Thank you Mark.

I scored two pounds of Reloder 16 at Bass Pro in Houston today so as soon as the monsoon season abates I will be able to get out and give this combo a try. I have 55 gr Nosler BTs, Norma once fired neck sized brass, and Federal primers ready to go. What intervals of powder charges would y'all use for a ladder test.

For a small case like the 220 Swift, I would use .3 grain increments for the ladder test, its my preference. After finding a node, I would try again in .2 grain increments to tweak 3 round charges. Good luck Bruce.
