As a point of intrest I have 2 savage 110s 1 in 308 1 in 3006 . The 308 will shoot max loads from any of my 4 books with 150s no signs and 180s to all but max but throws them all over . My 06 shoots 2700fps with the loads the book says are 2500fps with 150s . I loaded some that should have been about 2750 that hit over 3000 and shot 24" patterns all well within the "book numbers" and never "signed.

Living on the edge with hand loading is dumb, but....................... I did once "hot load" some gold dots in a 357 , not any info for 75 or 85 gr GD for 357 since they are for the 380 auto/9mm kurtz . Lota muzzle flash from 9gr of unique . I didnt have a chrono then . Seating depth plays a huge role in end pressure and velocity my example ; 45colts with a 90% load with an oal change from maximum to minimum showed me 985fps at the longest oal 1180 at the short oal . That is a huge jump in a cartridge with a max of 14000 psi standard and a +p of 22000 psi.

My thoughts , load for cost effectivity and accuracy and if I get a little more than a factory load or a heavier or lighter bullet yea me . It's about shooting more for me not seeing how fast I can make it go .
