This is a good read, but realize the portion on coated bullets was written a year and a half ago, although there was great information on coated bullets in the article. The three major concerns with the bullets are correct.
1. The number one requirement from the manufacturer is that the coating must be applied properly to get good results, I ordered coated bullets from a dozen or so casters when I started wanting to shoot coated bullets, and all were different quality, some good some bad.
2. Care must be taken in the reloading process to load any bullets including the lead, plated or coated bullets. Seating and crimping in two different operations is good advice, like Dillon does with the 550 and the 650.
3. Accuracy...The owner of Cimarron is an avid IDPA and USPSA shooter, when I introduced him to the cowboy bullet offerings,he graciously bought the molds to start loading cowboy bullets right away, they are now his biggest seller, he took the 105 38 Poly Coated Hy-Tek bullet he coated and shot them out of a Ransom Rest at 50 yds, with a 5 inch revolver and they shot a 1 1/2 inch group at 50 yds, he was amazed, said it was the best group that gun had ever shot, he was use to more like a 4 inch group using a plated bullet at the same distance. So done properly, the Hy-Tek coated bullets I would say are pretty accurate.
Not to sound like Cimarron is the only good bullet caster, there are many, he is very good at what he does, and very knowledgeable on the product he sells, and priced very competitively, I would suggest to anyone to try the coated bullets with an open mind, you will not be disappointed.
