[QUOTE="SMK1000plus, post: 1622809, member: 93846"] What is your rifle's measurement to the lands and maximum useable magazine well length? Your 1 in 8" twist rate bore 300 Win Mag is best suited for nearly any Cup-N-Core bullet with the typical length of a 210gr and up weight but, really shines with the monolithic bullets like the Hammer Hunter of 181gr, or up to the 214gr, provided you have the distance to lands and magazine well clearance necessary. You'll be hard pressed to find better long range terminal performance than the Hammer Hunters, without significant sacrifice of close range performance. The .308" dia. 214gr Hammer Hunter is deadly and has a very high B.C. (G7=0.322, est.) but, is very long (1.752") and needs a lot of throat and magazine length for proper seating depth. The 199gr Hammer Hunter also has a very high B.C. (G7=0.299, est.) and is a little shorter (1.618") but, is still a very long bullet. If your clear magazine well and distance to lands measurements are typical of most 300 Win Mags, then the .308" dia. 181gr Hammer Hunter with its length of 1.524" is the ticket. The G7 B.C. is a respectable 0.272 but, at least some of what you sacrifice in B.C. with this bullet, you will make back up on the higher obtainable velocity of its lighter 181gr weight and you will still get excellent penetration and terminal performance, even at extended ranges.
