I haven't shot my 6.5 Sherman in a while and figured it was time to dust it off. Basically, think of it as a 6.5-280 AI. Different ways to form, but I used Peterson 270 Win brass.
- Necked up 50 cases to .284, then necked down to establish a false shoulder (too much shoulder movement to just put in chamber and fire).
- Trimmed to 2.525", then quick chamf/deburr
- Loaded up a few rounds with 53 grains of RL-23 to fire form the cases.
Swung by the range and popped them off. Shoulders appear to have formed nicely at this charge, so I'll get the remaining 45 cases loaded today. Once these are formed, I'll work with the 156 Berger and RL-26.
False shoulder on L, fire-formed case on R
