Being both ends of the barrel were cut, there was no chamber end designation, and I wanted to be sure of getting rid of the drilled scope block holes in the barrel, during the tapering process, without having to turn down the barrel more than I wanted to. I could wiggle a .301 gauge pin ever so slightly in one end of the barrel, so that looser end was to be my chamber. It worked out that the drilled holes could be gotten rid of, while maintaining the taper I wanted.

Next, lots of measuring here. Due to the limitations of my lathe's headstock, most work was to be done on centers, like the Ruger's were. I used the old barrel for a guide, for thread pitch, shoulder, and consideration for the recoil lug. I tried to do something a little different here. I planned to have the case headspace on the shoulder, rather than the rim. Probably a fool's errand, as after firing a case the first time,that is accomplished anyway. After alternating, touching up the barrel shoulder and chamber face, it looked like I was in the ballpark. My goal was .005 clearance between the rim and breechface. The finalization will be later.

Now the reaming begins. Run slow, cut a little at a time, clean the chips often, use lots of cutting oil, NEVER turn the reamer backwards, and finally, have the lathe stopped when inserting or removing the reamer, to avoid scoring the chamber walls by errant chips. One other thing, I inquired about purchasing a floating reamer holder. My mentor said no, I was to loosen the three bearings on the steady rest, ever so slightly, after the reamer was started, with the lathe running. This would allow the pilot to find it's own center, eliminating the need of the floating reamer holder. Some may disagree with this method.

Now for the touching up of the chambering. I stripped the bolt, and screwed the receiver on the barrel, making it snug. I used a live factory round to set up the headspace. Not recommended, but I had no headspace gauge. The bolt was stripped anyway, so I felt secure. I was close on the initial reaming, but the bolt would not close. I put a dial indicator on the tailstock, reamed some more, and got things even closer. I put an extension on the reamer, and manually turned the reamer half a dozen turns, blew out the chips, and popped in the round again. Almost there. Measure twice, cut once, as Norm says. Repeated again, until the bolt closed with the slightest resistance. With the receiver removed I could just see daylight between the cartridge rim and the breachface. Close enough.

I did the same tapering treatment I did for the Ruger. Drawing out on a graph, the diameters by the inch, for the taper I wanted. On the metal lathe, I reduced the barel diameter in steps, to blend in later, using a disc grinder with a flap disc. After a subsequent spin in the wood lathe, (reasoning explained on my Ruger build post), my blended taper was achieved. The already balanced faceplate and drive dog were made already, making the job a snap. I needed to do an extractor cut in the mill. Getting the clocking right was a little tedious, but it was completed with no blood loss. An 11 degree muzzle crown was also added.

The new barrel was as of a fatter taper than the factory one was, so I had to break out the barrel channel rasp, to fit the new barrel to the existing stock. With that together, i just had to shoot the darn thing.

I put on a heavy coat, welding gloves, and a machinist's face shield, and headed out back. This was August, not January. If anyone saw me, they would think I was nuts. I wasn't taking any chances. I must have looked like Neil Armstrong on a moon walk. Anyhow I fired two factory rounds into the berm, proofing it, without incident. The two cases extracted easily, and looked OK, so I was good to go. To date, they were the only jacketed bullets fired in this rifle.

I cold blued the barrel. It looks decent, but nothing spectacular. Next to replace that ugly stock.

I found a laminated stock at Boyd's that I liked. Nutmeg was the coloring pattern. It cost around $100, plus shipping. I learned that the 788's had several action screw spacings, dependent on caliber. I had to make sure I selected the correct one. The stock arrived in a week. The barrel channel was cut to the factory barrel dimensions, so a little rasping was in order for the replacement barrel to fit. With that done I noticed interference with the magazine. A little relieving there, resolved that issue. Things are starting to look up even more now.

I wanted to stamp the caliber designation on the barrel, but I didn't trust myself to get the stamping straight and presentable. I learned of a local business, that does laser engraving for trophies and plaques, who just started doing firearm engraving also. For $25, they laser engraved the caliber on the barrel while I waited. Looks nice.

I mounted a spare Leupold 10X silhouette scope, with a 1 min dot. A Weaver mount and rings came with the rifle, so I used them. I bought an extra magazine from Numrich. I thought I'd mention, that the 788's chambered in rimmed cartridges are unique, as they have two piece rotating bolt heads. This sort of makes these rifles special.

