Just tested the CCI #450 with this load and side by side at 60*F they both shot 2000fps average, but the CCI #450 has an ES of 28 and a SD of 14. Both group about the same (around MOA or slightly better). |

All feed, fire, and eject fine (to include bolt staying open after last round). SD - 6.4, 11.3, 11, 24.5 velocity spread (fps) 14, 38,34,52 9.5 and 10.2 loads shot at 75F & 30.11; 9.75 and 9.95 77 F & 30.06 All loads were done on my Lee Loadmaster; I had to use the .61 cavity and some sand paper to get to 9.95 and 9.75 (I shot the 9.5 and 10.2 and then determined 9.7 would be right were I wanted it; first .61 cavity I took to much out of, so decided to try it; then did another). For weights I am doing two powder drops and dividing (hence the .05 measurements). The are pretty consistent, but still a progressive; and a Lee. I am going to go with the 9.75 @ 1038 fps load, hopefully keep me subsonic year round. |

Another load I worked up. It was fired out of a 1/8 twist, 16" carbine SOTA upper. I haven't chrono'd it, but it is very consistent and accurate out of that particular upper. I settled on 17.6gr of powder, but 17.8 was just as accurate out of this setup with no pressure signs.

Do not use this load. I loaded 5 rounds, tested them and they were fine. No pressure issues. So I loaded 200 more. After firing 10 of the second batch I had 7 flattened primers and 3 blown out primers. I suspect that my scale was out of calibration but 17.7 was a good bit below Western Powders max for a 168gr. All were loaded on a single stage and powder charges were visually verified after weighing. I'm going to pull the remaining ammo I have and work up using the Hornady data, witch is more conservative. Will also be calibrating my digital scales and using the Dillon beam scale as a check. Lesson learned.....

Maybe you should update your original post. Some may not see this follow up post.

Do not use this load. I loaded 5 rounds, tested them and they were fine. No pressure issues. So I loaded 200 more. After firing 10 of the second batch I had 7 flattened primers and 3 blown out primers. I suspect that my scale was out of calibration but 17.7 was a good bit below Western Powders max for a 168gr. All were loaded on a single stage and powder charges were visually verified after weighing. I'm going to pull the remaining ammo I have and work up using the Hornady data, witch is more conservative.

Here is one I did this week. It was fired out of a 1/8 twist, 8.2" Alpha Shooting Sports barrel on an AR15 pistol. I tried loads in .2gr increments from 15 to 16gr. I shot them at 50 yards with a scope to try their accuracy. This load ended up under 1" at 50 yards. All shots were strung vertically and I discovered that my scope mount was loose. Regardless these grouped better than all other loads I shot. I plan to try them again (with the mounts tight) next week to verify their accuracy.
