Yes, thank you.

+1 on Trail Boss if you can get it for "Powder Puff" loads.

2400 will also give light loads if you can find it.

Try your 4227 powder first for the light loads and save the Blue Dot for last, if things don't work out for you.

If and when you try the 500 or 700 grain bullets, you might need
a good pair of gloves if going to the limit!!

Have fun.
