I've been working up loads for my AR recently. Looking for a less expensive alternative to the Sierra March Kings, so I've been messing around with the Hornady BTHP. See the video below for the info:

The way you get two measurements out of a five shot group is wonky. You either shot the full five shots or you didn't. The pick and choose group size means nothing. Statistically most of your shots are going to be close together but it's the ones that expand the group that are the true measure of you, your rifle and handloading. I'm curious why you're shooting a mid range bullet bullet for accuracy? If you want to test your rifle and shoot small groups, use a bullet meant for small groups, not one meant to fight the wind at 300-600 yards. Get some 53 grain flat base bullets for shooting bugholes at 200 yards or less. |

Any "wobble/sleep" issues are for those trying to shoot Official Screamers, or less than 0.100" at 100yds. ETA: vid embedded  |

Edited. Caution. AeroE
ETA: Black Hills Ammunition uses a "52gr Match HP" and 40/50/60gr VMAXs. OP, I'd keep working with 24gr RL15. I'm betting those single "flyers" are you. From Konrad Powers, a National Service Rifle Champion: http://www.sw-hearing.com/konrad/reloading/reloading_procedure.html All my ammo, including the powder charge, is the same for all yard lines except for the bullet. I use Sierra 77s for 200 & 300 yards. The Sierra 80 is used for 600 yards. For those that are curious, that powder charge is 24gr. of Reloader-15. The primers are Remington 7 1/2. Elsewhere on his site, regarding his "load development": Besides, I just asked the shooters that were winning matches what loads they were using in their rifles and copied that. Seemed easy enough. The 68gr Hornady BTHP is about as long as the 75gr BTHP and 77gr SMK. Having a secant ogive, it's more sensitive to distance from the lands, so perhaps try +/- 0.010" increments depending on your current COAL. |

Brony - Thanks for the useful feedback. I agree that the single flyers are likely me. I will start messing with some of the other variables as you recommend. Wanted to settle on a powder first. I'm still thinking H4895 since I can get more of it. Not so right now for me for RL15. |

Give the 69 grain Nosler Custom Comps a try. I have heard the 68 will not shoot but the 69 shoot lights out My experience has been the opposite. The Hornady 68 has been exceptionally accurate for me in several rifles. I only have one barrel that likes the Hornady 75's. Most prefer the 77 Sierras or Noslers. 24.0-25.0 gr Varget and the Hornady 68 shoots extremely well across multiple rifles |

Search the usual online supply houses, you are almost certain to find them in stock somewhere. |
