Did you Chrono these? Using the same powder, 36 grain weight with a 150 Nosler Ballistic tip I'm getting an average of 2300 fps from my Handi Rifle. Accuracy not quite as good as yours, but good enough for deer in the 200-225 yard range. I Was going to do more work with load development and perhaps try fine tuning the rifle a bit more but decided that good enough is good enough. I may yet try upping the powder charge to see what speed vs accuracy I can get
