Follow along for my 25 PRC build

Since I received notice from preferred barrel blanks that my barrel should be shipping soon, I have started the wheels in motion to get parts together. The 25 PRC is still a wildcat, so parts and components involve some improvising. First things first, I chose a savage 110 receiver as a base, and a year ago I had bought a synthetic stock 110 from buds in 280AI and as usual didn't read the fine print (or maybe there wasn't any to begin with) and didn't notice it had both a bottom bolt release and smooth barrel barrel nut--along with savage's teensie extractor-- my least favorite aspects of their firearms and really wish they would improve or get rid of altogether.

I tried spinning off the action with an action wrench--but that didn't work because the barrel nut just spun along with the action eventually locking it, so plan B was to put the action in a receiver vise and use a pipe wrench on the barrel nut. That worked easily and the nut came right off, though distorting it but who cares, I would never reuse it anyway.

Because of the accutrigger's bottom bolt release and the likelihood I'll run the COL's of the cartridges pretty long (and also the fact I already have one)-- I decided to base the build in an MDT chassis which dispenses with the bottom bolt release silliness in a savage for the simple side slot and the ability to load cartridges long in an AICS magazine.

Be it ever so humble, here is the start:

Ok, Savage 110.
But then ya lost me....
How does an MDT chassis change a bolt release?

IF that 280AI barrel was 24", it needs a propper home in PA.
Prefferably at my house!

Quite simple, really, they simply cut a slot in the side of the receiver which exposes the sear bracket, all you need is something like a hex key to reach it and pull back. Not quite as handy as a built-in bolt release, but still an improvement over the trigger guard bottom-release IMO--plus the chassis will still work with top-releases.



As for the barrel, it's little used, but I think I'll keep it as a back-up since I do have a 280 AI build. Sorry bout that.

Next step in receiver prep; truing receiver face, receiver barrel threads and receiver lugs with PTG raceway piloted reamer and replacing recoil lug with thicker magnum type lug (though probably not necessary). Test fitting of a barrel and receiver--without any lubrication or anti-seize applied the barrel threads on smooth as silk. Getting Savage's "micro-bead" thread locking out takes quite a bit of work, especially if you pre-heat the barrel nut since I'm guessing it's made of some kind of plastic judging from the melt and flow I discovered--but that's speculation on my part.

I found 4 boxes of very expensive 6.5 PRC factory ammo--I had no choice but to pay what amounted to $3.75 per cartridge and empty them just for the brass. Now I have to get the right bushings to neck down for the .257 bullets.

Just curious. How much do you want for those 6.5mm pills?? Got that PRC I am building, and could always use components.

Want to talk price? PM me.

Word to the wise--there is a slight ring on the some of the bullets where it was gripped by the collet remover, even the ones that don't might be altered--in other words you may not get consistent stability from them. PM me if you're still interested. (more than happy to trade for brass!!!)

I checked tacticool out--and I don't like their reputation and I've checked your other "usual suspects" as well and still can't find any that's actually in stock. In the meantime I completely forgot about needing a .25 caliber expander for the sizing die.

I do--but these days many listings are dead or not up to date.

So, what looks like leftover shot blast is a thread locking system?
What the heck!??!!

And, yeah, i'll agree. It was a PITA getting it all out of the Axis action i'm using for my bench rest build!
Even worse was getting it off the barrel so i could unscrew the nut getting ready for sale.

I don't know what the stuff is--but I've taken apart enough new unfired savage rifles that I'm pretty sure it's not residue from firing or production debris.

Necked down with a .282 bushing--easy peasy with the prazi, I'm loving the Prazi more each time I use it. I'm going to wait until the barrel comes in and I get a better idea of what the chamber is like before I fiddle any more with the cases. Just found and ordered some 120 gr Seneca bullets from Patriot Valley. Fedex has lost track of the Bergers I ordered last week and they have no information where the package may or may not be.

The two hundred Lapua cases for minimum bid of $500--or buy now at $550? I think I actually do come out a bit ahead buying factory ammo and taking it apart once you calculate the costs of the bullets and primers separately from the cases. I filled a 1lb jug with about 11 ounces of the powder out of 80 cartridges.

With the price of primers now you most likely do. Anyone that has them under 15 cents a primers don't have any.

I'm about to run out of some of my most important powders--and after 2 years there's been little change in the availability (lack thereof) for primers. I'm thinking this could go on indefinitely, so there's an obtuse logic that it might be better to buy factory ammo now.

Finally got a trace put out by Fedex and they found the 135 gr Berger bullets somewhere in Connecticut--so presumably they will make it to me soon. I already ordered "back-up" from Midway and PVA so it looks like I'll have plenty of bullets--probably last the life expectancy of the barrel.

Squeaky wheel gets the grease--my 135 hybrids showed up today after I got a trace put on the shipment. Up until as recently as a couple years ago I would have never imagined a bullet like this in .257
