hell;
took a new bersa 380 to shoot with a bunch of reloads at different o.a.l. bullet is a lyman 105 grain cast bullet, sized to .356”.
because of nose design, this bullet cannot have a o.a.l. of .965”, just will work in magazine. started at .960” and went down to .900”. shooting from a rest at 10 yards all groups meassured @3” or a little less. with an o.a.l. of .920” all seven shots formed a single hole. basic question why does o.a.l. make such a difference in accurace?
thanks for any input.
