I have some 110 SMK for my 6mm creed and would like to see if they will work for 6ARC. Anyone try these? What powder and load data. I'm looking at either LVR or possibly AA2520.
I just built an upper using the Rexus 20" barrel 6arc and I am currently measuring the jam on some of my projectiles. For me, my 110 SMK jam Ogive to Base measures 1.697 that puts the COAL out to about 2.354. At mag length 2.28, that would give me about 70 thousands jump.
For the fun of it, I put 27.9 grains of LVR into a fired 6mm arc cartridge and inserted the 110 SMK and measured the actual length at 2.26 which I would consider to be 100% case capacity at magazine length.
I am not sure if 27.9 grains would be too hot, but it would be nice if it worked. I believe part of the challenges we face with LVR, being dirty, moderate ES are due to not filling the case enough. In my experience LVR works best at near 100% case capacity.
Anyone running the 110 SMK with LVR?
