"I have bought thousands of bullets from Dardas. 9 mm, 45 acp, .40 and 380 acp. He as the best prices as of the time of this review and also has excellent quality and shipping. He offers slugs to slug a barrel to find out the size of your bore. After slugging your barrel you send Dardas the slug, he measures and you buy a bullet that is .001" over the slug size. This is a free service. The leading in my barrels are very minimal to nothing, depending on my barrel. This would be a barrel issue, not a bullet issue. If you are into reloading you should give Dardas a try."
