I don't have a chrony, could I get some of you guys to tell me what velocity you have gotten out of this load for a simple load velocity estimate. The load is:
71.0 gr 7828
200gr Sierra Matchking
CCI 250
out of a 26 inch tube
Sorry about that, it is a 300 win mag.
Thanks

You will not be very far off from what the manual tells you for the load. They usually tell the length of the test barrel so if they used a short barrel you could be a little faster and they used a 26 like yours you will be close to the book.

Actually my experiences do not agree with yours.I have seen over 150fps difference between the velocities posted in loading manuals and the velocities actually produced in the rifles that that I have chronographed the loads in.This was with the exact same components and the same barrel lengths.

I agree with stubblejumper here.....often the books are very much in agreementment with my readings.....and then sometimes there's hard to explain differences.
