Rossi 45 Colt Carbine

[Barman54]

WELL,
I picked up a Gently used Rossi .45 Colt Carbine that was on Consignment at a Local Gun Store.
I have a Ruger Bisley, and a Smith 25 in .45 Colt for years, always wanted a Rifled version.

Will have to see how my Pistol reloads shoot in it, 8.0 Unique under a 255 Hard Cast?
Hopefully next Wkend?

Please post your results. I got consistent 14” groups at 50 yards with mine using any safe Unique charge listed.

I Hope mine does better than 14" Groups, Guess that is 3 Minute of Deer?
No Harm intended,

In mine I use soft lead cast, plainbased bullets of .454-.455 diameter which I use in my Colt New Service and Pietta SAA clones, as well as in the Rossi and H&R Handi Rifle. A charge of 7 grains of Bullseye with Accurate 45-264H feeds well and is accurate. I cast bullets from backstop scrap, lube with 45-45-10 and load as-cast and unsized. Kills deer too. Large meplat shoots through critters from any angle. Hollowpoints not needed.

Grouping is 2 inches at 50 yards from benched rifle or same at 25 yards from sandbagged revolver. Velocity 880 fps 5-1/2" revolver, 1080 fps in 20- inch rifle. 1000 rounds per pound of powder has nice ring to it. I use no other load in .45 Colt.

I have a newer Rossi 92 in 45 Colt. My standard load of 9 gr of Unique under a 250 gr bullet will group very well at 50 yards but open up a lot at 100 yards.

I have settled on a load of 20 gr of IMR 4227. This runs just over 1300 fps at the muzzle and groups 3-4" consistently at 100 yards.

[FergusonTO35]

That 4227 stuff is over 50 bux a pound here.

[Kosh75287]

That 20.0/4227/250 gr. load is a goody. I forgot what it chronographed at, from my carbine, but I would believe 1300 f/s. I use 4227 when I cannot obtain 2400, which appears to be on its way to being a fact of life.

I had a circa 1986 20" and a 2013 16" both had huge chambers and .450 grooves . It worked out the necks were small .....they were big enough to feed the .454 that works in the Ruger BlackHawk.

After a very embarrassing check in where at sight check I threw the hunting loads around much like the above 14" at 50yd , after a week of drilling 60-75 yd plates with mild plinker loads . I went back an killed hogs 127-165# on the hoof with the light loads .

Getting back home from the 400' msl Texas hog hunt and 675' elev Rondy thing in Missouri , I went to a shoot in Winemucca NV at about 6000' . I had the hunting loads that did 1050 fps in the 7.5" Ruger BlackHawk and 1240 out of the 16" . I shot 3x 86 25 yd 5 from the BH 5 from the rifle 6" ring companion contest and scared the skins off golf balls all the way to 70 yd someplace between 78&82 yd everything just fell apart. At 115 yd it was slinging bullets into about a 4' circle just about 6' high and 10' left . Doing what any male would do I held under and right working the hits back to the target I finally got back to a golf as a point of reference next to a 75 yd stand post and hit it ........

Now all of the above was repeated at home at 4100' on the west side of Walker lake NV . I did it over and over with the Lee 452-252 @262 gr , 452-255 @265 gr , a Lyman 454424 @ 257 gr , and an NOE 454-250 Kieth that is basically a 250 gr 454424 , and a 45-200 RCBS. I'd been playing with the Strelok app for rifles to get the legal big game load of 1000ftlb at 100 yd and decided to plug in the 45 Colts numbers with Chrony numbers ........
The Keith Types and RNFP were hitting 1100 fps at 76-81 yds . That big fat Lee SWC when plugged with atmospheric conditions for Texas dropped to 1100 fps at 47 yd . I have to draw the conclusion that the 1-32" twist just isn't enough gyroscopic stability to get through the transonic back to subsonic.

