Sabotloader - thanks for the advice
I received the 50 caliber MPH-24 sabots today as well as the Speer 300 gr. gold dots and 250 gr. Hornady XPTs. I took the breech plug out and loaded both bullets using the new sabots in my "tight" Omega. The sabot/bullet combination was a perfect fit. They slid down the barrel with only a moderate amount of force on the ramrod, and I didn't need the short starter as I previously did with the MPH-12s. Thanks for the great advice and helping me find the proper sabot/bullet combination for this gun. Now I can't wait go get out and see how they shoot.
The great thing about this board is that I have learned in only three months what would have taken me years to find out through trial and error.
Thanks again.
Tom
