I am shooting a 300 WSM. Bullet is a Sierra 155 grain Palma at 3200 fps. BC is suppose to be .450. I have a 25 minute base to put on the rifle, but as of yet I have not put it on the rifle. I will be hunting with the rifle out to about 600 yards. We have a 1,000 yard range that I would like to shoot, but I need to figure out if I need to install the new base.
If I have a 100 yard zero, how many minutes will I need to hit center at 1,000 yards. I have tried a couple of ballistic calculator's but I can not seem to get it right. Could some one either run this, or point me in the right direction to a ballistic site where I could do it myself(easy site).
I will probably be zeroing the rifle at 400 yards when I hunt with it. That way I can dial down to 200, and 300. Or dial up to 500, or 600?? Thanks, Tom.
