So I read alot here on the forum but, don't post much. I do however have a question. Is anyone running different loads for different distances. I do some silhouette shooting at three different distances and would like to hold on target for each. Currently I hold high or low depending on the distance. Thanks for any help.

Welcome to the forum from KC! There are lots of 45 Colt reloaders here (I'm just getting started with it), but I imagine they'll want to know what I'm curious about, such as "What 3 distances?" and "What projectile are you using?"

If the distances are hugely different, I don't know that you can fight the physics of bullet drop, but lay out what you're dealing with and that'll help.

Welcome again!

Good point Esquared. I'm shooting 50, 75, and 100 meters. Running a 250 grn rnfp. I have been using hp-38 and Unique.

Posted: **Tue Feb 26, 2019 8:42 pm**

Greetings Mzzlldrinpa, others will chime in, but, I'll give it a whirl. 50 and 75 meters, I'd stick with 8.0-8.5gr Unique with those 250gr RNFP[lead] bullets.I'm thinking for 100 meters, 8.5gr Unique should do. If you switch to jacketed, perhaps 2400 would work better. As I'm getting started loading the .45 Colt myself, thats the direction I've gone. mostly the Missouri plain RNFP, 250gr. Those work well. Hope this helps a bit.

I've been shooting Hornady 250 grain XTP's (jacketed) with 20 grains of 2400, I really like this load for my Henry rifle and Super Redhawk Alaskan and it's a pretty flat shooter. This is a high pressure load though and should only be used in appropriate firearms. Good Luck!!

Welcome from France !

I'm witouh Tom (above). I've focused on Unique for my 45 Colt, and I'd think that if you got an acceptable "zero", sight-wise, at 75m with 8.5 gr of Unique, you'd be within an MOA at 50 and 100m. I'm assuming you're talking about iron sights?

Surely that would get the job done on silly-wets (as someone around here calls them), wouldn't you think? Worth giving it the ol' college try, that's for sure!

Welcome from Va.!
Your .45 Colt load will depend on what type gun you are going to use.
If a rifle like a Henry or Marlin you can load it up a bit to Ruger/Marlin loads and using a jacketed bullet get more speed for a bit flatter travel.
However using the earlier design Winchester 1873 rifle with toggle link action you should stick with the 14000 psi Colt loads.
For revolvers it's much the same with the beefy Ruger Super Blackhawk and Redhawks handling the heavier Ruger only loads and the
standard Colt loads for the Colt type revolvers.
I only shoot out to 80 yds. max and the 250-255 gr. bullets work well with 8.0-9.0 gr. of Unique for my standard loads.
For the heavier built revolvers I might use 2400 powder for 250-300 gr. loads for more punch without pressure getting to high.

Best to get a couple of loading manuals and also read up on Brian Pearce articles regarding loading the .45 Colt.

I need to stick with lead bullets. That's what the matches require. I am shooting a Henry BBB. I will play with the unique a little more, see what works best. Seems like 8 to 9 grns. Maybe try some hp-38 with little adjustments as well. Now I have another excuse to reload some more. Thank you everyone for the welcome and the help!

You could also try Power Pistol as it will give you a bit more speed while staying within 14000 psi pressure limits.

Mzzlldrinpa-

Interesting problem you presented! Here some numbers/charts you can play with using 9.0g Unique for 100 yds, 8.5g for 75 yds and 8g for 50 yds. Study them and see if, with adjusts, they can be something to experiment with. Data was made with QuickLoad & QuickTarget. Pay little attention to the atmospherics & twist. Concentrate on "Path to LOS."

However, I'd agree with Esquared for simplicity. Just center punch the 75 yarder. Choose an aim point on the near & far sillywet to compensate for the different POI. Just as you are probably doing now. BTW, is your front sight bead the opposite color of the sillywets (white vs black)?

Powders for comparison only modeled for bullet speed (MV) by QuickLoad & very near 14000 psi:

Cartridge : .45 Colt (SAAMI)
Bullet : .452, 250, LYM LFN 454190
Useable Case Capaci: 28.626 grain H2O = 1.859 cm³
Cartridge O.A.L. L6: 1.580 inch = 40.13 mm
Barrel Length : 20.0 inch = 508.0 mm

Bludot 13.7g, 1311 fps
Power Pistol 10.3g, 1292 fps
Accurate #7 14.3g, 1333 fps
Accurate #9 16.0g, 1332 fps
Universal 7.5g, 1142 fps
HS-6 10.7g, 1237 fps
HP38 7.3g, 1100 fps

I do not know how hard the modeled bullet is. Therefore, approach this "max" with caution. Also, hardcast would be recommended to reduce lead fouling at these MV's.

Well now Mr Wingnut sir. My hat is off to you. That's a whole lot of information. I will be sure to replicate these loads. I really appreciate your assistance. I also thank everyone for their replies as well. I have enjoyed reading everything. This gives an idea of how to proceed. I have been holding off target accordingly but, just thought about the idea of different loads. Gives me another excuse to shoot, load, repeat!
