.45 colt rifle load data

Hey guys im trying to find load data for my rossi lever action rifle. I've noticed there load data for old replica revolvers and ruger and T/C ones. but what do i use for rifle? im using 700x and looking at doing roughly 7 grains. Any ideas?

I haven't started loading for mine yet... in fact, haven't got one yet... but need to by spring, if MRS is going to start shooting CAS with me next year, & I'm going to pass down my 38 / 357

I'm hoping to just use my revolver loads...

But I also have a load I hunt deer with, with a 10" Contender... don't remember the load off the top of my head, but it makes my trigger knuckle bleed by the 5th or 6th shot...

I'd look at the Contender load book, & pick one of the slower burn rate powders to optimize the performance out of the longer barrel of the rifle...

( unless you are also shooting 45 Colt in a revolver... in which case find a load that shoots well in both... may need to adjust your COL to work most smoothly in your rifle )

Reportedly the Rossi can use everything up to and including loads the five-round cylinder Ruger Blackhawks can use.

I've got an older Rossi 45colt. I believe they called it the trapper model.
It has a 16" bbl. & a big lever loop.
I shoot full power H110 loads out of it with no problem.
But I wouldn't recommend it for tender shoulders.
I also use 6.5gr. of titegroup behind 250gr. cast bullets.

RANGE REPORT:

I loaded a few rounds using 200gr berrys Hollow points and 7 grains 700x... holy crap... we were shooting a steel plate about 16 inches long and 10 wide. at 75-80 yards with some other rifles. I took out the rossi 45 colt lever action and was nailing it every time. there was little recoil and plenty of accuracy. impressed the guys i was shooting with. i have a new found faith in this rifle especially with this load.

there did seem to be some slight extra bulging in the case and will perhaps cut a grain of powder out to help case life.

Rbf, the 7 grain load of 700x is only about 15,000 psi, very light for a rifle, or even a handgun. I wouldn't change a thing if it's that accurate.

45colt rifle Data

With my Rossi Trapper 45 colt 16 inch barrel and my Rossi Ranch Hand with the 12 inch barrel my most accurate easy shooting clean loads are with 7.5 grains of Red Dot under a 250 gr rnfp bullet.
I can consistently hit a 12 inch diameter tree at 170 yards with the Trapper.
My hold over is just over a foot at that distance as I am sighted in less than 100 yards.
I tried IMR 4227 - 21 grains with same bullet and mag primer with similar results BUT the bore is a mess with kernels and slowly the action seems to pick up a few.
The Red Dot makes for a nice easy shooting load but I am looking for a powder that will give me a CLEAN burn in a mid level load.
Any advice in this regard greatly appreciated
Regards
Doc

Alliant's American Select is a little slower than Red Dot, much cleaner burning and bulkier as well, so it fills the case better.

I had considered American Select but had been told that Red Dot ,Promo, American Select, and Solo 1000 were so close their loading Data was interchangeable. Therefore their performance would also be similar.
I was hoping to find a Clean Burn powder that was in the mid range group giving more performance as well. Unique has probably the power level I desire but I am hearing that it too is leaving kernels.
If my guns were not lever actions this would not be as big an issue.

Try 7.0 gr 231/HP38. I shoot this in my lever actions and revolvers and it is very accurate with my cast 268 SWC bullets. HS6 is also good in 45 Colt for mid to higher level loads.

One of the hotter loads I shoot in my Bisley-Blackhawk is a 255 grain cast bullet with 12.2 grains of either Herco or WSF. (I wouldn't go over 12.5 grain cuz I like to keep the pressure well under 30 kpsi) Herco is a medium-coarse flake powder and WSF is tiny flattened balls like 231. Both give almost 1300 fps from a 7.5" revolver. In a rifle or carbine you'll pick up another 150 to 200 fps.

Thank-you all.

Is that WSF powder fairly clean burning?? I have not seen 45 colt load data for it. Looks to be around the unique burn rate

There is no data for WSF in rimmed cartridges, and I don't know why because it's a great powder. It's slower than Unique and seems to be interchangeable with Herco (according to my chronograph, in the few loads where I've tested it.)

Yes, it's reasonably clean.

