i have a win. model 70 in 300win mag it has a boss on the end of the barrel.i`ve worked up loads in my 308 down to almost one hole groups at 100yrds (lots of combinations) would like to load up some 180`s for the 300, but was wondering when to bring the boss into play. will probably use this on elk or maybe just shake and bake some whitetails with it, any ideas will be helpfull thanks patience pays

Songdog, apparently none of the handloaders here have a rifle with a boss on it. I have loaded some ammo for a friend who has one and what we did was pick the bullet he wanted to use, and then loaded up one grain at a time to close to max loads with three powders and picked the best shooting one. Then we loaded up 20 rounds of that one and went back and messed with the boss. Good luck.

songdog, I have a 30-06 Browning with the Boss. In finding loads for it, I check several sources for data. I tend to look for loads that are relative fast, use enough powder to fill the case. I try to find loads that are consistant in speed. Then start loading up plenty of ammo. Then at the range I start with the suggested Boss sitting, shoot 5 shots off the bench and adjust the Boss about 1/4 turn. Then repeat until i find the best setting.

Good Luck & Good Hunting
