Good info. Thank you.

Thanks. That all makes sense.

Thank you for your input!

Thank you for that info!

Thank you! Not long winded! The more info the better and I appreciate everyone's input on their experiences. I found a chart listing the coal at a mere 1.060 and one for 1.050 for the flat point 124 grain bullet. I thought those were really short, but guess not. I was originally figuring around 1.083 an additional 0.023 compared to 1.060. Is 0.023 really much of a difference? I don't know. Maybe I'm being too picky or too precise?

Thanks for being patient with me. Those are some crazy pictures! These bullets are hollow base, so that's a plus as far as pressure goes (I think). I am seated a bit shallow at a COAL of 1.083 vs the listed COAL of 1.060, so I shouldn't have any problems with pressure (I think). The bullet is seated in the case about 0.200, which seems to be deep enough (I think)! I'm trying to keep on the low end as far as the powder goes. Then I can see how it works out and go from there. Thanks again....

I'm no expert here by far and I'm just getting back into reloading, but shouldn't there be a minimal accepted seating depth? It shouldn't be too deep or too shallow, no? At least have an acceptable range of depth. As I stated before at a COAL of 1.083 the bullet is seated at 0.200 depth into the case. How do I know if this is an acceptable depth? If these are dumb questions or I'm looking at this in the wrong way, tell me. I'm here to learn.

Thank you. Yes, I finally found that exact measurement in my extensive searches. Finding data like this is really tough.

These HBFP-TP bullets measure .536 in length.

These Berry's bullets come in a nice plastic box. You'd think they'd put a loading chart inside the lid of the box. At least give the approximate OAL.

With these flat point bullets loaded at an OAL of 1.083 I have 0.200 seated inside the case. Does that sound reasonable? These are hollow base, so I guess that's a plus which may help keep the pressure down...I guess.

Thanks for the responses. PaleoMan: I'm having a hard time finding load data. For these flat point bullets. They are Berry's 124 grain HBFP-TP. Because they are flat point they are much shorter than a round nose, obviously. When I seat them, 1.083 OAL seems to be a good guess, but I wanted to get some opinions. And to make matters worse, I'm trying to use up powder I have which seems to be extinct these days. I have 2 pounds of Bullseye and probably about 3 pounds of Solo 1250. Ancient stuff from what I can see!

Forgive me if I don't know the proper terminology. 9mm, 124 grain, Berry's Hollow base, flat point, thick plate (HBFP-TP). This is a plated bullet. It does not have any lube grooves. I'm wondering what a safe seating depth would be. I want to make sure I seat the bullet deep enough. I did the plunk test with my barrel and it's plenty fine even with very little of the bullet seated into the case. It definitely needs to be seated deeper. Anyone know what an acceptable depth would be? I want it deep enough, but not too deep where it builds too much pressure. Thanks, Joe
