I'm just getting back into reloading after being out of it for the last 20 years and would like to get some feedback on my 40sw loads that I made.
Bullet made from lee 401-145swc mold Measures at 151gr
Powder 6.5gr unique
primer Federal mag small pistol
Once fired brass
my problem is that when I looked at load data for 155 jacket bullets on the Alliant site and the load data that came with my lee dies they both show a max load of 8gr and the lee info says start at 7gr. I thought that 6.5gr would be a low to medium load for a 151gr lead bullet. I just picked up a Lyman load data book for Auto pistols and it is showing a start of 5gr and max of 5.6gr for the lee 145 and 6.3 for the lyman 150gr lead bullets. Any advice on this load would be greatly appreciated.

Looking at the Lyman's 49th edition, it shows 150gr #2 alloy at 5.0- 6.3 gr of Unique. OAL is 1.090". WSP primers.
5.0 grains, 980 fps, 16,200 c.u.p
6.3 grains, 1196 fps, 23,000 c.u.p

2004 Alliant load data (http://glarp.atk.com/2004/2004Catalogs/2004AlliantPowderSM.pdf)
Do you think my load data above would be safe to use or am I pushing to much?

I dont use cast bullets might wana talk to guys here that do but lookin at your bullet weight and powder grns you would be fine with say a 155jhp not sure if they behave the same as a cast bullet,Not sure why you are using magnum primers no need for them in a forty of that style bullet.

My first choice would not be magnum primers but when I went to the store here they had 2 boxes of 1000 left and they didn't know when they would get any more in and all the internet suppliers were showing back orders for all primers, I jumped on them. Unique was not my first powder choice but it was the only pistol powder left and now I have a 4lbs jug of the stuff. I ordered 500 155gr plated bullets from X-treme bullets in January and just got them 2 days ago, while I waiting for my plated bullets I ordered a lee production pot and one of the last 40sw bullet molds I could find on the internet and 30lbs of lead and made my own lead bullets. Now that I have all my stuff I'm stuck working 10-12 hour days six days a week and have no time to shoot them. The more time that passes the more I second guess my load data with the lead bullets. I loaded my plated bullets with 6gr of Unique which in the Lyman manual is in the middle and according to my Lee data its low but I would rather be low than too high.I was hoping someone has used Unique with this weight lead bullet to let me know what to expect.

I was able to get to the range today and shot all my reloads without blowing up my gun :) . The loads I was worried about shot great and were the most accurate of the lead bullet loads I had. The barrel was lead colored after 100 rounds but did not affect accuracy and a few dozen rounds of plated bullets cleaned it right up. I'm guessing my Lyman manual load data is a little on the conservative side. The federal small pistol magnum primers were OK, out of 300 rounds I had 6 that did not fire on the first try, 2 of six fired when fired a second time 4 were dead.

Cleaning lead out of a barrel using plated or jacketed bullets is frowned upon....

Get yourself some lead cleaning cloth

The easiest cleaning method for lead in a barrel is a 40 cal bore mop and some bronze wool or Chore Boy. The mop should be snug to begin with. A few strands around the mop should make it really snug. Fifteen seconds with a few up and down strokes takes all lead out. Do this outdoors because the lead dust is very fine and can be ingested.
