What powders are best for .223 Remington?

[Ted_Feasel]

+1, Ted. Here's another group @ 100yards, same recipe, but with Nosler Ballistic Tip. Have used a newer Savage 12 with a 9 twist barrel to shoot a sub 3 inch 5 shot group at 600 yards @ the CMP Talladega Marksmanship Complex range using 60 grainers. https://imgur.com/68AMjV0Heck yeah:) nice looking group.

The bottom hole is a 33 shot group at 200 yards, the top 2 are just shots I was playing with the bdc marks on that scope to see how accurate they were. AR15 6.5 grendel 123gr eld 29.5gr w748.https://uploads.tapatalk-cdn.com/20190410/0ec3e89f4907d9edf2d472d5be0e4f74.jpg

Really consistent shooting, Ted! I am extremely happy with W748 powder, too. I have lately tried some of the Hornady Superformance hybrid powder .223 factory ammunition (53 grain polymer tipped bullets) that I received as a gift and they showed great promise, accuracy wise, for factory loaded rounds. They give around 175-200 fps more velocity than standard loads, with no increase in pressures. While there are some types of Superformance branded powders available for bigger cased cartridges, unfortunately, Hornady does not offer their proprietary blend/burn rate for the .223 class capacity to handloaders at this time.

Ted, you've got that right....after developing just the right handloading component combination, powder charge/bullet weight, and seating depth/C.O.A.L., it is hard to mess with success. A large part of the satisfaction in shooting for me (especially longer ranges) is devoting the time to developing the most consistently accurate load I possibly can for a particular rifle. I started making real progress when I bought a good chronograph and could measure not only individual shot velocity, but E.S. and S.D. I soon learned that I could sacrifice 5-10% velocity to gain up to 20% better repeatable, consistent accuracy. Optimizing the whole system; ammunition, rifle, optic, and shooting technique is how to reach the full potential available.

I have been using IMR 4198 for 52 gr SMK for decades.

If I were working up a new load I'd look close at Benchmark powder.

[Ted_Feasel]

I usually look at burn rates and factor in barrel length while trying to find a powder that comes closest to filling case to capacity or even lightly compressed.. this has got me great results virtually every time. Maybe it's my imagination but it sure seems the less powder slope in the case, the better and cleaner burn I get.

I have also had good results with BM2 and Sierra 53gr projectiles
