.308 criterion barrel Q before reloading

I am wondering if these #'s sound valid.

I have installed my criterion .308 barrel and in the process of getting things together to start reloading for a new caliber (.308 is new to me). I have the hornady L-N-L OAL gauge. I measured 15 times with the same 165 grain hornady SST and I am getting a reading of 2.2435 to 2.2445. The last 10 measurements all being 2.244 or 2.2445. I am pretty confident that this is the correct measurement. However that means that the cartridge overall length is going to be 2.872'ish. Does that seem overly long to anyone. If I remember correctly yhr 1:10 twist criterion drop ins are set up for heavier bullets perhaps explaining the longer throat? If I can find some 175 gr SMK's I will be loading these as well.

Anyone have any trouble loading the 165's out to such a long length? No idea how the extra length will change case capacity except I will have more. Just not sure how much more and if I need to be worried about that.

Just spinning my wheels till the warmer weather gets here. It is 15 degrees here in lincoln this evening.

Load it and shoot it..start with what the book tells you to do and after you have loaded a few then you
do your tinkering around with the O A L if you want..
