I fired my .577 NE project rifle today for the first time. I fired nine rounds, all that I had ready to go. The charge was a light one to start off, 100 grains of 4064 with 555 grain cast bullets. It functioned well but split it's butt stock lengthwise at the wrist. I didn't like this wood to start with and this is a good excuse to put a nicer piece on it that I have on hand courtesy of Rockchucker. No real mechanical issues which is surprising because the extractor was a nightmare to get cut right. The recoil wasn't all that bad, a big bore for sure, but not nearly as bad as others I've used in the .45 and .50 range with heavy loads. The rifle is long and heavy though, it has 36" of 1 5/16" untapered barrel and it weights a good 15lbs. I found today this dampens recoil as hoped but it's at the limits of what I can hold offhand and shoot. No sights on the rifle yet, so no test of accuracy. It threw a 20lb. propane clylinder well up in the air from 20 yards though. Impacts were impressive. It's finally getting to the fun stage.

There's an understatement! I guess we have a new big boy on the block.:D
 
I don't know the velocities at this point, anything I gave would be a guess. I am not pointing this thing without sights at my chrono either, I've made that mistake before. I do have pics, but for some reason I am having trouble getting them up to my site. I will get velocities when I work on loads and get a sighting system in place.

Rub,
Not hardly, mine is a single shot made on a Riedl action. The block goes up and down on gears between it and the lever. They were only made during the early 70s and it seems not very long. Mine is #42 and it's the highest serial # I've been able to find. It's a huge action, I wish more were available. This one sat unfired and unfinished in .375H&H for many years, until I got it. Today is the first time this action has been fired since it left the factory and likely ever as it was an action alone. I am not into in nearly that price, but it's totally unfinished at this point, just a monsterous barrel hanging off of an action with a rough unfinished stock that will go in the trash. It needs better wood. I will have it finished to suit me, but I have to decide yet how to finish. It depends on recoil to some extent and how light I dare to go. The bluing and wood I will send it to someone for.

Ahhh....'cause if you were buying $35,000 guns, I was going to ask if you wanted to adopt me as your son:D
Good luck with the rifle. Sounds like fun
 
Oh man I so do want to see pictures and range test posts on this puppy Casull. Bestest CGN project of the year :D :D

Now what's up with this watzit gear driven rolling block :confused: :cool:

Me likes:) :) That's officially the biggest tube I've seen on a 'sporting' rifle...

edit to add, I wonder if you're going to need a laminite stock to stop splitting the wood ??
 
That small round in the pics is an 06. It's hard to get a perspective on the size of this thing in the pics. When you pick it up, it balances like a big muzzle loader in my feel at least.
 
I was just talking to someone about this rifle and told them that the barrel looked like a sewer pipe. A nice shiny clean sewer pipe, but one you could possible crawl through.

He got the barrel screwed on there pretty quick too. I was there what, two and a half weeks ago? You gonna take on turning that big round tube into an octagon as your next 'smithing project?:D
 
Oh #### no! That's beyond my skills. This far has been bad enough. When you saw it, I had been gathering parts since Sept/04, it just now got chambered up and screwed on. In fact, I only screwed the barrel on tight this morning to test fire.
I just got a .50/460Wby reamer and a new Bevan King barrel, that is project number next.

My Gibbs takes 140 grains of 7828!!:rolleyes:

That will be a great looking rifle there Casull. Are you going to get the barrel turned down at all? 15 Lbs used to be a standard weight for a double in 577 so you can take a bit off a single!
 
I think so. That barrel actually has a threaded section on there too about an inch from the muzzle, there is a cap where a brake can go if desired. I am thinking I will make it lighter as I get more of a feel for what I want and can expect from it.
The 100 grain loads are only starters to test fire it. I have loads listing around 166 grains as standard. And this thing is far stronger than any of the old guns it was made in. I am sure top end loads with this would be staggering but I'm not I see any reason to go there, often at least. I'm sure it will kill plenty at both ends with soft factory duplication loads.
