Recent trip to the Range
Saw your post. I have been lurking for several months - always polling for new info! I have been loading 45LC for several years (Linebaugh loads!) - but that is a different story for a different thread. I will soon load some hot 240g JSP's - just to clean out any lead deposits (just haven't had time). Hope this info doesn't start a range war. I have seen to may of those on other boards.
Here is the summary I recorded from my first trip to the range with my new Trapper - hope it helps:
