The story behind the "top strap" gas cutting and the "gun writers"
that gave the Max it's bad rep is a story in itself. The ONLY you will know what YOUR bbl is capable of is to load up several test loads ,scope it and test it, be sure to take the 7-30 also as you know what it/you are capable of , a simple way to see if it's the Max/load or you.
Got any friends that cast 180-200 357's get some and test them as well.
send me a PM and I'll send you some loading data for the Max that was in Handloader Mag. of March/April of 1986
