Savage model 16 270 WSM to 284

**martentrapper** · 07-23-2021, 12:07 AM

Thinking of turning the 16 into a 284. I assume the 284 will feed in the short action. Speak up if you think I'm wrong. Seen a deal on a 284 barrel that is large shank. Google sites say the WSM savages are large shank receivers. How can you tell if you have a small or large shank action?
Thanks.

Large shank actions have a shorter barrel nut than the standard action. Large shank barrel has a stepped area near the chamber that is not present on a standard action barrel. You might get away with just changing the barrel and bolt head, 284 brass may feed from the current magazine. I'm sure someone with a bit more knowledge will come along and correct me if I'm wrong.

To add to the confusion is you have a bolt that has a different length bolt head and firing pin. It is not as easy as swapping bolt heads and setting firing pin protrusion.

Centerfeed pin is 1/8'' longer than standard
Staggerfeed pin is 1/16" longer than standard

If it is a staggerfeed with control round feed bolthead you have a special machined action with a provision for the standing ejector.

The best option is to swap complete bolts with someone who needs what you have. I could help you out if you want a trade.

Thanks Robinhood. I see what you mean. That is the bolt I have except your pic doesn't have the claw on the right side to grab the case rim. My 16 is a center feed. I definitely have a large shank receiver. The 284 is very similar in COL to the 270 wsm. I ran a couple 284s thru the wsm and it appears to work. I can buy the large shank barrel and get it installed...........so I'm interested in anything you might have to trade/sell to get a working bolt.
Thanks.

If your claw is oriented different than the one in the picture(the ejector is different) Then you have a left hand gun and I can't help you.

If it is in the same location I can help unless someone beats me to it. I will have to look to see what I have available but the firing pin and the bolt head are the main differences. A complete bolt swap minus the bolt handle is way to go. If your finish is the same then the bolt handle is not as critical.
