.454 Casull loading question
I bought a RSRH Alaskan in the .454 casull a few weeks ago and now its time to start loading for it. I bought some of the hornady 250 grain xtp bullets to try first loading them in the 454 brass. I have the hornady 8th edition reloading manual. would it be better to use the standard 45 colt load data or should i use the (ruger only) 45 colt data. Using the standard data would all the empty space in the brass be bad or dangerous. I would most likely be using herco the manual states 8 grs. Or would using the (ruger only) with 20 grs of 2400 hundred be better.
