.22-250 Remington Improved

.22-250 Remington Improved
Warning! Notes: CCI-250 primers except as noted. Many loads were vibrated into the case. Maximum loads in each powder/bullet combination were fired five times in the same case to assure the load was safe! These loads must not be used in the standard .22-250 cartridge. All loads should be reduced by at least 10 percent, and worked up, watching carefully for pressure signs. (Handloader Issue 122)
Be Alert: Publisher cannot be responsible for errors in published load data.
