I have noticed that blc-2 gives more velocity with less pressure than any other powder that Hodgon tested. How can this be?

I'm just wondering if this is as a good a combination for the .303. I wonder how accuracy would be and if a magnum primer should be used.

Rifle is a Lee Enfield.

I fell for this trap!

Rather, I should say, it serves as another example that every rifle (firing platform, rather?) is different.

In my rifle, I got the complete opposite results, with the addition of the powder leaving things dirty. I was not pleased, to say the least, because I had done a good bit of research before committing to the buy. I think I still have the cannister, though I know a friend who is interested in buying it.

I'm sure there are other people who got similar results as the Hodgdon's site; sometimes people are lucky enough to find that right combination.

Edit: I forgot to mention that I use magnum primers, and my rifle is a mid-war production Lee-Enfield No. 4 Mk. 1.

I like BLC-2 in the 30-30. I use H4895 mostly in my No1 Mk3. It is an all matching 1943 Lithgow.

BLC-2 is a good powder though. I don't use Mag primers. Just your regular LR primer.

BL-C(2) gave me excellent accuracy in my No1 Mk III Lithgow

I also had good luck with Reloader 15

BL-C2 was the surplus powder Hogdons bought after WWII, and it was the powder used to load in British .303 cartridges manufactured by Winchester for the British government. (the U.S. did not manufacture cordite powder)

BL-C2 gives more horsepower in many calibers. ;)

Read the last page item 7, aircraft machine guns were to use only single base powders to give longer barrel life. Cordite powder loaded ammunition was a hot burning double base powder and was used for Enfield rifles only and NOT for machine guns. The Winchester BL-C2 was a double base powder and much cooler burning than cordite, the BL-C2 loadings could be used in aircraft machine guns in a emergency.

NOTE: At 43,000 cup the peak flame temperature is reaching the melting point of modern barrel steels, the .303 British is rated at 45,000 cup or 49,000 psi and at these pressures with BL-C2 it is not a barrel burner
