Bullet type matter as long as same weight?
 
When reloading pistol ammuntion does it matter the type of bullet as long as they are the same weight. Example, Can I use the same loading data for a 125 gr Lead Round Nose as I can for a 125 gr Full Metal Jacket? I know that loading lead one should stay under 1000 fps.

Don't you have a reloading handbook?

1000fps is a rule of thumb, but not always correct. To cycle my 10mm w/ 175 or 180gr cast lead I am well over 1000fps. You did not state if it was for a semi or revolver. I use W231 for cast lead in most pistol cartridges. The burn rate is key in semi auto's, Revolvers being more forgiving Unique work well also.

You cannot use Jacketed bullet data for lead bullets. Lead is slicker and will shoot faster for a given load than a jacketed bullet.
Lead round nose from where? My 125 gr hard cast lead round nose is routinely shot at 1150 fps and I have no problems.

Same weight? How about length. If you have 2 bullets the same weight but different lengths I would think that ocl would come in to play.

If I am loading lead and the books dont have a lead load for the wieght I am using I will use the starting load for a full metal jacket bullet. I do not use max for anything but what is listed.

Yes, Hornady and Lyman, plus a fair amount of hand-load data I have found on the Internet from powder manufactures. Inconsistencies in the data available from these is why I asked the question in the first place.

I load for both semi autos and revolvers. .380, 38 spl, 9 mm and 45 acp. Thanks for your input on this, every little bit helps.:D

Redsho, check out Lee's Modern Reloading manual. they list a lot of specific lead bullet loads for the pistol calibers.

Pushing lead too fast results in shearing. Lead will build up in the rifling, destroying accuracy and possibly causing over pressure.

But slicker is kind of right;)
