I have been using my Lee 175TC six cavity for about a year or so I guess. I've cast several thousand bullets with it and they shoot great. They weigh 180 grains with the range scrap I use. But, I have tons of 165 grain Ranger T's and SXT's. I also don't have any real need for the extra 15 grains my cast bullets carry around and wanted to put them on a diet. I thought about hunting down a machine shop or sending the mold out to the Eric hollow point guy. A combination of laziness and stinginess has resulted in me using the mold as Lee intended it. What I didn't know was that becoming a soccer dad had certain benefits. One of my fellow soccer dads is a machinist. He works in a shop that builds high end racing engines. I asked him about it and he told me it would be a piece of cake. So, using a little geometry, I guesstimated that 0.050" would have to go. He got it back to me the next day, today, and it looks great. Hopefully this week I'll get a chance to fire up the foundry and see how much they weigh, and then how they shoot. I don't care if they are a little over or under, I just wanted something a bit lighter. The Ranger 165's do 1050 out of my G27, and I get close to that with the 180's with Unique. So, I figure I can get basically the same velocity with the lighter bullet and have lower pressure. Lower pressure is always good. The 180's hit a bit higher than the 165's too, so hopefully the point of impact will be the same with the cast 165's and the Ranger 165's. We shall see. I think a max load for 180's will give me the velocity I want and be within the pressure limits with room to spare. Load data for lighter cast bullets is rare, I haven't seen any. Any thoughts or data regarding having this mold decked down are appreciated Wanna kill these ads? We can help!
