Reloading 6.5 carcano

The problem with the big Hornady bullet is too much bore friction and nowhere for the thick jacket to displace to with
gain twist . If you cut .006 deep grooves every .050 down the body of the bullet that contacts the bore you have cut the friction in half and have room for displacement of jacket . You will still seal up and stay straight in the bore without all the drag . Like the original idea as stated in the other guy's post about bore riding bullets , but it works better as the bullet has several points of contact , not just the base . When Barnes was having pressure and fouling problems with their solid copper bullets I told them about driving bands and they now make their bullets with them .
