hi guys, i just got a s&w sigma 9. loaded 100 rounds of m.b. 115 gr lrn with 4.2 grains of titegroup. all rounds functioned as expected. last 1/2" of barrel leaded real bad. it took about 40 mins of hard work to remove. i use titegroup and lead rounds in my 380- 357- 45, with no leading to speak of. could this be a bit close to the max i can push these bullets. hodgdon's web site gave 3.9 to 4.3 as the charge. i am using lee's auto disc .37 hole, if i go down to the .34 it is right around 3.8-3.9. would this be too low of a charge???? at 4.2 gr my brass is 6-8 feet away, would a lower charge not throw it as far?? any ideas are a great help
