45 colt ruger load info

[BigMagShooter]

the question.

I have a Ruger 45 Colt, I would like to load some of my 250gr cast bullets with. I have lots of MP-300 but cannot find any load data!

Ok I found ONE load data set. I like to compare a couple of load data sets to get an idea of how it goes.

does anyone else use MP-300? or H110 or W296 in their 45 colt ruger?

where did you get your starting data?

[DougGuy]

There is lots of data available for H110/W296 in the TC/Ruger Only sections of the load manuals. BUT..

That data is ONLY for the large framed Blackhawk, original Vaquero, Redhawk, and Super Blackhawk. It is NOT SAFE in a medium framed Ruger so if yours starts with a TWO digit prefix in the serial number, it is a large frame model and safe with the Ruger Only load.

If yours has a THREE digit prefix in the serial number, it is a medium framed Ruger and only safe with 45 ACP+P pressures of 23,000psi.

H110 and W296 are the same powder, made in the same plant, one is labeled for Winchester, the other is labeled for Hodgdon. The only differences in the two are variances from lot to lot. I do not thing mp300 is the same powder and it probably should not be loaded as if it is H110 or W296.

[C. Latch]

I do NOT think they are the same powder. Data calls for standard primers for mp-300. Everyone specs magnums for H110/W296.

here is what I found that gave me an idea they were all the same.

[BigMagShooter]

thanks for the heads up Douguy, but I know my Rugers. This will handle the Ruger only loads as that is why I got it. :)

douguy, maybe I'm blind, I'll look again, but the last 3 manuals I looked at for 45 colt ruger only loads didn't have any load data for H110, or W296. What book are you referring to ? I may have it and haven't looked at it yet or maybe I could find it on line.

[C. Latch]

here is what I found that gave me an idea they were all the same.

I'd have to hear it from someone at Alliant or Hodgdon to believe it.

[BigMagShooter]

so you only believe what you hear from the manufacturer?

ok, I believe you.

[C. Latch]

FWIW here's hodgdon's own load data for the .45. Includes H110/W296:

Nosler load data includes W296:

[str8wal]

here is what I found that gave me an idea they were all the same.

That says W296 and H110 are the same. The 300-MP is in a separate sentence.

The Hodgdon website has load data for Ruger +P loads using H110/W296.

[BigMagShooter]

thanks, I don't have a nosler reloading book and the website will be quite helpful!

thank you!

[C. Latch]

so you only believe what you hear from the manufacturer?

ok, I believe you.

I think the article meant that H110/W296 were the same powder, not 300-mp.

[BigMagShooter]

that article seems tricky to read doesn't it. I'm confused.

I'm still having a hard time finding any load data on mp-300 for a 45 colt. :(

[BigMagShooter]

sent Alliant an email asking about 45 colt loads for MP-300, I'll let you know what they say.

I'd be interested in that data myself. I was in a store yesterday and I think they had some on the shelf. I was looking for rifle powders and didn't pay much attention, but it seems like there was some there.

[BigMagShooter]

I scored an 8lb jug for cheap! so now I want to use it.

lots of good info for 357 mag loads... :)

Do as you please and what you feel safe with. I have seen a lot of powders pressed into use because it was cheap or that was all that can be found.
I bought some 4100, try and find any data for that to speak of.
Lot does take a LOT of time to put a manual together, but a lot less than years ago.

[Bzcraig]

I read that as saying 110/296 were THE powders to use for "top velocities" now the 300 MP must be added to give top velocity as well. It says nothing indicating load data is interchangeable.

[leftiye]

MP 300 (as is Lil Gun) is made with less flame inhibitors than H110/296. Will ignite more readily at lower pressures therefore. Where it really differs is in loads with very heavy boolits - it delivers more velocity because it has a slower pressure curve and doesn't go critical in those situations as readily as H110/296.

