I ordered a Seneca /Sumatra carbine from p.a. today, I will see what It slugs at.
Years ago, that 25 acp bullet was the first slug I tried in a Condor, the chocked barrel made it a non starter. I purchased a
.254 lbt mold and a Lee w.254 sizing die, and a new hacksaw blade, used the 253 sized slug inside and the hacksaw on the outside. I then learned You can change the choke but not the twist.
Next was to try a 257 TJ and 257420 mold I had laying around in the last 257 Haley Scandalous Jack made, that was when I started making video’s exploding 12 oz cola cans at 500-550-615 yards, that was in 2014.
I posted almost most daily groups from 260 to 300 yards on the old Yellow under Unrepentantsinner with that Haley.
