Snakeman,
Just recently, I purchased TWO cases of CCI Blazer .40 S&W 165 gr TMJ for a total of $349.00 ($330 for the ammo + $19 for the shipping) from
www.tsssinc.com
That makes it $6.98 per box of 50 -- the cheapest price anywhere unless you work in one of those places, of course. You have to buy two cases though. Since I try to practice a lot, it's fine with me!
The only possible problem with their shipping price is that it may, of course, vary based on your location. Call them first to find that out.
They don't advertise 165 gr on their web site, so call and ask for Khris Wright should you decide to buy it. They do, however, have 180 gr Blazers (also in .40 S&W) advertised there, and its cost ($150 for a case + $8.50 for shipping) is the cheapest I could find as well. It's less than what both ammobank.com and ammoman.com sell this ammo for -- despite their offer of free shipping.
BTW, 165 gr rounds in .40 (at least in Blazers and Speers) kick substantially more than 180 gr, and since my carry ammo is either 135 gr or 165 gr HydroShocks, practicing with 165 gr TMJs makes perfect sense to me.
Hope that helps,
Emin
