      Yeah, I'm really liking this........... and copper-solid is a nice way to start....... guess deep down I yearn for a bonded core.......
      But I'm still a fan - learning a lot too.
      BFT great idea to get this ball rolling.

In the Grendel Handbook vol 2 (p. 49) it seems to suggest otherwise for the 100 gr ttsx, ie, at higher velocities there is more expansion, up to 2x more than the lowest in the table and rather linear with velocity. Plus, I'm thinking that Barnes et al may have some good reasons for the tip sizes they chose...
        Just my thoughts of course...
        For economy sake what MakerB says, makes some sense...
        I think this is more of a minimum expansion threshold issue than anything. Thats why we are asking for a bullet designed for the Grendel velocities with low end expansion in mind. The 100 TTSX is designed to be pushed much faster as far as i can tell, or used at shorter ranges. If they are going to maximize the potential range of a bullet they might as well design it to expand way out there.

          Good point. Did we say back there anything about a min opening velocity? If not, then how about ~1500-1600 so we take advantage of the Grrr. Probably too much to ask for 1300 like the ABLR...

            This

            The 100 TTSX is listed a 2000 min opening at about 350yd in the LFP thread.

              That is part of what I was thinking about when posted earlier in this thread for say a 110gr LRAB

                Good. 1600 works. 2000, even 1800, is too high IMO.

                  That's why the 6.5 mm molds you see are in the 140 plus grain weights.

                  Sorry I have no idea of what you are saying. You suggest I design something around 3/4" long, flat base and 4 ogive?
                  And why are the molds all in the 140g+ range?

                    Lead is so dense that in a cast bullet you can only get a 100 gr bullet to those specs if you make any larger than 3/4 inch it will be heavier. Thats why you need an alloy or copper to reduce total density. Think about a 22LR bullet at 40 gr how big would two and a half of those be melted together? Not a full size 6.5 bullet.

                      Thanks for the info. I've been looking at the 140g molds and wondering why those designs couldn't be shortened?
                      There is a 125g mold available but I'd prefer lighter than that.
                      I'm wanting plinking bullets but would like them to be relatively accurate out to 300-500 yards? Possible?
                      Hard cast with a small amount of tin and antimony. Powder coated for velocities up to 2500fps.

                      Custom molds are expensive and I will have to learn a lot about bullet design before I spent the money.
                      I love the idea though, when even the cheapest (on sale) jacketed factory .264 bullets are 20-25 cents each.
                      I'm not set up yet but will cast 9mm and .224 bullets first.

                        N.O.E. has 125gr and up for the 6.5s and they have one much smaller 54gr at http://noebulletmolds.com/NV/index.p...4oil35l20ljji4

                        Not sure if link will work, I though Ranch Dog had one smaller but could be wrong, he likes heavy bullets with a large meplat as they work so well on game. Ranch Dog retired a few years ago but some of his designs are available at N.O.E. and Lee

                          Thanks, yes I was aware of the NOE molds and I will very likely buy their 5-cavity 126g.
                          I wonder if that 126g could be shortened by taking out a section from the middle (area within the .250"). Then possibly a little off the back end to decrease the bearing surface.

                          Any cast bullet design more than a couple of years old has lube grooves that aren't necessary for coated bullets, another area for experimentation.

                          Edit: Actually, I'd like to see a copy of a 100g HPBT jacketed bullet (with a flatter, shorter nose to facilitate casting).

                            LR1955: DU makes an armor piercing bullet according to the law. Natural or enriched are OK, but some people use enriched or other things.

                              Lee offers a custom mold service where you supply the design, they do the design and make the molds on approval from what I have read, not cheap but an option. https://leeprecision.com/custom-serv...-bullet-molds/
