Understand and agree. thanks for the reply. my 6mm with 1:10 actually handles the 95's but not the 105's. so there is some twist well below 1:10 that is needed to make the 105's stabilize. my 6.5 swede with 1:9 will only handle 130's. it is always a mystery until you shoot them and you get the ugly group or worse, the keyhole
