Inthebushes Posted March 21, 2018 Report Share Posted March 21, 2018 Is velocity the same? Quote Link to comment Share on other sites More sharing options...
98Z5V Posted March 21, 2018 Report Share Posted March 21, 2018 Usually not. Depends on powders. Impact range, too. 100 yards isn't much, if it was that range. List more details in the post, besides what's in the title. Quote Link to comment Share on other sites More sharing options...
Inthebushes Posted March 21, 2018 Author Report Share Posted March 21, 2018 250 yards. First powder was H335, second powder Varget, third powder H380. I know the speed for H355, it’s the load I use all the time. The Varget and H380 loads, I just manipulated until I got the same POI. I didn’t have a way to check the velocity today and it just seemed plausible velocity would be similar if not the same. Thought I would ask, because I’m usually wrong. Everything else was the same; brass, primer, OGIVE, crimp, weather, etc. the only variable was the powder. Quote Link to comment Share on other sites More sharing options...
mrmackc Posted March 21, 2018 Report Share Posted March 21, 2018 You are close,very close. One more check you can do with same gun same case,same bullet, same target,same zero, same distance, same P.O.I, different powder. ...using the same sight setting check POI at half distance of original with the different powders this will provide proof arc is same and that M. V. Is same. Quote Link to comment Share on other sites More sharing options...

So, the charge isn't the same weight. That's doable. Different charge weights for different powders is a different story. They probably all are the same velocity, or close. List the charge weights for all 3, if you don't mind. Quote Link to comment Share on other sites More sharing options...
Inthebushes Posted March 21, 2018 Author Report Share Posted March 21, 2018 H335/29.5. Varget/29.5. H380/32.0 I thought there might be a “law of physics” covering this, but I didn’t do well in physics, in fact I think I missed physics all together, and I’m not sure I’m spelling it correctly.

98Z5V Posted March 21, 2018 Report Share Posted March 21, 2018 I know my Varget loads and my RL-15 loads are damn near identical, with the same performance. Never heard of H335 being the same, but I've never used it for anything other than light-projectile 5.56 loads. What are you shooting that's running 29.5 and 32.0 grains? It ain't .308 Win. Let's get to the business, and get all the info out here already. Quote Link to comment Share on other sites More sharing options...
Inthebushes Posted March 21, 2018 Author Report Share Posted March 21, 2018 Caliber was 6.5 Grendel with 100 grain ELD. Some guys had told me they were getting good velocities with Hodgdon LeveRevolution in 6.5 Grendels. I didn’t have any LeveRevolution, but I had H380, which is next to it on the burn rate charts. I started really low and just came up to my POI established with the H355. The Varget load I just threw in there because I had some sitting there, and I had nothing else to do. I believed the H380 would be too slow, but maybe not. The H355 load is pretty hot and shoots well. The H380 load was shooting well and showing no warning signs. It may have a little more room yet. I know the Saftey Monitors will surely be after me. Quote Link to comment Share on other sites More sharing options...
Inthebushes Posted March 21, 2018 Author Report Share Posted March 21, 2018 Not really a .308 question, more theory question for the reloading gurus. Quote Link to comment Share on other sites More sharing options...

Well, the only 100gr 6.5 ELD from Hornady is the ELD-M, with BCs of .385 (G1) and .194 (G7). Depending on what you're doing with it, you'll be far, far better off loading up something heavier, like the 123 ELD-M, with BCs of .506 (G1) and .255 (G7). Target bullet for target bullet, the 123 will be far better off at shorter distances and longer distances. 4 minutes ago, Inthebushes said: Not really a .308 question, more theory question for the reloading gurus. That pertinent piece of information would have been helpful up front, instead of getting it through questions. I'm loading Accurate 2520 for Grendel, 123 ELD-M over 28.5 grains, CCI 400 primers. It's giving me excellent results so far, through two guns with different barrel lengths. Here's the details, with more distance confirmation coming up. This was what I observed this last weekend...

Inthebushes Posted March 21, 2018 Author Report Share Posted March 21, 2018 Your right. Great reports, how are they generated? The Grendel is for Junior, he is 9. He has been using AR 243 with 20 inch heavy barrel. He does really well with it, but it is heavy for his size. Hell, it’s heavy for my size. He took 2 deer last year with it, both at 300 yards, both called neck shots. My goal is specific, flat, light gun, light recoil, 250 yd to 300 yd target and hunting. The target we shoot is 250 yds. The food plot we hunt is 325 yds to where the deer normally come into the plot. The 100 ELDs work well at the 250 yd target, the gun is zeroed at 250. Will definitely move to a 120 something bullet for the deer. Any suggestions on the heavier hunting round? Would appreciate the above reports with a 250 yd zero?

Any suggestions on the heavier hunting round? From what I've been reading the .264 Nosler AccuBond Long Range (ABLR) in 129gr is a fantastic hunting round. It expands down to 1300 fps., has excellent accuracy, and offers great weight retention. I haven't tried any of them yet, but I will be loading some up n the future and working up a load. I have some Barnes 120gr TSX projectiles to load up. Those are always proven performers. Quote Link to comment Share on other sites More sharing options...
Inthebushes Posted March 21, 2018 Author Report Share Posted March 21, 2018 SPS has some blemish 129 accubonds $33/100. I think I’m going to order some of those. I have had some issues with blemished target bullets from them in the past but I’ve also had some that worked great. For a hunting bullet, I’m guessing they will be fine. Thanks for the info and help. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted March 22, 2018 Report Share Posted March 22, 2018 (edited) Make sure it's the AB Long Range, the ABLR. I think the standard ones (non-LR) have a different expansion threshold. It might not matter, though - you'll have a long distance shot to make to get the velocity that low, or shooting from a short barrel in order to... My 12.5" is above 1300 fps at 600 750 yards, in that chart above... Edited March 22, 2018 by 98Z5V Quote Link to comment Share on other sites More sharing options...

Same experience here. Some of the SPS blems were very good, but most gave less than desired results. Same with the "blems" from Midway (I think those were Hornadys). I've since stopped buying anyone's blems, and only get Sierra projectiles, or Hornady 75 BTHP for the 5.56. The blems are good for hitting steel, and short range stuff. Only problem, I stocked up on the SPS blems during the Obuttf*&k years. Still got a lot to go thru. Quote Link to comment Share on other sites More sharing options...
