A few months ago I asked about sabots using short cast bullets in my 50 cal flinter with a 56 twist . The sabots were the crush rib type a member here sent me to try, bullet were the Lee 200 gr flat nose in 45 cal . These are shorter than the 200 gr Lee reals I tried before in a 45 cal with the same 56 twist so I had some hope . I loaded these with my normal round ball 70 gr of 3F load
The good were they cut nice round holes at 50 yd so they were stable and not keyholing . The bad is accuracy was poor I fired 3 rds with a group in the 1 foot range . The Lee reals never shot great for me but always better than that !
