Is anyone using BL-C(2) in the Brit? Or tried it? It is listed as producing the highest velocities in the Brit and some other cartridges at what seems the lowest pressure. I'm interested in lower pressure, not necessarily the highest velocity. I'm currently using AR2209/H4350 and with that powder I am getting very good accuracy so I'd only want to change if there was no loss of accuracy. A slight gain in velocity won't hurt either.

Don't know what bullet you're using ,no matter, any of the 4350s is going to give you less pressure in the .303 than Bl-C-2 ( WCC846). roger

I'm using 180gr Highland (PRVI).

It's the loading charts that show BL-C(2) to give the highest velocities in the Brit and a few others.

303 Guy I haven't used any BL C 2 in the 303 but I have used W760 and H414 with 180 gr .I have found best accuracy and low pressures in several SMLE's with W760 which gave very good case life. When loaded to higher pressures in a P-14 W760 gave me the highest velocity with V good accuracy. I've found W760 to be very consistant even in low pressure loads.

FWIW Of all the reloading manual data I have The 180 grain bullet pushed by 44 grains of Accurate 2520 yields a pressure of 45000 psig and the highest velocity of 2568 fps. Win. 760 yields 46550 psig. and a velocity of 2435 fps. roger

Thanks. I'm a pretty conservative loader and like to see some roundness on the primers. My reason for looking into ball powders and slower ones is that the AR2209/H4350 I'm using doesn't quite fill the case but more importantly, it peens cast bullet bases badly. So, I'd like the slowest powder that will produce the highest velocity with the lowest pressure but is also consistent at lower load densities for use with cast. I'd rather use a powder that doesn't produce full pressure with a full case than one that requires empty space to keep the pressure down.

Different ball game ole buddy. 180 grain cast+++++ 28 grains XMp 5744, 41000CUP, 2160 fps. or 37 grains XMR-2015 41399 CUP 2350 fps. Roger

BL-C2 is a powder I stay away from.
I like powders that are flexible enough to use in several different round with different bullet weights. BL C2 worked ok in my 30-30 and was very accurate in my .222. But it resulted in black cobwebs growing in the .222's bore a week after I cleaned it. In a 270 it made a 3 ft diameter muzzle flash with a 90 grain Sierra. That was back when it cost $2.97 a lb. I found other powders i like better that did't do any of those things.

If you use a .303 Lee-Enfield at max pressure it will eat your brass.

Interesting. I stay away from hot loads in the Brit which is why I asked about the BLC(2). I see in the reloading manuals it can prduce good velocities at lower pressure in one cartridge then high pressure in another. I'm going to pass on that powder. I notice too that ball powders have a way of skyrocketing in pressure at the top end of their loads. I found this with a ball powder in the Brit many years ago with velocity readings and primer flattening. Stick powder would produce a fairly flat velocity/powder charge curve while the ball powder had a pronounced curve.