Now to load some ammo. I sized some once fired cases with my RCBS FL sizer die. Guess what, they won't quite chamber. Close, but no cigar. Turns out the factory ammo shoulder is set back a little more than my die allows for, and that's what I set the headspace by. Off to the bench grinder with the sizer die. After relieving a few thousandths off the bottom of the die, and readjusting, the shoulder is adequately set back now. After the cases are first time prepped, a Lee collet neck sizer works quite well. No more lubing mess. Lots of reloading with mid power loads, before FL sizing needed.

I have a lifetime supply of 4759, which I use in all of my other cast bullet rifles, 30 cal up to .458 with satisfactory results. This will be the powder I will use in in this rifle. I will start off with the 311291 bullet also. After initial testing I settled on 15.0 grains for a velocity of 1550 fps.

Groups of slightly over 1 inch, are common at 100 yards, with the 311291 bullet. Can't seem to do too much better. I do notice some occasional bullet tipping at that distance. Upping the velocity to boost the RPM's, or going to a shorter lighter bullet are my two options for the 1-14 twist barrel. I went with the shorter, lighter bullet, a Lee 309-150. Shoots pretty good with the same 15.0 gr 4759 load. More consistent than the 311291. Nice round groups. 10 shots, under an inch. This bullet seems better suited for the 1-14 twist barrel. Good enough for my needs.

I have been recently experimenting with powder coated bullets. I have not fired enough of them to say if they shoot better than the alox ones do. The bores are spotless and easy to clean. I learned that powder coating builds up the diameter of the bore riding nose of the bullet, often making chambering occasional rounds difficult, if not impossible. Inconsistent coating thickness is part of the problem. I tried making a bullet nose sizer for my Lyman sizer. I sizing up to the front driving band. It works, but the sized metal has nowhere to go, and leaves a bulge at the front driving band. Resizing the whole bullet gets rid of the bulge, but the bullet is apparently damaged, as they group poorly. I gave up on this idea.

The factory trigger was fair, but not great. I swapped out the trigger spring, which lightened it somewhat, but still not great at 3lbs with some creep. Brownell's had a sale on Timney triggers, so I purchased one. In attempting to install it, I noticed that the holes in the trigger block for the roll pin, which attaches to the receiver tang, were undersized. .090 is the size, by my pin gauge, and .096 was what I needed. I used a #41 drill in a pin vise to ream out the holes. No problem. I have read several reviews on this trigger, with several saying the hole was too small for them also, and had to be enlarged. Be very careful when driving in or out the roll pin. Be sure to support the receiver tang when pounding. The tang is small and if it breaks off, you are in deep do-do. Better have a TIG welder handy. The stock needed a little relieving for the safety to operate freely. Finally the bolt stop on the new trigger was too short. You could feel the bump on the rearward travel of the bolt. Not enough to stop it. If you were too energetic, the bolt would leave the receiver. A call to Timney had a longer bolt release on the way. While talking to the young lady at tech support, I mentioned the undersized roll pin hole in the trigger block. They were unaware of this. Apparently they don't read the reviews.

The new bolt stop arrived within a few days. It was .060 longer than the original. It was way too long. I could not even get the bolt in the rifle. Using trial and error, removing .030, while keeping the stop's contour, I was in business. It appears the underside of the bolt, that the stop contacts, was hammered over the years, which likely caused this issue.

I set the trigger to a nice safe 28 ounces. Nice and clean. Far better than the Remington factory trigger. Very pleased, might even be able to go lighter.

The final specs on this rifle are 24 inch barrel, and with laminated stock and the big scope, weigh 10 1/4 lbs. Not exactly a walk around woods rifle. Total weight was a little heavier than I expected. A lighter scope might save 1/2 pound. Sometimes the rifle just lays there on target, other times it is a real struggle, with a big wobble area, while shooting offhand. I am not in the shape I used to be. This rifle was built to be an offhand shooter, not a bench gun.

I just added a 4 inch gong to my shooting range, to compliment the existing 6 and 8 inch gongs. The 4 incher will be a real test of my offhand shooting skill. Any misses will not be the rifles fault.

In summary, I am quite pleased, with the overall result of this project. Lot's learned, and experience gained. Currently, unless further load development is done, it will not win any CBA matches, but one inch groups at 100 yards, using unsorted or inspected bullets, and a dedicated powder, is not a bad start. Good enough for now!
