Lyman Globe/Skinner on the Carbine Barrel?

[ESquared]

Hi, all,
Am stalking a Brass Carbine-length 45Colt, on which I'd likely put the Skinner Express rear sight.

I really like the Lyman Globe front, but can't figure out what height is needed for the shorter barrel on the carbine.

Any insights on this (so to speak)?

AHB = .404"
AMI = .494"
AUG = .584"

TractorTad seems like the expert on this...

We have a BBB44Mag carbine with a Skinner Express rear and a .494" Lyman Globe on the front - this setup is probably the best guess/starting point for a 45Colt...

remarkable .... to ask such a technical question and get an immediate answer .... yep, to me that's remarkable ..

I wouldn't call that the starting point, Tad, I'd call the THE ANSWER! Thank you so much, as always!

Remarkable, to be sure! One of the things that makes this forum so great!

Do you think this setup would work on a BBS carbine in 357 as well?

[ESquared]

The only difference I can think of is the octagonal vs. round barrel, but I'll let Tad render his expert opinion!

I also have the same .494 on the front of my .41Mag and so far it's working great for 50 yards

The answer to that is probably not - We have a BBSCCH 357Mag Carbine with this same setup (Skinner Express/.494" Lyman Globe) and it shoots 2" high at 25 yds using 158g JSP Federal ammo. This is with the rear Skinner peep bottomed out as far down as it can go. A BBSCCH Carbine has an octagon barrel that is slightly thicker at the muzzle than a steel round barrel, so the .494" Lyman Globe would sit a little lower on that round steel barrel - which means this setup on a BBS 357 Carbine would probably shoot even higher than ours with the rear Skinner peep bottomed out. If it were mine, I'd go with the next highest Lyman Globe (.584") with a Skinner Express on the rear.

Another option is to mount a Skinner Low-Pro on the rear/.404"Lyman Globe on the front. We have BBS 44Mag Carbine with this setup and it works well. I would estimate that this setup would probably work on a 357Mag BBS as well. I think we will probably end up putting this setup on our CCH Carbine in the near future...

Thanks! I haven’t decided if I’m going with the globe or just a taller blade from Skinner to go with the Skinner Express.

[ESquared]

I can vouch for the LowPro. Very simple to install and adjust. Completely different 'look' than the Express, so that boils down to personal preference and/or cost. I went with the LoPro as it was my first Skinner and just wanted to make sure it worked for me (and it did). My next will probably be the Express.

[Rifletom]

This is all very good to read. As I'll be getting my Henry .45 with the 20" round barrel, improved sights are being considered.
The LoPro and the Lyman .404" front would seem to work. If another is suggested, I'm all eyes. Excellent thread.

[ESquared]

For what it's worth, here's a pic of my BBS with the brass LoPro and the Lyman Globe, along with a fine-pointed Shaver insert (which is another variable we haven't covered yet). The Shaver inserts are much more finely detailed and you get about 10 to the card, as I recall. The target is not very distant (only 100 feet), but I was brand new at all this back in July. That set-up should work well for you. Keep us posted and thanks again to TractorTad on behalf of Tom and me - appreciate the wisdom!

[Rifletom]

Evan, that looks good, darn good. Agreed, tractortad knows the iron sight set-up well. The wood on his .44 is really something. Those Shaver inserts just fit right in the Lyman Globe, easy-peasy? Liking those.

Tom,
Yes, the Shaver inserts are machined for the Lyman globes. No difference in terms of fit. Here's a link:

And, YES, Tad's .44 is a beautiful specimen. I remember seeing it for the first time when I was new here and going "WOW!", but seeing it again in this thread triggers (so to speak) the same reaction. Great looking gun and just a great photo!

Can you adjust for windage with the LoPro?

No, it's just a threaded stake in the receiver. No windage adjustment.

Wanted to follow up on this thread, as I took Tad's advice, ordered the .494" front sight and set out for the range today with 250 gr Missouri Bullet's "Hy-Tek" coated projectiles and 8.0 and 9.0 grain loads of Unique, just to see how it sighted in. I used the Shaver insert pictured.

I started at 25 yds, moved to 50, back to 30 yds, switched loads, and all I could get was the darn thing printing high. This is the last target, 10 rounds w/ 9.0 gr of Unique. As noted, these were all @ 30 yds, and, except for the first two rounds, which appear at the top of the target, these are all basically at a 6:00 hold.

The Skinner rear sight is as low as it will go - it bottoms out against its receiver, so that's not an option.

I guess the basic question is: Is this okay for such short distances with this rifle/ammo? I guess my goal would be to be dead-on at 100 yds, but I can't see that bullet dropping that far between 30 and 100 yds out. But, this is my first experience with this caliber.

I could always try a different insert (which is on tomorrow's to-do list with PT7 at a nearby outdoor range) and get to 100 yds to see what happens, but my fear is that I'm just going to need a taller front sight.

Thoughts? Advice?

[ESquared]

According to this online ballistics calculator, that bullet is rising by about 3" at 50 yds, so I may not be all that far off. The site didn't have Missouri Bullets, so I just input Winchester 250 gr Lead Flat Nose, at initial muzzle velocity of 1,150 fps, which is likely very close.

[ESquared]

Sorry, folks, maybe I should have done some research before posting, but I've found another ballistics sight that indicates similar data for a 250 gr 45 Colt bullet, i.e.- it's at about +4.5" at 50 yds, so maybe I'm not all that far off...

Would still like your input, though. I'm new at this..

[Rifletom]

Evan, I got your PM and looked at the target. I'm not sure as to a answer yet. I still need to get to the range again and see if I want to change sights. I'm not much help right, sorry. But, I know we'll have this dialed in pretty soon. Raining steadily right now, so, into the garage for some loading.