This isn't some 10 round "well that didn't work" one weekend thing I shot 100s of the Lee and NOE bullets and probably over 200 of the Lyman bullets the 45-200 lasted about 1 box being not a good choice in the tube mag .
My final conclusion is that you have to keep whatever you shoot in them up to 300 gr below 1100 fps MV, 1050 is even better if you want to consistently hit anything at 100 yd or you need to have them rebarreled with a 16" twist .

For the record I worked up to a 350 gr RN custom from Mountain Mold a 453-350 after the above working with fast rifle powders I thought I was pretty clever . The Lee 458-340 sized down made round holes so a 350 shouldn't be that much different........wrong . I did drive it 1240 with a digitally generated start load of 19.0 h322 that should have been about 18 kpsi just not enough twist . That also convinced me to just go ahead and buy the 45-70 .

The 20" produced the same results.

I just use mine for plinking. It seems to like about load I put in it. I hope you enjoy yours.

The Big Loop 16" carbine I once had worked great on whitetail, using Cor-Bon +P j-word 200gr slugs.

I use mine for target practice and patrolling for 'yotes with the Lee 125. So far it works great for that purpose. We can use any center fire we like for deer so I don't have to hot rod it.

[Griff]

I feed six 45 Colt rifles, 5 of which are lever guns and one 1885 low wall. The only loads I hotrod are for my Rossi with J-words. Depending on use, I shoot from 160 grain to 225 grain. It's been so long since I've shot any of them over 50 yards, I couldn't tell how accurate any of them are beyond that distance. They're all "minute-of-deer" inside that tho'!
Here's a comparison of them all using the same load:

And the targets... don't ask which is which!

[farmbif]

I only shoot one bullet out of my Rossi 45 colt and have settled on one load the combination works great, the mp454640-255-275 grains depending on hollow point pin used, lube sized to .454 and they all get the same load with 20 grains 4227 and have been using winchester primers. velocity is right around 1200fps

[Walks]

I got one when they first came out in mid-90's. So did 2 of My friends and fellow Cowboy Shooters. Out of the 3 rifles 1 had to be worked on several times to feed & eject properly ( not mine). My friends both used 200gr RF over 6grs of Clay's. I used a 230 TC over 5grs of Clay's.
My favorite plinking load is #454190/#454424 over 8grs Unique. It's an accurate load out to 50yrds. About 2+ inches from the bench. Never tried beyond 50yrds.

[missionary5155]

We have several Rossi's and at least one 45 Colt. The 255 RNFP Lee works well enough to head or shoulder shoot Ground Hogs at 50 yards if pushed fast with Unique.
I am 4500 miles south of the info. But I do know they are as fat as will chamber.

[hornetguy]

I give up. I've tried 3 times to post a reply, with target pics, and the reply just locks up and "grays out" every time.
Briefly, I've had great results with AA#5 for 1100-1200fps loads.
2-3" groups at 50 yards.

[hornetguy]

Try again... upper pic is the one of the 255 gr, 10 rounds. Lower pic is the 235 gr, 5 rounds

Well,
Made it to the Range Yesterday
50 Yds 255 Hardcast 2 Loads 8.0 Unique, 7.0 WSL (Win Super Lite), had loaded four years, still have 1/2 a Pound left.

Rifle has a Kick to it.
Shoots about 8-9 inches left, if I favor it got the centered up on the MR31C target @ 50 Yards.
Tried to Drift the rear sight, had the Punches, but not a Big enough Hammer at the Range.

3 of the 5 shots fired were in the Black, other two were in the White but on Paper, again while Favoring.
5 3/4 In Black Circle, no bigger than 3" spread, two were 1 1/2, with Unique

Chrono'd Both 8.0 Unique, 1306 Avg., 7.0 WSL 1070 fps

Will try to Post Pics, have to use a Different Computer, this one has S Secure on it, very restrictive on what it can Upload/download, QVC Purchase.

Overall Not too bad.

Oh, I single loaded each from the Top, just wanted to see how it shot, will try Loading and Moved sights next Time.
