question about bullet type and load

[italian biker]

Hey all, I use Hogdon Universal for my 40 with a 155gn Berrys plated flatnose bullet. I would like to use Universal for my 9mm with a 115gn Berrys plated round nose. Hogdon specs out two 115gn bullets with Universal. One is a lead round nose, the other is a Speer Gold Dot hollow point. Berry's web site says to use the mid range of a jacketed bullet for their plated bullets but to use the same bullet profile. I understand there would be a difference between jacketed/plated or unjacketed lead bullets. But I still have a few questions for the more experienced reloaders.
1. When they use term "bullet profile", do they mean bullet type and weight or just weight? Which leads to question 2.
2. Is the bullet nose type a major factor when powder companies list their specifications when it comes to safety.
3. And would loading a plated round nose in the mid range of what Hogdon says for the speer bullet be safe?

1. They mean weight obviously, similar construction (Plated, Lead, Jacketed) and nose style, which can affect how deep the bullet is seated.

2. Only as much as it affects how deeply a bullet is seated in the case.

3. Yes.

Some plated data:

I'll look up the height of the speer bullet and compare it to the berrys. Seating it to low is a no no, not seating it enough, improper feed. For each caliber I reload, I make and keep a dummy round for adjusting the seating die and compare overall length to a factory round with the same bullet weight. I usually use flat nose in my 40's, but Cabelas only had the round nose 9mm berrys in stock when I was there. These are going to be practice rounds anyway. All my defensive carry rounds are factory hollow points.
