Re: Weatherby Action Length?
If it is a mk 5 with standard freebore it will take an extremely long heavy bullet to reach the lands and not run out of the case first. You can get a gunsmith to change it though and allow you to seat the bullet way out there. He would have to lengthen the channel in the bottom of the bolt to 300 wby length so it would go back for enough to pick up the longer rounds. Also take out the 257,270, 7mm magazine and install the one for the 300 and 340 wbys. That is easy, you can do that. But need a lathe to cut the bolt channel. I have done the 7mm wby's from a 300 wby and they have the ability to seat the bullets way out there. You would be changing yours from 7mm to 300 basically except for the barrel. Should not be very expensive at all to make that little cut that will allow your bolt to slide back to 300 wby length. I build everything I can on the wby mk 5 action because it is far and away the best action on the market for custom work unless you get a custom action. I look for the wby synthetics at used prices and pick them up in the $400-$500 range. I love these guys on the forums that run down these actions and cause guys to dump there mk 5 actions for nothing. I have benefitted greatly from that and strongly encourage all the wby bashing they can bring. Saves me a lot of money to get the best there is out there.
Predictions are difficult, especially when they involve the future
