| I am new to reloading so bear with me. I have two loading manuals and neither lists a load for 147 gr 9mm using bullseye powder. Is there a reason bullseye should not be used with heavier 9mm loads? If not does anybody have any load data? |
| Bullseye is pretty darned fast powder. Heavier bullets usually are pushed by somewhat slower powders, which will give a more manageable pressure curve than fast powders like Bullseye. I'm not saying that it would be "bad" to use Bullseye with those bullets, but if your manuals don't list a load for it, there may be a reason. For what it's worth, Alliant, who MAKE Bullseye, recommend Unique, Power Pistol and Blue Dot for 147gr bullets in 9mm-those three powders are anywhere from slower to a LOT slower than Bullseye. |

GHPorter pretty well summed it up!
Older Lyman manual shows one load for a 158Gr Cast Lead with Bullseye. 3.0 Gr to 3.5 Gr. As you can see there range is tight and not much wiggle room in there! Also performance is much lower. In the 9mm, Bullseye climbs to the top of the heap only when used with lighter bullets 90 Gr to 124 Gr. Unique tops it in most cases while Blue Dot and Pistol Powder were not even on the market when that book was printed (1970). |
