I test loaded two cartridges before I left the house this morning with bullets resized to 0.427 and they both came off correct without loose bullet tension. I did note that as described in earlier posts the expanding button if allowed to oversize the case mouth does have an impact.

I intend to shoot it with the jacketed 0.427 bullets to see how they do before I move up to anything larger.

I need to cancel my order for 0.423 258 bullets from Hawks as they will not be of much use.

Once I have nailed down the best regulating load with the Hornaday XTP 240 grain, I may go ahead and see how it does with the Hornaday FTX 265 Grain at 1800 FPS

It will be two weeks before I will be able to get to a range again to fire my next lot of reloads
