It is best used for heavier bullets. While it will work for 55 grain bullets, you might not get good uniformity of velocity. I've tried it 20 years ago for 65 grain Winchester PPs, wasn't impressed.
But for 75 + grain bullets, it is decent. With 80 grain Sierra MKs, it is under 2" at 300 yards. |

I got 24# of it coming since well...that's about all I could find in stock :-) Looks like it will work for both my 223 and 30-30. Can't wait to try this load. 2520 62 MIL M855 23.9 2,855 26.5 3,127 54,367 2.260 also picked up AC #7 for my 9mm / 10mm |

It's a medium fast, double base, ball powder, so it should meter well . They use it in their 223 Rem testing, but only up to the 69gr SMKs. It's an older pamplet. Chris |

The case head is bent due to forced extraction. As in beat the carrier out with a brass drift. Fractured the bolt axially in 3 places:  The 3 rounds fired before this were printing a tight 3/4" group. At 300 yards. Until the 4th shot destroyed the bolt and magazine. I'll have to look around for a copy of the group I have stashed somewhere. |

I've used 2230, 2460 and 2520 in 223, I had good luck with all three, I didn't really see any difference in group sizes with any of those on the 55 gr bullets I was using. I finally settled on 2460, but there was nothing wrong with 2520 at all.

Looks like head case failure. Ill be using LC since I'm looking to load some ss109 to combat loads |
