110 SMK - Load Data?
#1
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?

I've tried Berger 109's which have about the same BTO numbers your getting. I would have to check my notes but the charge weight using LVR seem about right. I got better results with Hornady 105 BTHP, the juice wasn't worth the squeeze, but every gun is different. My guns favorite bullet is the Berger 90gr Target, but if it's windy and I'm shooting 600 yards and further the 105's might do a little better.

check Hodgdon's data online

top charges with 110gr Hornady ATips @ 2.26" are 28.2gr with CFE223, 28.2 with Lever, and 28.4 with AA2520 at gas gun pressures

You COULD "window" a mag, meaning cut a slot in the front to allow a longer OAL.
