I have several model 12 Savage bench rest rifles I just had the chance to buy a 25-300 WSM barrel and all the reloading accessories for a real good price.
Here is my question I have an extra bolt that has the small bolt face and I got the parts to convert it to a magnum bolt face but it is .1220 longer that the other bolt faces. Is it OK to just not thread the barrel in as far or did I get the wrong bolt face/ It is a short action.
#1 You must achieve headspace.
#2 Your firing pin is too short for the longer bolthead
#3 you either need a magnum firing pin or
you will need to order a SA WSM bolthead that has 7/16 long lugs
Thanks for the reply
I have changed many barrels and know about headspacing.
I did change the length of the firing pin and set that to .035".
My question is did I get the wrong bolt face I ordered a short action mag bolt face from Midway.
the one I got measures .5580" and the other ones I have measure .4360".
Question is would it be safe to set the headspace on the longer bolt face doing that would put the barrel out .1220"
Absolutely you can back the barrel out the 1/8".
Did you change the firing pin or did you adjust the stop in the old firing pin to set the correct protrusion?
Thanks Robinhood for the info I adjusted the original firing pin to a .035 protrusion.
It is hard trying to see which bolt face is correct maybe someone on this forum might have a complete magnum bolt that they might want to sell
I would rather have complete bolts than having to change bolt faces
I have the following barrels for my 3 Savage model 12 BR rifles
204 Ruger
22BR
6mm BR
30 BR
223
25-300WSM just got this one
6mm Dasher
I have other custom BR rifles but for the money Savage does a great job at accuracy.
I would not be surprised that the additional 1/8" compression of your firing pin spring make the bolt lift much harder.
