I’ve been developing a load for my .30 Carbine Blackhawk using 155 gr bullets. Charges between 9-10 gr of H110 produce a very comfortable round and consistent load.
I was inspired by Paco’s Long Range Load For the .30 Carbine Blackhawk.
I’m looking for a heavy, slow(er) load better suited to a handgun.
I took my 155 gr Linotype loads to my range and got this at 20 yards (see attached).
No sign of keyholes which is always good.
