155 grain lead in 40S&W with unique

jim8115 · July 23, 2011, 04:56 PM

I bought some 155 grain "black" coated bullets from precision. Alliant shows a max load of 8.0 grains Unique for a 155 jacketed ( 1207 FPS). Minus 10% would still be 7.2 grains .. that sounds high to me. Anyone have any input on using unique with 155 grain lead? I have used 5.0 grains of 231 and it shoots well but feels a bit light. I also used 5.5 unique with 180 grain lead, but havent loaded any 155's with unique.
Thanks

2004 Alliant load data shows 6.5 gr of Unique as max for 155 gr lead bullet.

I would not recommend using jacketed load data for coated lead bullets, especially for higher pressure 40S&W caliber.

I would use the 2004 Alliant load data for lead bullet and do my work up from 10 percent below max (5.8 gr).

This is from Precision Bullets FAQ page - http://www.precisionbullets.com/faq.htm

Q: Do I use reloading data for lead or jacketed bullets?
A: Any reloading data for cast lead bullets will work for precision bullets.

Unique and 40 ,you can do better.....
but follow a few grains less than Alliants recipe ,i usually start around
1Gn less than max is plenty for plinking

Hodgdon #26 shows 7.3 grains of Unique as max for a 155 jacketed. that's what I use for my HPs. I'd reduce it to 6.5 and try that with the cast ones.
AA #5 is great in the 40 cal too.