Its this cleaning a lever from muzzle to breech that makes me antsy about the kernels that my 4227 load left. A little soot etc is no big deal.
I was just looking for a little more horsepower without trying to magnumize it or make it uncomfortable to shoot.
Thanks Again

I've been told power pistol is a good powder for what I am looking for. Has anyone used this is medium 45 colt loads and have any load data they colud share?

Many thanks

45 Colt Rifle loads

Slower burning powders don't burn well at lower pressures. If you are going to use 4227 or other slow burning powders, the pressure needs to be higher than is safe for the weaker guns. I like AA-9 with 300 grain bullets in my Marlin, but the pressure is necessarily high. I also like HS-7 and 255 grain bullets. With a rifle using faster burning powders the velocity gain over a revolver is perhaps 100 or so FPS. With the slowest burning powders you get the most gain, 300 FPS +or-. The middle-of-the-road powders will easily give you a 200 FPS gain and are easier to get good results with, without having to go into super-high pressures. Sometimes the best powders are discontinued by the manufacturer; like HS-7/W-571. If you find it at the gun-show, buy it before I find it.

I guess Power Pistol in 45 Colt with cast bullets isn't too popular??
Thought it may be.
Thanks anyway

It should work fine, I just haven't tried it yet. (For the past year, I've been practicing almost exclusively with .38 Special and actually avoiding my single actions.)

13.5 grains of PP with a 255 grain bullet should be a good +P (Ruger large frame, Contender, or Rifle, etc) load. Ballistic efficiency will be very good with a 20" barrel and you should get 100% burn.

If your happy with your load and powder performance, then just run a bore snake throught it after shooting and cleaning later should not be problem.

A little bulging is good in the Rossi. If you drop the charges much, the brass probably won't expand enough to seal the chamber and you'll get gas blowing by the case mouth and dirtying up your gun and brass.

Many thank zxcvbob for the power pistol load. I appreciate your reply. In your opinion would that 13.5 grains constitute a maximum load under a 255 gr cast bullet?? I kind of find it amazing that with the length of time this powder has been available , there is so little data.
Kind regards and again thank-you Sir.

I don't know, what kind of pressure do you want? (That's the problem with loading non-SAAMI cartridges.) Quickload says 13.5 grains will get you 25.8 kpsi, and about 1570 fps. 14.0 --> 28 kpsi, and 14.5 --> 30.2 kpsi. But the calculations may be off a bit. Also it depends on the seating depth.

I think 13.5 is a sane load.

I agree that 13.5 grains would be a sane load. I want to be under 30K for sure so 14.0 gr would be the maximum I'd ever go to.
I believe I'll start at 11.0 gr. and work up slowly watching my cases , accuracy and barrel leading for issues. I would be well satisfied with 1500 fps out of a 16 inch barrel. This would be my hunting round as your 7.5 grains of Red Dot which I use as my shooting round I am well satisfied with in all aspects.
Many thanks for your time and expertise in this regard and your fast responses.

My Speer manual lists a cast 255gr. Power Pistol load.
7.3gr. at 763fps. to 8.3gr. at 810fps.

200gr JHP at 8.6gr. at 829fps to 9.2gr. at 885fps.

260gr. JHP at 7.8gr. at 749fps. to 8.4gr. at 852fps.

Those are out of a 5" bbl.

I just got a Rossi M-92 in 45 colt. My initial loads were with W-571,(HS-7) under 255 lee cast, and 300 lee cast. Those loads were very accurate, no chrono data, but all bullets touching @ 25 yards. Bore was VERY dirty though. Unburned powder everywhere. Took some effort to clean it up. No leading.

As for power pistol, all I can find on the loaddata site is 9.0 maximum for 255 lead boolits to give 960 fps. No pressure estimates for that load. But they say all the loads were running 14,000 psi. The Rossi is capable of pressures just like the Winchesters and Marlins. So I too would be comfortable going up from there, maybe not to 13.5 though.

The loaddata site is a members only site to get the exact powder loads. You can go there as a non-member but the grains of powder is blanked out.

http://www.loaddata.com/home/index.cfm

For $29.95/year you get access to 229,550 loads in a searchable format. Also included is a loose leaf binder that allows you to keep printouts of the loads you searched for. All data can be printed in a printer friendly format to keep from using colors.

It's put on by the Wolfe publishing company, who bring us rifle and handloader magazines. A lot of the loads come right off the pages of the magazines. If this sounds like a commercial, then so be it, I only wish I had subscribed sooner.
