Here's a dumb question.  I just got hold of some swaged 2018 Easton Classics.  The only points I have on hand are 11/32 and seem just a hair too big.  Will 5/16 points and nocks work?  How about broadheads?  Thanks.

5/16 will work just fine and I'd suggest that size for nocks... I prefer a nock that's a touch small.

You can get 5/16 broadheads, but I wouldn't worry about that size. I'd go ahead and order whatever you prefer in 11/32.
They'll work just fine.  

Thanks.

I also use the 5/16 nocks on 2016 and 2018's.
The gluse should take up what little space there is between the Broadhead and shaft....

2016 is 20/64" OD. If you do the math, that works out to 5/16". 11/32 will work fine for the broadhead, but will be slightly larger than the shaft. Some say that will increase penetration.

Luck!
