RG .45-70 crown, and sights.

You can read my full saga of trying to get a working 45-70 in the Rossi Customer Service Experiences section. I think for now I'm done needing their services, but minor gunsmithing remains. I reported the newest gun has a totally slick action -- feeds & cycles like a dream. I also noted the barrel had no crown/chamfer. Took her to the range with a box of vintage WW 405 grain slugs in balloon head cases, and a box of Hornady LEVERevolution. Windage was perfect from the factory, but elevation is the problem. the 405 slugs were between 4 and 5" high at 25, 50, and 100 yards, while the LEVERevolution slugs were 12" high at 50, and 22" high at 100 yards -- this with the rear sight all the way down. To conserve ammo I was only shooting 2-shot groups, and they were always side by side. So I dropped the gun off at my smith -- $21.00 and he'll cut a new crown. I'll then re-evaluate the elevation issue, and we'll install new sights. At this point I don't know if just a taller Marbles on the front is what I want, or if I'll go with Skinner sights. I'll have to search the posts on this site for you guy's recommendations. I'm open to any and all suggestions!

So I got the re-crowned gun back today -- the ham-handed helper at the gunsmith dented the magazine tube. I can't freaking win! Smith says he's got a swage to straighten it. So this weekend I'll check elevations, and will select a new front sight -- I like a small brass bead about half the size of the Rossi factory sight.

Gun still shooting real high with the new crown. Just dropped it back off with my smith. I'm having him install a Marbles semi-buckhorn identical to the one I have on my Rossi 92 .44 mag. A 1/16" Marbles gold bead will go on the front. With info from the targets he'll do the math to get the right heights. He was pretty embarrassed about his helper denting the magazine tube ... that'll be a N/C repair!

Finally got the Marbles sights installed. I like the target picture with the 1/16" brass bead. I hope to check zero this weekend. I'm going to name this gun "Pig's Ear" as I'm trying to make her into a silk purse.

So, off to to the range today -- first time with the Marbles sights. Target at 50 yards, two shots with my 300 gr lead load at ~ 1500 fps, shots almost touching, 1" off center at 4:00. Fired some W-W 300 gr HP's, about 2" high at 50, about 1" low at 100. I think my smith nailed the front sight height. Action is fairly slick, trigger is nice. It took 7 months, but I now have the gun I wanted. I'm finally quite pleased. Stock will get some Danish oil, and I'm sure I'll need longer screws for the butt pad. Now to read Ranch Dog's post on hand loads...

Sounds like it is going to work!

When I read the first post. I thought front sight too short. The last thing I would suspect is a bad crown if it is shooting consistently high or low, right or left.
