I've never used it. It's too unstable for me. Dig up a 6PPC load with it and start from there.

lol thats the problem, out of all my sources for loading data not finding any for the 748 in ppc or 6br in that class range of bullet weights.
but it is appearing that 748 and bl-c2 are close and meet similar standards such as wc846 and come from the same powder plant. I'm leaning towards starting at 28gr and working up from there

UI shot some 748 in the 6X6.8. Virtually a performance twin to the LBC as it has a lower capacity but runs at higher capacity so they come close to cancelling out.
I shot the 58 and 87's in it. For the 87 I shot up to 28.5 at 2781 FPS. There is a bit more room available on that one. The 58 was over 33.5 of 748 showing 3550. Both were in a 20" barrel.
I only shot BLC(20 in and American 30 and it is not a good translation point. BLC(2) suffers from temperature issues like 748. Across the board I have never had that great of results with it in any loading I have used. I di use 748 a great deal in the 6X45 with 87's for years but that was way before I got the knowledge I have now after dealing with wildcats and leaving for a state that 100 is the temperature you START to shoot at..LOL

I would start at 27 myself. If you're tapping your way through a minefield it's no time to be in a hurry. Remember they aren't called wildcats for nothing.
