Has anyone put long range tang sights on Rolling block in 8x58R. Thinking??

[koger]

I have 2 Rollers in 8x58R, that are both great shooters out to 200 yds, as far as I can shoot accurately with the express type flip up rear sight. This is one of my favorite rounds, with the 245 gr GC Lee bullet. I am using a good dose of IMr 4198, with great results, I dont know why one of these rifles would not do well out to 5-600 yds with ease. I may have to get a decent sight and see how one does, drill and tap it myself. Any thoughts??

Why not I do with side locks ,Lee Shavers venire in my case (1250-1300 FPS) with TC Renegades/Ed

I have a Shaver tang sight on my 45-70 Roller and I love it. There's no reason not to if you're planning to shoot up to 600 yards. I'd say spend a little more and get a Hadley eye cup.

Not on this specific caliber, but on numerous military Rolling Block actions I converted to Sporting Rifles. I wouldn't ever build a Rolling Block without D&T for a 1.937" Remington tang sight base.

Thanks guys, I have Lee shavers with the Hadley cup on Cimaron down under 45/70 and a Remington roller Sporting rifle, love them. I just wondered if anyone had done any long range shooting with the 8x58r, and what to expect. Guess I will find out.

Not sure what for sure. But in general I'd not expect a lot of small groups once you get past 500 yds. Most .32 calibers aren't going to do well in the wind for the length of time it takes to reach 800-1000 yds.

It would be just fine at long distance.......if your can get a bullet that is long for caliber, problem is, not having the twist to support the length. I would try the 240gr's and see what happens. Or figure out your twist, build the longest bullet you can and push it pretty hard. You may be able to backbone off the 32-40 bullet designs as they are pretty close.

I have had great luck with the Lee, supposed to be 225 but is 245 with my alloy and shoots lights out. moI have shot it to 200 and bullet is stabilized. About 5-600 yds is the most I can shoot in my neighbors field, he and I both shoot over there a lot, he gives me free reign on his place. Just shooting for fun, steel plates of various sizes. I think the 245 gr for .32 cal is pretty heavy for size?

[bpcrshooter]

It really isnt about the weight, its about the length. If your twist cant support the length it will never be accurate at distance. I would find your twist rate out and plug that into a ballistic calculator and see what your max length is. Obviously running max isnt in your best interest, drop it .005- .010 or so off max for best results. Things really start to change once you get out past 300yd and the same past 800yd. whats good at 1-200yds might not be worth a nickel at 300. Only shooting it will tell you. Having access to 5-600yds is fantastic! loadem up and send them!

Most of the fairly old 8mm's were about a 1:16" twist, but I've never owned one in 8x58R, so couldn't even guess on it? If it is a 16" twist or slower, I think you'll have trouble with anything over 200 grs. when going very long distance with it. But depends on your idea of long distance?
In the old days long distance was 800-1000 yds., or more. Mid range was 500-650 yds.

[koger]

Well I guess I would be mid range then, dont have anywhere to shoot further than 600yd, until November and the crops are in, then I can push it out to 900+yds.

This was an 8X58 before conversion to 40-65. The sight was on it for the 8MM. It was a fine shooter both ways.

That is a looker my friend, thanks for sharing the pic.

[sharps4590]

I have an 8 X 58RD and did try the Lee 245 gr. (?) bullet. It made nice, sideways holes in the paper at 50 yards. To be fair, I wasn't driving the bullet as fast as I could so RPM's were down. It MIGHT stabilize in the roller if a high enough velocity can be achieved but, I'm not very confident. I gave the mold to a friend and remain happy with my Accurate 200 gr. bullet.

[koger]

I am running a pretty good load of IMR 4198, with no issues behind the Lee 245gr.

koger, what kind of accuracy are you getting with that bullet? I always thought if driven fast enough it should shoot quite well.

I used that bullet and 4759 and had quite good luck with it. Don't remember the load though.

I am getting up closer to 1900fps and sandbagged at 100 yds will shoot 5 into 2.5 inches, about what the front bead covers up.

[sharps4590]

Oh my!!! No wonder it shoots good for you! I was probably around 1200-1300 fps., certainly no more. You proved what I suspected.

I met this young man in Washington, the summer of 2015, terrific shooter. Take a look at this video with a roller and stare in wonder! I love that dinger sound! :)
