Home Forums Hunting & Shooting Combination Guns and Drillings Need Bullets for your 8mm J-Bore ?????

I wanted some jacketed bullets for my two J-Bores. Slugged the barrels and they measured .320 and .321. For some reason, even the one that slugged .321, did not like the .321 jacketed bullets. Had Lee cut me a .319 dia. bullet sizer. Using their case lube, I run Speer Hot-Cor .321 170gr bullets easily through this sizing die. Both rifles are shooting very tight groups with these bullets, they both turned in 1 hole groups at 40yds. I am going to run some 200gr. jacketed through it before long and see how they do. Have had no basal damage to the 170 grainers. I am very very happy with this little experiment.

Now, I am not relegated to only cast bullets, or very expensive jacketed. Hope this is of some use to fellow 8mm J-Bore shooters.
