does know if the tmk have better oal consistency then the smk hollow points
This will be the difference- plastic tip length-If you are measuring base to tip, probably a little. The plastic tip is most likely a bit more consistent. But, ideally you'd want to measure from base to ogive and remove that variable all together.
I had the exact opposite results.I tested the TMKs and they shot nice "round" groups. I then shot the SMKs and the groups were tighter than the TMKs. I stuck with the SMKs.
