Hello everyone. I'm new to the forum. I just recently aquired a 1988 era TC contender pistol/rifle. I have a few barrels for it (223 rifle barrel, 10" 30-30 pistol barrel and a 10" 45 win mag barrel) the win mag is the reason im writing today. I am having a heck of a time finding reload data for the caliber. I ordered up 200 pieces starline brass and a set of carbide dies for the round. I also ordered some 300 grain jacketed projectiles for it (the smoke from lead rounds is something I tend to avoid if I can. I have the flowing powders on hand and was hoping to find a load that uses one of more of them : winchester wst, h110 and power pistol. I have found a total of 1 load using h110 (18-20 grains with a OAL of 1.485") and will be trying a few in this range as soon as my cci 350 promers arrive. Assuming that thisload works well I'll be loading up more. But if it doesn't shoot well I'd like to have a few more options, especially if it includes a powder that I ready have on hand. I'm not planning on hunting with this gun (at least not untill I become MUCH more comfortable with it), but I'd like to develope an accurate target round for it. Anyone else here load for 45 win mag in 300 grain? I'd really appreciate any advice you may have. Thanks ahead of time for any in info you can share.

that's one .45 I haven't loaded, have .45acp, .45 Colt, 45-70.
reason would dictate that the longer barrel should make good use of slower burn rate powders it seems.

Welcome to the Forum. I checked a few of my reloading manuals for data. You did not mention what brand of bullets you ordered. Specific manufacturers data for a certain weight bullet will NOT be 100% interchangeable with other makers bullets.

I'll tell you a story in regard to my experience with this. The max charge for a Sierra .44 Mag 300 grain bullet is 19 grains of 2400 while the Hornady 300 grain XTP is 17 grains. Years, years ago I assumed all weight bullets used the same data and only had a Sierra manual. I had worked up the Sierra load and shot hundreds of them. Couldn't get any Sierra's right before hunting season and substituted the 300 Hornady. With no time for properly working up a load I loaded a few for hunting season and headed to the North woods. Test firing up North produced very sticky ejection and flattened primers. Promptly purchased some Factory Remington for the hunt. After hunting season I purchased a Hornady manual and was horrified to learn their max was 17 grains instead of 19. Loaded a FULL 2 grains over max. Luckily I was shooting a Super Redhawk or I may have had a blown up gun, or worse. LESSON LEARNED. Just try to get the manufacturers data if possible. All right enough preaching now to the data.

The older Nosler #3 has data but the newer #7 does not. They only list a 250 grain bullet with the following powders. HS6, Blue Dot, HS7, 2400, H110 and H4227.

The Hornady 8th lists data including the 300 Grain XTP. (I'll wager a guess that is what you ordered). Their listed powders include the following for the 300. 2400, A No. 9, Win 296, H110 and IMR4227.

W296 and H110 usually work best at full house loads. They will give you the best velocity but have a small range of load weight. If you wanted to shoot anything from target mid range to full house loads the 2400 is probably your best bet. I've found the 4227 powders are quite dirty at reduced levels.

Let us know what bullets you have coming and I'll see if I can get you a little more specific data.

Don't want to muddy the waters but some manuals also list a T/C specific load that is at times higher and at times lower than their revolver data. If you had an Encore you would have a safety margin with the Contender being a bit weaker. Work up a load carefully and keep us filled in.

Glad to hear about a new T/C fan. We are a shrinking breed.

Thank you guys for the replies. I see that I did in fact forget to list the brand. I will be using Sierra sports master bullets. They are .451 dia. jacketed soft points. I am considering ordering some 250 grain projectiles as well. I have a couple loads that use them that I could try. I'd just like to get my hands on all the reputable load data for this cartridge that I can find and then I can order components accordingly. Thanks again.

The Sierra Edition V Seventh printing has the 45 Winchester Magnum Data in their revolver section. That manual also has a huge single shot pistol section but does not list the 45 Win Mag in it.:(

For the #8830 .4515 300 grain JSP it lists a COL of 1.550.

Nine powders are listed. Many as mentioned before but they also had Unique listed which is good for reduced range loads. Powders listed are as follows:

Unique, Viht 3N37, AA-No 7, HS-7, Blue Dot, AA-No 9, 2400, H110, and W296.

The accuracy load was listed as 16.3 grns of AA-No 9 1000 fps.
The hunting load was listed as 11.2 grns of Viht 3N37 1050 fps.

Per the manual the load for the H110 that you have on hand is:
start 15.0 @ 800 fps................. max 19.0 @ 1050...........used with a Fed 155 Magnum primer.

As I mentioned above I shot the .44 cal Sierra 300 grain JSP by the box full. An excellent bullet. I'm sure the #8830 will be just as good.

Hope this helps.

Thanks a lot. I'm expecting my primers in the mail this afternoon. I'll load up a few on the low end and take them out to see how they do. I'll keep everyone updated. Thanks again.

10-4 on the data. As I mentioned above the H110 excels near the max load area. I'll wager a reduced load near the starting data probably won't give stellar results. If you can find some 2400 it should be superior at the low and midrange loadings. If you do drop me a PM and I'll get the data to you.

Keep us filled in.

Thanks for the offer. I contacted the gun store I usually go to for powder and there out but have some on order due to arrive next week. He is going to hold a pound for me.

Got your PM in regard to getting some 2400. Per the same Sierra Manual for the same bullet #8830, only change is substituting 2400 powder, the data is as follows.

Once again... COAL at 1.550.

Starting load at 13.4 grs @800 fps

Midrange loads at 14.7 grs @900 fps............15.3 grs @950 fps

Max load at 16.7 grs @ 1050 fps


Data noted that the Fed 155 magnum primer was also used for the 2400. Not required as with the H110. Good thing is the data was developed with the magnum primer so if you use a standard primer your pressure will be a tad less rather than vice versa. I've used the magnum Fed 155 extensively with 2400 with no issues. As always work up your loads checking for signs of pressure.

Keep us filled in.

Well I took the Contender out for the first time this afternoon after loading up some 300 grain rounds in 45 win mag to Bepe's recomendation. With an OAL of 1.55" and a load of 15.5 grains of 2400 powder I found the gun quite enjoyable to shoot. Thanks for sharing information on a load that is a little difficult finding load data for.

How was the accuracy? I was thinking if I were loading it I would start just about where you did.

I didn't have a proper bench, but shooting off a bag on the bed of my buddies truck i managed some respectable groups (for me, a non pistol shooter) 1.5" at about 50-60 yards (2.5-4 x scope). I'm quite happy with it myself. I'm sure many people here would laugh at my "accuracy" but I'm a rifle guy and pistols aren't really my thing. This gun may actually change that though. This thing is a blast to shoot.

My Grizzly prefers lighter bullets. 2400 has been the most accurate, followed by H4227. 296/H110 has been "alright."
