Bullseye load data

[jocat54]

I am new to reloading and have been reloading my .45 230gr plated bullets with 4.8 gr of bullseye and they are working well. My manuals call for 5.ogr (Lyman 49th and Richard Lee 2nd edition).

I thought I would reload some 9mm 115gr fmj and was surprised that the manuals call for the same load of 5.0gr of bullseye, just seems like to much.
Looking for ya'lls opinions.

I am loading using a Lee Turret loader with the powder discs and Lee says .53 will drop 5.0gr--in reality it is more like 4.7 to 4.8gr upon weighing it.

Here is what my books say: Lyman 49th 4.8gr, Speer 4.6gr, Hornady 4.7gr max loads

So yes, 5.0gr seems like too much.

Considering the fact that the bullet weighs half as much, it makes sense that the load data is close. Lower bullet weight equals lower pressure with the same powder charge, but more velocity. The physics support the load data.

Although I found that my Blackhawk likes 4.4gr of Bullseye in a 200SWC(45ACP), I have only loaded my 9mm with Blue Dot. So my personal experience w/ Bullseye in 9mm is N/A.

My only help is that Alliant's (maker of Bullseye) website says 4.7 grains in a Speer 115 GDHP.

Well, I guess I'm getting so old I can't read anymore--Lyman 49th says 3.9gr for 115gr Hp(but they are 115gr fmj)!! Richard Lee's does say 5.0gr though. I loaded up 5 rounds with 4.0gr and they are working well so I'll work from there.

Thanks for the replies

Always be careful with bullseye. It is one of those powders that you can easily double or triple charge the case. . . . .

I loaded up a 50 round batch of 9mm with 4.8 gr of BE and CCI SPP primers pushing 115gr FMJ Zero bullets @ 1.15 COAL and it felt way too hot in my P89 and the grouping really sucked. Nothing at all like the same charge weight of 231.

I loaded a batch of 50 .45 acp with the same charge of BE and CCI LPP pushing 230 gr FMJ Zero bullets @ 1.250 COAL and they felt OK but the grouping was not as good as I get with the same charge of 231. I am going to try some more charge weights with the .45 but I am going to stick with 231 for the 9mm for now.

I've played with a bunch of different powders in .45 ACP (Unique, Bullseye, PowerPistol, Titegroup, Longshot, 231) and I have to say that Bullseye gives me the most consistent results.

The nice thing is that my powder measure setting for Bullseye in the .45 (for 230 gr.) is the same that I need to load Longshot in my .40 S&W (for 180 gr.).
