Here it is. I just bought it! My first REAL BIG BORE Rifle! The rifle is a Ruger M77 MkII Magnum in 500 Jeffery. It was rebored by somebody, and it is COOL!!!

I took it shooting yesterday! Does this this rock!

Here is a picture of me and the new rifle.

Great AC
post some more pictures
Congratulations on your .500 Jeffery if you want so help with the reloading I know this great guy
Do I se John Daniels on the floor

Cheers,

Andr�

Yea, after a bottle of Jack Daniels even a daisy would Rock.


Congrats on the new rifle. Two big bores in a couple of months is just the right purchasing pace for a real big-bore looney. Keep us informed on the progress.

Scott,
the scope is just weird on a 500 jeffery!!!

i think it's a touch too long for you, but that might just be the angle

congrats.. that's a real bigbore

jeffe

There is no picture coming up for me.

I don't know if it is too long or not, but it sure did NOT bruise my shoulder like the other rifles have. The LOP is 14.5", by the way. Of course a little JD does help with the post shooting shoulder soreness.

The scope came with the rifle, and I actually like it ALOT! I think left of 3X it is about perfect.

Scott, are you drinking that J. Daniels or rubbing it on your shoulder?



I hope you don't get to playing around with this gun and accidentally touch one off in the house. You'll think sore shoulder when your ear drums pop out of your head.



I'm still waiting to see some results on the 45/100. Frankly, that gun interests me more than this one.



Be safe and enjoy. P45

jeffe, I don't think it's too long for him. He just needs more experience holding a rifle so that he will hold it properly, instead of leaning away from it.

To ease the pain of a sore shoulder, your drink the bottle of whiskey and rub where it hurts with empty bottle.

Wow! She's a beauty AC! That's definitely "enough gun" for anything you could ever encounter.

The Ruger M77/MkII RSM is a fantastic rifle for a production gun - it's topnotch in quality and probably the strongest bolt gun made as Ruger's all tend to be. I just got one in .375 H&H and absolutely love it.

Enjoy it and keep us up on your range adventures.

458RugerNo1,



Yes she is!



Pecos, I traded the Pedersoli Sharps in for this rifle, plus a few $$$.



Just back from shooting and made it through 10 rounds with only moderate stiffness. It is DEFINITELY more shooter friendly than the Sharps or the Beowulf were/are.



Shot a 2" group at 50 yards!!



I tried a load of 103 grains of IMR4064 and a 570 grain Barnes "X" bullet, kicked plenty hard, but was accurate. Chronographed avg of the 10 shots was 2217 fps. Anyone got any pet loads they would like to share? The bolt was a little sticky on these loads too, software thinks the loads are around 49,000 psi, so I did not think they would be a problem pressurewise, although now it appears that I was wrong (or the software is WAY off, it was close on the velocity though as it predicted 2231 fps). Brass is Bertram, I think, I was told that it was and it has a kangaroo and "500 Jeffery" on it for a head stamp. The rifle came with 20 pieces of brass and dies.

Congrats AC. That thing is bigger than anything I have. I'll have to see what I can do about that.

I went out to Pontiac Lake Shooting Range this morning (Saturday, June 12th) and found it closed for construction until near the end of June. Also was told the backstop wall collapsed several days ago due to the heavy rains.

No one has any pet loads???

ASS_CLOWN

Scott,
I don't use that bullet, I jsut use, mostly, 535s from woodleigh or hawk, andor hard cast GCed... and either rl15 or wc852... those cases are HUNGREY for powder, and will burn ~45 cents a shot on commerical powder

jeffe

jeffeosso, would you be interested in sharing your loads?

ASS_CLOWN

What? Say it isn't so, AC wouldn't tell a fib to us, and neither would his feminine persona Judy.
Maybe that's why he only got 10 shots at the 50yd line in, the 50 was the only thing standing and the fish cops threw him out as soon as they could get through the mud.
It's been 15 years since I used that range, but the layout is probably still the same.

Ass-clown that load of IMR4064 doesn't fill the case very well. You'll need to add dacron filler for more uniform ignition/velocities. Try 129-132 grs of IMR4831 with the 570 gr woodleigh. I use that load in my 500AHR and there isn't much difference between it and a 500 Jefferey. These loads will run about 40Kpsi and are in the 2250fps range. You get about 98% case capacity with that load. Accuracy is as good as you can shoot at 50 yrds. I shoot this load with a scope and it's no problem.-Rob

Robgunbuilder,

I just happen to have some IMR4831, as I use it in my 30-06. I will try some of your loads this coming weekend, or sooner if I can get out to shoot.

Would you think that 128 grains with the 570 grain bullet to be a safe starting point?

By the way, have you ever experienced hard extractions with your rifle? My bolt turns okay for 45 degrees or so, and then gets hard when the extraction cam is engages, ie the extractor claw has finally came in contact with the rim and the extraction cam is actually doing something .

I am thinking this must be brass related as my loads should be no more than upper 40s ksi.

By the way, there isn't that much empty space in those 103 grain loads. The Barnes bullets is long, with ~ 0.65" from the base to the middle of the cannelure where I am seating them. I figure the load is ~ 93% load density.

ASS_CLOWN

Scott, how does that Ruger feed? As you know, 500Jeffs can be tough to feed properly. Do you know if the rails & ramp were modified? Do you have any idea who rebored it?

Bertram brass as you know is notorious for being too soft. This also seems to be very lot dependent. I believe Huntingtons may have some Horneber .500 Jeffery which is infinately better stuff. My AHR brass comes from Bertram via AHR and I've had no sticking problems with the load I provided. Since the Jeffery has a whole bunch of chamber versions, I'd probably make a cerrosafe chamber cast and make very sure your brass is trimmed .010 short. I've only shopt woodleigh sp and have no experience with Barnes bullets although I would imagine they would lead to higher pressures than woodleighs due to the increased bearing surface..-Rob

Hey, just because everything Scott ever said in the past was a lie does not mean that what he is posting here is not the absolute truth.

Robgunbuilder,

Learned something tonight. I cannot get more than ~ 129 grains of H4831, IMR4831, or IMR7828 into my 500 Jeffery cases. Therefore, I will load to the max and see what I get. Based upon your data I am expecting to get ~ 2250 fps (probably 2200 fps with the IMR7828) and hopefully no sticky case extractions.

Flinching is a nervous response, so the Jack Daniels is applied before shooting, to calm the nerves before squeezing off a big bore. Makes sense to me. I like to shoot a Ruger in .416 Rigby, every time I carry it I think it's too heavy, every time I shoot it I wouldn't want it a bit lighter.
