so i went to the local fun store this morning looking to stock back up on H335, but what do ya know, all sold out  Ok, so ill grab some Varget, nodda.
They had 15 1-pound containers of BL-C(2), and it was even marked down from $24.99 to 19.99 so i said what the hell and bought 4 pounds of it. So is there a reason the shelf was full of this powder and this powder only? Everything i have read about it so far today claims it to be a great powder, better accuracy than H335, lower pressures with higher velocities, and it meters just like H335. Anyone have any comments on it? I will be using this for .223 in an AR 5.56 16" heavy barrel 1&9 twist ,pills will be 55gr FMJ, Z-MAX, V-Max, Hornady SP |

Quoted:
BL-C(2) was a staple for .223 Rem ammunition for a couple of decades. It has a reputation for sensitivity to high temperatures, as in generating high pressures. That means a person should leave some headroom if load testing during cool weather. So i guess your saying since i live in Texas and its almost summer time, i shouldent load this to Max or even a little over

In Glen Zediker's book "The Competitive AR15" he points out BLC2 for particular attention, unfortunately it isn't a recommendation, in the entire book he only warns against one powder for 223, and that's BLC2, he calls it "spooky under the sun", not exactly a glowing recommendation! If you want to use it, it's temperature sensitive so keep your loads on the moderate side. http://fulton-armory.com/thecompetitivear-15byzediker.aspx |

I've heard the warnings on BLC2 about temperature, but never had a problem, even on hot days with ammo warming up in the hot sun. Nor has anyone else I know. Nor do I see a lot of first hand accounts on here of problems. And I load pretty warm loads. Not sure if that book author got a bad lot or what, but all my first and second hand experience has been very positive. This was my main staple powder for years, all the way from 55 gr to 75 gr match loads.
Would be still, but switched to Varget, which also serves my Garand match loads, as my one powder for all. |
| I use it in .308 and haven't noticed any problems with our Texas heat yet. I worked up this particular load in November and chronographed it then in about 50 degrees. Im gonna chrony it again when it gets good and warm to see how much of a difference there actually is. Like you said its going to be only a week or so before it gets HOT. |

I have used BLC2 in 223 with good results. 55 and 62 gr FMJBT's.
But then I don't leave my ammo sitting in the sun before I shoot it. Black rifles, mags, etc. in the hot Texas sun can get up over 140F just lying there (too hot to pick up without gloves). Just carry along a white towel to drape over your stuff when it is not parked in the shade.
