC 30 grains by volume is not a full case for a 38-55. Should be around 45-50 grains. Did you make a typo or are you using a filler? Are you using 2F or 3F?

The bullets are from Whyte big lube and I just weighed three of them for an average of 245 grains. One did weigh in at 251.Thanks, DC Link to comment Share on other sites More sharing options...

Hoss Posted September 21, 2019 Share Posted September 21, 2019 10.0 Unique in my HiWall with 260 grn bullet works well. Wind will have a pretty big effect on the bullet. I’ve shot mine out to 500 meters, but if it’s windy, it’s tough. Good sights are a must. If you are shooting a H&R Buffalo Classic you can’t mount a tang sight as no steel tang. While you could mount them on wood, they won’t be as stable. The 38-55 is a good target load, but has it’s limitations, primarily due to wind. The heavier the bullet the better, mine can handle a 310. I tried 335 but the would not stabilize. Sounded like a bee going downrange! Link to comment Share on other sites More sharing options...

DC To put that in perspective, I aim 30 inches or so high at 400 with my 270. Your lobbing them in. Aim HIGH. Link to comment Share on other sites More sharing options...
Sedalia Dave Posted September 21, 2019 Share Posted September 21, 2019 Here is the 38-55 ballistics data for a 255 grain soft point. As you can see at 400 yards the drop is 161 inches and change. I ran the numbers for a .375 Winchester shooting a 200 grain Winchester Power-Point at 2199 fps and it drops 78 inches and change at 400 yards.
