Holes are drilled, pillars are cut and ready to go. Receiver is clayed and waxed twice. Time for some dinner, then I'll be mixing epoxy.

Edit:
Looks like I'm going to go a 2nd round with epoxy. The area under the barrel (first 1.5") didn't fill. That'll be easy. The rest of it filled nicely and I had only a little bit to mop up when I put them together.

Edit2:
I got it out of the stock (that's always a good sign). The receiver parts and lug came out flawless. The bottoms of the pillars need some epoxy and the barrel channel area is a little cavernous, but I think it's good enough for the time being: 257 isn't really a heavy hitter when it comes to recoil. I'm anxious to shoot this puppy.

Looks good! I hope you didn't bed the area under the safety. That is known to cause erratic groups. I don't bed the action from the bolt handle cutout to the safety tang.

My ongoing Savage experience

Tony.

I floated the tang end of the receiver.

Still have headspace issues firing factory 257 Roberts through the AI chamber. 2 failed to fire.

But.... When they did, they shot alright. 4 groups of 3--1", 1/2", 1/2", 3/4"
Extremely pleased!

Got some brass fireformed and started working up through some 87gr Speer TNT loads with IMR4064. Found magic at 44.0grs (under a half minute for 3 shots). Next up is the 117gr Hornady Interlock.

Still working through some other issues (i.e. making/fireforming brass). Had a misfire with well formed brass that has me scratchin my head.

30Caliber, sweet looking job you did! It looks like after you get enough fire formed cases prepped, you will be able to wring it out. Good Luck!!!

That's where I ended up going. There was evidence of WD-40 useage. WD-40 is actually a very slow-acting varnish. So I got the bolt stripped down, cleaned up, adjusted for firing pin protrusion and cocking stud clearance. Did some polishing on the camming surface. I also flushed the trigger clean with lighterfluid and adjusted it to add a little weight and gave it a little more overtravel because I think it was dragging on the firing pin. No more misfires.

I've never been a fan of Weaver mounts, but I'm warming up to them in this case. I've got a 3-9x mounted and zero'd now, and can swap it with the K10 in the drop of a hat with no loss of zero. Pretty slick.

As far as accuracy goes, the 257 Roberts (Ackley Improved) is living up to its reputation with ease. I've got the fireforming issues worked out--I'm using a 87gr cast bullet, seated into the lands over a normal dose of 2400. Ended up getting a Forster BR FL sizing die because the Lee version was a rough and tough. I'm making cases from 6mm Rem--simply running them up through a Lyman M-die and loading them. I tinkered around with making them out of 30-06, but that was a lot of work just in trimming--and thinning the necks with sandpaper and a drill is also slow. I got a handful done and decided to let it be.

Anyhow, the 87gr Speer TNT does superbly over IMR4064 with no muss, no fuss. Very consistent and well behaved. I got some Hornady 117gr Interlocks for deer (the beefiest bullet locally available at the time). It's throwing some odd fliers, but wants to do well--couple groups approaching a half-inch.

100gr Sierra GameKing and some IMR4895. Should be doing about 3150fps. Dialed her in 2" high at 100yds.

When you can find some try the 117 Sierra flat base, shoots great in my No. 1 with H4831.
