Rossi Rifleman

Hello Gentlemen,
Wasn't sure whether to post this here or in the reloading section so here goes. Apologies if it's in the wrong place.
A friend of mine has an octagonal barrelled 45 Rossi and would like to load some slightly warmer rounds. I believe the action is strong enough but thought I'd best check with you all first?
He's currently using N340 with 250 grain bullets.



Cheers

as long as the handloads do not exceed credible, published Max data, the 92 can handle it. Exceeding published Max data can get you in trouble with any firearm.

Make smoke,

Thanks Gentlemen,
He's a good friend so I've ordered the Lyman Cast Bullet Handbook so he doesn't blow himself up!
Having spoken to him at the range today I suspect he doesn't want to hot rod the loads just achieve around 1200 fps. I suspect he'll be able to achieve that with the right powder.

Good evening
We have 3 Rossi (older Interarms imports) in 45 Colt. 1200 fps is not hard with any cast bullet. Actually you can get there with 3F black powder with a 200 grainer.
Unique, 2400 and most any powder with similar burn rates should do it. Most any reloading manual will have 45 Colt carbine loads. 1200 fps will be starting loads pretty much.

I posted this here last October after picking up a new R92 in 45 Colt. Hope it is of some help.

I chronographed a few 45 Colt loads from the 20” Rossi 92 today. I had 2-5 of each and only wanted baseline velocity so you won't see standard deviation, extreme spread etc. this time.

As always... these loads have proven safe in MY guns. They were worked up carefully, some over a period of years. I recommend you consult reputable reloading manuals, begin with the 'start' loads and never exceed their listed maximum. I assume no responsibility for anyone duplicating my loads.



Left to right-

1. My bulk 45 Colt Maplewood Bullets Lee 452-255-RF over 8.5 grains of Universal and does 910 fps from a 4 5/8” New Vaquero. This load does 1180 fps from the 20” Rossi. It's also the only load tested here that is safe in the New Vaquero and is a pussycat from the carbine.

Everything below is for heavy frame Rugers, Contenders and modern-made lever actions like the Winchester 92 & 94 clones and the 94 Marlins. Do not use them in Colt sized sixguns or toggle-link rifles like 1860 Henry or 1866 or 1873 Winchester clones.

2. A 255 grain Missouri Bullet SWC over 13.0 grains of HS6, always good for 1050-1075 fps from 4/58 to 5 ½ inch Rugers and 1232 fps from my previous 16” Rossi carbine. It did 1351 fps from the 20” Rossi.

3. A Sierra 240 grain JHP over 27.4 grains of H110 is a deer killin' machine at 1257 fps from a 5 1/2” Blackhawk. My previous 16” Rossi carbine produced 1550 fps with this load. It did 1699 fps from the 20” Rossi.

4. A 300 grain, .452" Hornady Mag XTPs; old production with a single cannelure over 22.0 grains of W296 powder. It runs 1093 fps from a 4 5/8” Vaquero and produced 1485 fps from the 20” Rossi.

5. The RCBS #82083 is listed as a 300 grain SWC with a gas check base; the alloy mine were cast from drops them at 315 grains, +/- a grain, for the finished bullet. I load it over 22.5 grains of W296 which scoots them to 1558 fps from the 20” Rossi. Not far behind standard loadings of the 45-70 and I doubt game under 1000 pounds could tell the difference.

Footnote- This rifle fed all these loads in a mixed magazine, no glitches or complaints.

My kinda post, those are looking good. Cant wait to get and start reloading for 45

Thanks for all your input Gentlemen.

The Lyman cast manual turned up today and is currently being read by my friend. He's happy and hopefully a bit safer.......

Cheers

I went ahead and moved the thread while it didn't hurt anyone in the 92 thread It is better for future use in the hand loading section. All is well Namaste
