Home Forums Reloading Bullet Casting Gew 88 .3185 bore, .321 cast load data wanted

I found some gas checked 190 grain RN .321 bullets. I' want to try them in my Gew 88. Anyone have any lead bullet load data or a good load for this combo?
I'm also interested in hearing if anyone used C.E. Harris data and used Unique or Red Dot.
I have IMR 4895, 3031, 4064, 4350,4831, and varget

Are you referring to Harris's 'universal' load of 13 grains of Red Dot?

I haven't used it with cast bullets,(yet) but have in a .30-06 under jacketed 150 gr FP softpoints of the kind intended for .30 WCF. It is a very mild load with a low report, but I don't know how it would work with oversize cast bullets.

Yes, I was talking about the Universal Red Dot load. I can't find a pound of Red Dot to use here in Alaska. However, this weekend, I used the other Universal load of Unique powder. I used 12 grains with no stuffing on top of the powder and a .321 190 grain lead round nose bullet in my Gew 88 (8x57). I only got 1441 fps (average) so I think I bump up another grain. I'm looking for 1700fps. There was no sooting like the mild loads with IMR 3031 and 4895. It was very accurate with 4 bullet holes of five touching.

try 30gr of IMR3031, should work fine. does for me.

Check your groove diameter. I bet a dollar it is .3205 to .321.
