Re: 308 and 7mm trajectories and drops
The new Sierra <font color="blue"> 15 </font> gr match king is used by the 7mm varmint hunters to shot the fleas off a prairie dogs ear at distances of about 30 ft. The bullet has a sectional density of 0.003 and a BC of 0.00056. The fact that it has any BC at all is miraculous and that is why all of us 7mm shooters call it a high BC bullet. Once you get to shooting larger game like toad frogs you should use the Sierra <font color="blue">15 </font> <font color="red"> 0</font> gr MK. Of course if you are like me and not as fast as you used to be the toad frogs will get on out there a little ways so that is when I switch over to the larger Sierra <font color="blue"> 1 </font> <font color="red"> 7 </font> <font color="blue"> 5 </font> gr Mk with a BC of 0.6.
A little humor for you Dave and no insult intended.
In a 1-9.25 twist both the 168 and the 175 SMKs will shoot well. If I was talking about a long range 7mm I would be include the 7mm Rem mag, a 7mm Wby mag, a 7STW or 7RUM. News from Kirby has been a little slow lately on the 7 Allen mag, but intitial reports were good.
