10MM Question

Hello all,
I hope this has't been asked allready.
I still have an old box of Hornady 180 grain xtp..Advertised volosity is 1410 fps..Has any one actually chronoed this stuff..
THX in advance

I have not but I suspect it does not come anywhere near this. I have some of the old Norma 170 gr load which is as hot as one would want to get and it is around 1300.

Hey Jim,
Thanks for the response.I thought it sounded a little far fetched,but that is what it claims on the box..Now I use only DT.180 grains @ 1350 fps..

I have found that sometimes Hornady's claims on the box are unrelated to the real world velocity....the first 200 gr XTPs I tried for .45 ACP went 800 fps not 1000 fps.

OTOH some of them are spot on (The 270 gr .376 Steyr gets right at 2600 fps in my 20" carbine....not too shabby!).
