here's a question !! I'm loading barnes 275 gr tsx copper bullets for the ruger BUSHMASTER BOLT GUN.
So far in the prep work , starling cases ,all trimmed to 1.691. +/- .001, cci 400 sr primers and 4227 powder @35 grains . The coal @2.228 +/_ .005.
I'VE BEEN GETTING A VELOCITY BETWEEN 1400 AND 1600 FPS and the best grouping at 100 yds for 1.8" X.8 ".
Has anyone got or found load data or results using this bullet with H335 OR H322 ?
If one seats the bullet at the 2nd cannula (closest to the ogive) these bullets seem to be long at 2.330 COAL . also it appears that anything over 45 grains of H335 would be getting into a compressed load area.
The hogddon 2023 basic reloading Manuel lists the loading for a 300 gr SFT af/hp at 52.0 grs of h335 with a COAL OF 2.065, this appears to be a compressed load with no warning as such.....
So before I go and try anything ,I figured I'd kick the question out there for comment's ..
No I'm not rookie, been reloading for the last 5 decades. But there doesn't seem to be a lot of data out there that I've found to date .! Comments ? please !
