| I'm under the impression that BL-C(2) powder is well suited for bullets in the 70 grain range - yeah or nay? Thanks. |

IMHO, BLC-(2) gets spooky at higher charge weight and higher temps.
I feel there are better , more temp. stable powders available for heavier .224 bullets I have experienced BLC-(2) max-ish loads show signs of pressure with even a 20 degree ambient temp. increase... all of a sudden there were all kinda pressure signs on the brass that in the cooler morning temps. were not there. Soooo... I just use different temp. stable powders. |

It has been listed in the Sierra manual for many years. Depending on your application of gas or bolt gun, it doesn't carry as well into the heavier loads. Not impossible, there are just better options.
By comparison, if you look at the Sierra load data, you will need roughly 2 grains more at the higher ends of the load ranges to achieve the same velocities as the RE-15, Varget, etc. No that this is any problem mind you, but I just find the slower powders easier to deal with. The Sierra manual drops BLC-2 after 53 grains in the AR loads.

I picked up 4 lb's of CFE 223 from Bass Pro yesterday, I haven't used it yet but plan on using it with my 75 gr OTM loads instead of Varget & RE-15 because I prefer a ball powder.
Any of the new ball powders coming from St Marks are much more temp stable than the older ball powders, this includes CFE-223, Superformance, LEVERevolution, Alliants new Power Pro powders(2000MR is supposed to be great with heavy 223 bullets), and a couple of Accurate powders(AA2200 & 2460 for sure).

Quoted: I'm under the impression that BL-C(2) powder is well suited for bullets in the 70 grain range - yeah or nay? Thanks. If it's all you have or can get, yes you can use it. Just don't load to the max, and don't leave your loads out in the sun for hours before shooting them. That's what causes the reported problems.
