Post by rcbmlb@scbglobal.net Wed Dec 30, 2020 2:48 pm

I have 200gn copper plated 45acp and 230gn 45acp copped plated I want to load them. I have been loading them with 5gn but now I am double guessing myself. Does anyone know how many gn's should be used.

Thanks

Here is a screenshot of some data comparing 4 powders Red Dot, 700X, Bullseye, and 452AA.  The gun used was a 10 inch Contender.  Each was run in Quickload to get an idea on velocity differential between a 10 inch and a 5 inch barrel as well as a guesstimate of pressure.  The differential in velocity between 10 and 5 inch barrels was about 75 fps.  The pressures guesstimate for red dot was 13000 psi vs 9000 for bullseye.  So Red Dot is way hotter.

Looking at the chart they are like the powder charts I looked at in my Lee loading manual. What I don't see is a entry for 200 plated or 230 plated using Red Dot powder. Like for FMJ red dot says 5gn. The only powder they show for the 230 plated is Accurate #7,#5 and #2.

Well, you can start from saying 5 grains of what powder you are using.

My assumption is that you are using BullsEye.  If that is accurate 5.0 gr. is indeed what I use with X-Treme plated 200gr flat point bullets. 824fps, 1.20" OAL, WLP  For 225-230 plated I use 4.7gr of BE with 1.18" OAL.

I forgot to mention those were with cast 200 grain SWC and results will be nearly identical with plated.  I have no data with 230s, but I would start at the starting load of 700X and go from there.  Just be cautioned, that Quickload is indicating that Red Dot is a bit touchy.  Seat the bullets .030 deeper and pressures go way up, add .2 grains to a just below max charge and you’re over max and into +P range.  So I keep my loads well down onto the middle range of pressures.  I was born with 10 fingers and I want to keep them, thanks.

I did look at the SWC data, but since I got spooked I just wanted to see what others were loading. My powder handler broke (fell over on the bench) and when I "repaired" it I didn't realize it was not dispensing the correct about of powder. I should have assumed it was dropping the correct amount of powder. Luckily it was light, 3.3gn was what it was dropping. I realized something was wrong when my fresh rounds were failing to eject. Tried a few more and they all had the same result. Boom then no eject. I came home and took a bunch apart with my trusty bullet hammer. The results were 3.3 and one with 2.9. 

That explains why I am asking for others with experience, before breaking the powder handler I had loaded about 4000 rounds.

Goes to prove that you should never take anything for granted.

I use 3.7 Red dot with a 200 grain SWC for best accuracy, Its just over 700 fps.

I checked some of my older data from July 2000 when I was experimenting with Red Dot.  I chrono'd (3) different charges of Red Dot with a lead 200 gr SWC (H&G 68 style) seated at 1.25" and taper crimped at .470"  Colt Gold Cup/Kart barrel.   Steve

3.6 gr  721 fps
4.0 gr  780 fps
4.2 gr  807 fps

When I first began reloading .45ACP I was using 4.0 Red Dot with a 200 LSWC. It was a bit hot compared to current loads for this type of shooting.

I have always used Red dot for plinking loads.  During the last shortage I bought a 8 lb keg (plastic jug) of Promo for $129.00.   I ended up using it up and bought another.  

Alliant Promo is the same as red dot in burning speed by WEIGHT.
Basically its red dot with out the red dots.

Plated bullets use the same charge as cast lead or a 10th more.

If you can’t find RD data, you can use a start load of Bullseye. They are so close that they flip position depending on cartridge and bullet weight.
I like 4.1gn RD with 200gn L-SWC