[54bore]

During a visit to the Olin powder factory years ago, I learned that W296 and H110 were the same powder. The information was later included in an article on handloading the .44 Magnum. I went on to say that any chamber pressure/velocity differences between the two are due to slight burn rate variations from one manufacturing lot to the next. That explained differing maximum charge weights published for the two powders in various reloading manuals for .44 Magnum loads.
That was back in the days when people wrote letters, and a reader took me to task for my statement. In an attempt to prove me wrong, he contacted Hodgdon and Winchester. Of course, representatives from both companies did not give him the answer he was searching for. They refused to comment simply because in those days they were competitors.
Now that both powders are under the Hodgdon umbrella, Reiber willingly confirms that W296 and H110 are indeed the same powder. If the guy who wrote that nasty letter about three decades ago is still capable of reading small print and has a copy of Hodgdon’s latest Annual Manual, he may see that listed charge weights, velocities and pressures for the two powders are identical.

I was under the impression from others on line that mp300 is the same as aa9 not 110

[BigMagShooter]

well, I await my response from Alliant. :)

thanks for the info guys.

[BCB]

I’ve used it with the RCBS 45-270-SAA. Twenty-two to 24 grains with velocities from 875 fps to 1148 fps. (Not sure where that data came from so be careful) I used CCI-300 primers. I did try CCI-350’s and the velocity went up 150 fps with the same powder change and the CC-300’s…

It works pretty well in the 357 Magnum with 358429’s…

I think H-110 is a better powder, but that’s just my opinion…

Good-luck…BCB

It is an animal all its own and behaves differently in the 357 and Max than AA9, 820, H110 and 296.

I agree with this...

QL does not list 300-MP, but I entered the same charge of AA#9 as I was shooting with 300-MP in the 45 Colt. QL gave a pressure of nearly 34000psi. I know I was not getting that type of pressure, or I don't think I was, as the cases literally dropped from the chambers in the cylinder...

Good-luck...BCB

[BigMagShooter]

ok here is my official response from Alliant..

Alliant has very little hard cast lead load data available. We normally refer to the Lyman Cast Bullet Handbook, 4th Edition for such load data. Looking to this handbook, there are two different configurations of 250 grain bullets. Neither of these list the use of Alliant Power Pro 300-MP propellant. This is considered to be magnum pistol propellant and the 45 Colt is not a magnum cartridge by its design. The Alliant propellants that Lyman lists in the above mentioned handbook are Red Dot, Green Dot and Unique.
The data in the above mentioned manual is copyrighted and you will need to either contact Lyman or purchase the manual.

Well, that's useless.

[BigMagShooter]

yep, I sort of guessed it would be since they only have ONE load recipe for a heavy wt in the 45 colt.

I see that. I still don't believe it. That sort of claim needs to be backed up. I'd almost call it irresponsible to print stuff like that, without documentation.

[BigMagShooter]

somebody else's turn to query Alliant on this.

[Bzcraig]

I am in this camp as well. What publication/periodical is that from?

[BCB]

357 Magnum with the 358429…
16.0 grains 300-MP = 1154 fps
15.0 grains H-110 = 1247 fps

45 Colt with RCBS 45-270-SAA
23 grains 300-MP = 1138 fps
23 grains H-110 = 1218 fps

From that data I acquired from several loads of 300-MP and H-110, it would seem that the 300-MP is slower than H-110…

I also note that the H-110 charges may be AT OR NEAR MAXIMUM so I don’t post this data to be used. It was O.K. (?) in the Rugers I have—but that all I’m saying…

Good-luck...BCB

[BCB]

Don't know how this is going to work, but I'll give it a try...

[BCB]

Let's try it this way!!!...

If it won't expand, the dang article is in Handloader #264, February 2010...

Good-luck...BCB

[C. Latch]

Don't know how this is going to work, but I'll give it a try...

Worked perfectly and that's useful data to me. Might have to pick some up now.

[BigMagShooter]

oh yea, good things are showing up. I too can use some of that data.

thanks!

I've been using 22 grains of h110 and a 300 grain Lazer cast bullet in my Ruger 45 colt for years. I haven't killed anything with it yet, but it's more accurate than I am. Don't quote me,but as I remember, the max load for that bullet is 24 grains of h110 so for my purposes 22 grains works just fine.

If you are going to post max load data on an open public forum, AT LEAST POST THE COA! COA is a CRITICAL dimension that with this much H110 could be disastrous if for instance the boolit has two crimp grooves, and load data is listed at the LONGER COA and someone just assumes it doesn't matter and seats the boolit in the deeper crimp groove, to give an example..

The article in post #29 appears to have been printed in the "guns and ammo" magazine.
