What kind of speeds are you guys seeing with 120-130 grain bullets?  I'm arond 2000fps with a 120 BT out of a VV BBL.  Thanks

I am getting 1800-1850 fps with a hornady spirepoint and 28.5 grains of imr-4895. My Hodgon manual says I should be getting about a 100 feet  per second more but, oh well,

A healthy load of AA2460 (from the Sierra Manual) gives a 140 ballistic tip 1900fps (1940 on a warm summer day) This is a very warm load in my gun but has never given a problem, BTW after sighting it in I only use it for "serious business" . A more sane (and more accurate to boot) load is the Sierra accuracy load of 28.5 gr. of AA2460 with their 130 gr. ssp (pro hunter), in win cases using wsr primers. Gives me an avg 1875 fps in most any weather (odd)  and shoots where I point it... I have 5 times as many of these thru 'er.... Marty
