Default Seating Depth???

I need help with my seating depth…

I recently inherited my Grandfathers 1979 Browning BBR .300 Win Mag and I am trying to work up a load for my upcoming elk trip in October.

I am shooting 200 gr Accubonds and Hornady brass. I checked where my bullet is contacting the lands and it shows it is touching them at 3.653”. Here is the method I used to check the depth: http://www.youtube.com/watch?v=J1yBCarMgZQ

Problem is, the Nosler recommendation says max C.O.L. is 3.340” and the max length my magazine will hold is 3.370”.

If I set the bullet at 3.370”, that will but the bullet .283” off the lands. That seems pretty far to me….

What would you guys do?? Any recommendations would be helpful.

Default Depth

Unless you want to us it as a single the magazine/clip is the controlling factor. You will have to find the load that shoots within your accuracy tolerence at that C.O.L.

Default Seat em

This is not unusual. Just seat them to the magazine length and varying powder charges should still result in good accuracy. Had the same issue with an A-Bolt in 270 Win. Got great accuracy with that rifle so turned out to not be a problem. Just load em up and shoot the load your rifle likes the best..

Weatherby's are known to have a lot of free bore. I would work my loads from the factory COL and out to my maximum magazine length and find what your rifle likes best.
