A reliable source for some consistent 9mm 115 grain RN lead bullets.
My reference jacketed load is with 115 gr Winchester FMJ pushed to near max load data of W231/HP-38; but for lead 9mm loads, I prefer the heavier 125 gr bullets. Why? For many newer 9mm pistols, especially for shorter barrel compacts/subcompacts with stiffer recoil spring sets, you'll need to push the lighter 115 gr bullet to near max load data to reliably cycle with the stiffer recoil spring which may add to leading problem. With proper bullet-to-barrel fit (.001" over the groove diameter of the barrel) and 125 gr lead bullet, I can use mid-to-high range load data with reliably cycling of the slide, very good accuracy and no leading in the barrel.
A reliable source? +1 to
Missouri Bullet - quality bullets, very fast shipping and awesome customer service (you can also buy their bullets from
Powder Valley. Do a search for THR discount to use on MBC website orders).
These are 9mm MBC bullets I am currently using:
A tried and true recipe for your favorite powder and amount used.
Since pistols have different length barrels/ramp angle, groove diameters, leade length (space bullet jumps from the case neck/chamber to the start of rifling) and rifling type, you need to specify the pistol you are using to get specific load recipes. What works well in my pistols with .355" groove diameter barrels may not work so well in pistols with .356"-.357" groove diameter barrels with different rifling/leade/ramp angle that may require different OAL. I would suggest starting out with W231/HP-38 with mid-to-high range load data for most lead bullets with slight adjustments to reflect different OALs used for bullet nose profile and reliably feeding/chambering.
How much you flare the case (measurement) to accept the bullet
When you resize a case, case neck will be reduced smaller than the diameter of the bullet. You need to flare the case neck so the inside diameter of case neck is larger than the diameter of the bullet. For me, I use just enough of flare so the bullet can seat/stay flat when placed on the flare and not shave the side of the lead bullet during seating/taper crimping (I use combination Lee seating/taper crimp die). For this amount of flare, I can feel the flare with my finger tips, but very hard to see with my eyes (yes, that slight of flare). Start with minimal amount of flare and incrementally increase until it works for you. I do not measure the amount of flare with the caliper.
How much you crimp the case (measurement) to hold the bullet
Taper crimp does not "hold" the bullet but neck tension from resizing the case neck does. As many others posted, you just need to press the flare back to the bullet flat. Since case wall thickness is around .010", I add .020" to the diameter of the bullet to determine the taper crimp to use. So for .355" jacketed bullet, I use .375" taper crimp and for .356" lead bullet, I use .376" taper crimp. Below is a comparison picture of different bullet diameter bullets and taper crimps used but shows bulging of case neck to indicate good neck tension.
Any other information would be greatly appreciated. I am new to reloading so don’t assume I know anything!

Lyman #49 ($17) as it is a very good reference for lead load data when powder manufacturers' websites don't always show lead load data for a particular bullet you are loading for.
Also,
2004 Alliant load data pdf is a good reference for lead load data.
