I just got done shooting my second batch of reloads. I' shooting commercial cast 158gr lead SWCs over Titegroup in .38 and .357. I'm getting leading in the rear of the barrel in front of the forcing cone. I read this thread:
Leading problem with Taurus Tracker .38/357 loads.
http://www.thehighroad.org/showthread.php?t=724521
And I also read the Fryxell chapter on the topic. I also get lead in the cylinder throats. The bullets are sized to .356 to .357. From what I can read my barrel slugs out to be .355. The bullets are tight in the cylinder throats.
My questions are:
Should do like Fryxell says and fire lap the revolver? or
Should I just get the throats reamed? (if so... what size?)
Would cutting them at .358 allow too much gas bypass in the throat?
I think I get more Lead in it with the lower pressure .38 cases. Should I just move up to +P to get the pressure up on the bullets in the .38? I would like to work with what I have for now. I have about 400 .38 cases and only 25 .357 cases.
I do have a strong interest in casting my own and have been researching a lot lately. The revolver will see some jacked rounds but not many. The leading is not too hard to get out of the barrel but it is difficult to remove from the cylinder throats. I mainly just don't want to scrub so much.
On another note. I did the best shooting Ive ever done today while testing. a nine shot group of 2" and a five shot of 1.4" both rested and at 7 yards. No Bullseye shooter but I'm happy. Maybe one day Ill get it out to 50yd.
