Will the 1-12" stabilize the 190 SMK? I have 3 boxes of them but my current 308 hates them. I also have a couple boxes of 185gr Bergers.
My 12 twist does. Actually getting good results with CFE223 under them too.
At my altitude the 12 is also on the edge for stabilizing a 208 amax. I have read of it being done successfully.
On the other hand my 6.5 project should be on the go in about 3 days once the bedding hardens and I finish the inlet for the mag.
