I have been using 3.8 g of Bullseye with 124 g AIM copper plated bullets and had good luck so far. None of the three books I have give much data for 124 round nose copper plated bullets with Bullseye powder. Does anyone else use 124's and if so what is your recipe for just regular shooting?
Load for 9mm with Bullseye - 124 G
- Thread starter Northof49
- Start date
I haven't tried it yet but have a lb of Bullseye to try.
What I find is that starting load (give or take 0.1-0.2gr) for FMJ for bullet weight usually works with plated bullets. So, I usually load with starting load and run them thru chrono to see velocity, adjust from there.

I'm not familiar with the AIM plated bullets,here in the US we have the Berry's and Rainier plated bullets probably one in the same company. Both web sites list the bullets MAX velocity to be kept below 1200 fps. they both state to use equivalent weight Lead bullet data with there bullets.
You can also use equivalent jacketed bullet data,just take the MAX charge listed for the powder and reduce it by 10% and that is your adjusted MAX charge. Example the Alliant web site load guide list 4.4 grs. Bullseye as the MAX load using a Speer 124 gr. GoldDot HP. Using the plated bullet minus 10% your new MAX charge would be 3.9 grs.
I use 4.0 grs. but I shoot my 9mm's from a Ruger 357/9mm convertible revolver.

I think the concern is more about bullet hardness. copper coated bullets wont melt, deform, or lead your barrel like lead bullets. as I understand, the platting on these bullets is quite thin, and doesnt do much for structural integrity.
your milleage may vary.
Lead bullets won't melt or deform either. The major cause for leading in barrels is can be a rough barrel, gas cutting due to the bullet being sized to small, a barrel with copper fouling in the grooves or to hard a lube. Too hard a bullet will lead just as much as a soft lead bullet depending on caliber.
I have shot thousands of lead bullets in my 9MM with nary a sign of leading.
To the OP you can use data for plated bullets when shooting lead with similar results.
There is a very good article on loading the 9MM on the Cast Bullet forum under Pistols.

I like 231 only because it meters so well in my Dillon Powder measure and with the right load is very consistent Unique and HS -6 are very good as well.
Send me a PM with your email address and I'll send you my spreadsheet with my loads I have tested over my Chrony. all are within Manual specs. You might find it useful. Look for loads with low SD's. Each load indicates the ggun it was shot from so you should be able to match up a load with your gun.
