    Elite Ammunition 98 grain solids. Load data and BC?



    Well thanks to LRRPF2 I had to order a couple boxes of these. Thanks buddy! Now I'm looking for some good loads and possibly some ballpark BCs. I have a 24" barrel. Any help would be greatly appreciated. I know loading solids is not like loading traditional lead core bullets. I haven't got the foggiest idea on what the BC would be.

    I emailed Elite Ammunition as well so I'll share the email with you guys if they answer.

    Cheers

    The reply to my email:

    Our insurance does not cover us publishing load data.

    I can tell you the bullet is light for size. Start with the load data for the 120gr TSX bullet.

    Due to it extreme tail stabilizing the the air behind the bullet, and light weight for size, the BC is around 480

      If the BC is close to .480 (I'm doubtful, but hopeful!), and you can push this sucker hard, I could approach 2925 FPS from a 28" barrel.

      That's significantly less drop and drift than the 123 Sierra at 2700 FPS.

      However, solid bullets have a habit of causing higher pressures than lead core bullets, (less "squish" in the bore, I think) even with less engagement surface in the lands. That probably screws with the possible velocities.

        Put that chart in mils man! I'm horrible at those conversions. LOL just kidding man. Thanks for the info.

        Stanc,

        I'm pretty sure they're very optimistic about their BC. I'm going to have to try these 100 yards (or even 50) at a time past 500 i guess. I was just talking to LRRPF2 and they sent him the 6.8 SPC bullets by mistke. He weighed them and saw big differences in the weight ranging from 76.1 to 77.6 grains.

        I'll do a video on them when they come in. I'll weigh them, shoot them, and then shoot them at longer ranges if I can get them to group up.

          MSP:

          FWIW, you won't notice a difference between a bullet of .48 and .46 BC's. Also, I wouldn't get too hung up on a 100 grain bullet varying in weight by a grain or two although it isn't something that a bullet maker wants to happen.

          What you want to look at is that the bullets are identical in size with emphasis on the part of the bullet consisting of the majority of the ogive through the tail. You can take some hits in terms of how sharp a tip is but if the bullets vary in where the ogive is, you will have problems at distances from about 300 and farther.

            Good god, that does not fill me with enthusiasm

            My point being that does not look like an ideal amount of QC, not exactly Six Sigma going on there.

              Yeah,

              I weighed a bunch of Lapua 123gr Scenars, just to re-check my sanity, and they only had a spread of .2 grains in weight variance. The 6.8 SPC 77gr solids varied quite a bit. I'm not sure what advantage one would gain with them in that caliber. I was thinking of seeing what type of close-range carnage I could inflict with them in my .270 Winchester, but I'm sending them back. 3100 fps with 130gr is plenty for me in the .270 Winchester.

                You won't find too much spread with lead core bullets. Solids are another matter.

                I am just not sure it will mean anything in practical terms unless the bullets are also off balance.

                  Thanks for the info LR. Insightful as always. I guess I'll do my measurements with a set of dial calipers instead of a scale. I really want these bullets to be good shooters. You helped me regain my confidence in them, and I know if I think a load is going to be crap it's going to be crap regardless of wether it really is or not. Psychological effect and all that.

                    Update:

                    Got these in the other day. I measured for length and weight. Out of 10 samples I saw a 0.004" variation and a weight variation of 0.3 grains. Majority were 1.335" overall length and 98.0 grains on the money.

                    I shot them today with some loads worked up using Accurate 2520. Loads ranged from 28.0 to 31.0 grains. The best load I found was 30.5 grains followed by 30.0 grains. The other loads were absolutely horrible, but seemed to get better as the charge went up until i hit 31 grains where it opened back up again. I had one called low flier with the 30.5 grain load. I'm shooting a 24" Sabre Defence barrel with a 1-9" twist.

                    I'm going to give TAC a try next and see what happens. I may also look into some LeverEvolution loads.

                    The two groups below were both shot today. The first one (in the dot) is the EA 98 gr solids. The second is Hornady factory ammo. That should give you a good idea of both the ability of my rifle and the shooter. Keep in mind the low shot was a called flier, shooter error.

                          Nice shooting. Any velocities?

                          How about at 600+ yards?

                            No, didn't have any time to go borrow my buddy's chrono. I just got the bullets in on Tuesday and started load developement. So far I've shot 5 different charges of 2520. They varied from around 3 inches @ 100 to the group in the pic. They seem pretty finicky on velocity or charge density to me so far. I'll get some TAC rounds worked up and try them by the end of the weekend.

                              155 wants to know if that is a regulation dime in the photos. You might want to try something like H335.
