- I used 158g SWC lead bullets for my "extremely heavy" projectile
- experiment in 9mm. The pressure signs with HS-6 were acceptable,
- but the mechanical problems with making it work are a BEAR.
- I was using a NATO-spec throated barrel, or else it would have
- been a totally lost cause. Even then, the bullets have to be
- seated so deep that the case sides bulge. Many of those
- cases had a large enough bulge that it was impossible
- to get them to chamber.
-
- If you are looking for accurate, funtionally reliable
- loads in 9mm, stick with 115 to 124 grain projectiles.
-
- I've tried a lot of different bullets,
- and have had the least headaches with 124g lead and jacketed
- projectiles in 9mmx19.

-
- Regarding using 4.6 grains of BE (?Bullseye) for all your loads:
- If you hold a powder charge fixed and increase the bullet
- weight, the pressures will go up.
- Conversely, holding the power change fixed and dropping the
- bullet weight will make pressures go down.
-
- As long as your powder charge is under maximum for your
- heaviest bullet weight, you can get away with it
- (within reason).
-
- I strongly suspect your 4.6g of (?Bullseye) with a 158g
- lead projectile for 9mmx19 would have been OVER maximum.
- Most of the 147g and above data for 9mmx19 uses slower
- burning powders.
