      Why not have a good Loverin style for the various .338s? The 338 Fed, 338 ME, and 338/06 all have a solid fan base, and the 338 Win is an indisputable favorite. You can add Weatherby, Ruger, and Remington to the list of offerings available today.
      I’d like to see an offering in the lower 200+ grain range for the short-necked 308 class options, and a 250+ for those long necked 338/06 types.
      I’d be in for both.

        Yup I’m in.  A Loverin hunting bullet (is it boolit here?) in the 210-225 range for short neck cases.  HP and FN pins…

          What is the minimum meplate you can live with?

            I’m open to any option that gets this going, Frank. I can always change alloys, or even use a Forster to hollow point for hunting applications, if necessary.

              Ok, I’ll draw up a mold for the 338 Fed (210 gr) and another for the 338/06 (250 gr).

                Sounds good, Frank. I look forward to seeing your end result.
                I wonder sometimes what the practical limits are for orbiting cutting bits with the CNC machinery. Could an existing 30 cal, or 8MM set-up be used for .338? Could the .338 be used for .358, 9.3MM, or even.375?
                Maybe AL will join in with a little insight.

                  Interpolation, circular pocket milling, works great.
                  We have taken .359 form tools out to .513 with no problems.
                  There’s not much limitation.

                    Here are a couple of molds to ponder over. The 1.135 long one will work on both 338 Federal and 338/06 but, will be short for the 338/06 A-Square freebore..

                    The 1.29 long one will work only on the 338/06. To my knowlege, there are at least two 338/06. One with a standard 1′ 22″ tapered throat and the 338/06 A-Square with a .220 long freebore. This bullet is the best compromise I could do. It’s designed for a COAL of 3.34. The A-square has a .100 longer COAL at 3.44, that would be to long for many ’06 mags.

                    The 1.135 long mold, will not fit the 338 Marlin Express. The longest mold that you can use for that one is 1.05 long.

                      Those look great, Frank. Thanks for your time and effort.
                      I believe I need both these… Now to find enough .338 fans to make it worth Al’s time.

                      Al, would you have tooling from previous Loverins that you think would be good candiates for this project?
                      Thanks for your time, my friend.

                          I like the short one too.  But I have an obviously noobie question. 

                          How is the shank diameter determined for a gas check?  All I can do is read until fall chores are over and the weather cools down to try casting.  So I have nothing to offer in wisdom thoughts or ideas for, well, years!

                          http://noebulletmolds.com/NV/product_info.php?cPath=33&products_id=640&osCsid=cgcs3ar1dl5730thtcbgc06pj2

                          http://www.lasc.us/Brennan_4-2_GasChecks.htm

                          http://castboolits.gunloads.com/showthread.php?11997-Gas-Checks-vs-Shank-Size

                          http://www.lasc.us/CheckShankSize.htm

                          These charts indicate gas checks need a max shank diameter at 0.327″ for a Gator.  The Hornady chart indicates ID of the GC is 0.330″ so maybe the 0.327″ for a Hornady too?  The 340320 201Gr. in the first link has a diameter of 0.329″…

                          So will the above drawings work just fine for gas checks?  Would they be too lose?  Not being critical, just curious.  I have no way of knowing…

                          Thanks!

                            eeyore,
                            Thank you very much for bring that to my attention. The CAD program selects the GC dimensions and for some reason, the dimension for the 338 is WRONG. I will go back and correct the drawings.

                            It’s not that there was a glitch and it picked the wrong one but, it’s wrong in the data base that stores the GC data.

                            Al, if you read this, could you please give me what you use as standard 338 GC dimensions?

                            Frank

                              I just looked at the “Frankenstien” and the 340320 molds and the both have different GC dimensions. It looks like the “Frankenstien” dimensions would work for the Gator at .326 x .329.

                                Part of our procedure is to control the shank size at the time we run the cavities
                                We cut the first mould cast with it and measure the bullets from it.
                                At that time we physically try GC’s on and make any adjustments to make them fit.

                                We have found discrepancies with the information we have seen from all the manufactures
                                And we have seen variances of .0010″ to .0025″ from batch to batch of GCs from just about all of the manufactures.

                                This is a list that we work from.
                                Taken from samples we keep on hand.
                                Gator 22Cal .214 Hornady .214

                                Gator 257Cal .243 Hornady .243
                                Gator 264Cal .252 Hornady .253

                                Gator 358Cal .343 Hornady .342
                                Gator 375Cal .354 Hornady .255
                                Gator 41Cal .381

                                Gator 458Cal .428

                                TMT’s drawing software generates a list also.
                                We do our best to make it all work.

                                I hope this helps
