If this has been discussed at an earlier time i apologize for i did look through the forums with no luck on the subject. I sat down here a little while ago to work up a new hunting load for my G20 10mm. All work is going to be done with Longshot powder, 180gr XTPs, new brass, and WLP. The Hornady 8th edition list an OAL of 1.26 and starts with 6.4gr of powder with a max of 8.2 gr of powder..... Now Hodgdon lists with the same OAL of 1.26 a starting load of 8.5gr of powder with 9.5gr max load.... Im confused here... Seeing how Hodgdon's starting load is over the Hornady's max load.... Why such a difference between two of the largest known companies in the business?
