I picked up some conical nose 125gr hardcast 9mm bullets.

My problem now is with OAL.

If I load the bullets to the OAL for round nose (about 1.15"), then the bullet is not very far into the case.

In fact, that ring around the bullet with the lube stuff in it, is not even into the brass all the way. That just doesn't seem right. What am I doing wrong? Should I seat it deeper? Is it okay to not seat the bullet deep enough that the lube ring is into the case mouth? It seems like I should at least push it in far enough to get the lube ring into the case mouth, but I don't want to seat too deep and get high pressures.

What OAL do I use for these funky cone-nose bullets?

Is it a bad thing if the lube ring is not all the way into the brass?

Thanks!

The pressure of the load is a function of the space for the powder. If you seat the bullet deeper, the pressure goes up. I wish they would give the overall length of the bullet they loaded.

What powder?

(Normally, but NOT ALWAYS, safe to shorten OAL some to get lube ring FULLY inside case. Try OAL 1.135+/-.005")

Thanks, it sounds like I should try to get the lube ring inside the brass.

If I put the lube ring just barely inside the lip of the case, the OAL is 1.17". Even at that, you can still see the edge of the lube ring peeking out.

I am still trying to make my loads with 6.7gr Power Pistol at 1250fps. I was hoping to make them a bit long.

Is there anything wrong with NOT getting the lube ring into the case? What is that lube ring for?



I am thinking I should have bought the round nose bullets, which would have been a better (shorter) bullet for this job. I don't want to ship these back, so now I have to shoot up these 2000 cone nose bullets I got.

I cast my own 124 gr truncated cone bullets and Dillon has a NICE approach seating them. (I seat mine to 1.060")

Dillons seater die has an insert with a round nose seater and -flip it around-and a flat none seater at the other end. And by golly, you can switch from round nose to flat none without making any changes iun die position, and it works REAL well.

I wouldnt use anything past 6 grains of power pistol in my 9mm 124 gr CB loads--it just makes more fIRE at the muzzle and produces leading. 6 gr. yields all 10 rounds within a 3' bull at 50' and NO leading at all. Exceeding 6 grains of Power Pistol just makes more fire at the muzzle (kinda fun) and the recoil more enervating, and since I like to shoot a couple hundred rounds a session, I go for the more modest loads since that paper is killed just as good with 6gr as with 6.7

You'll like the truncated cone bullet...it cuts nice neat wadcutter style holes. Knocks pins down quite well!

Like Yodar, I assume you mean a truncated cone bullet. Oregon Trail (Laser-Cast) has a 122 gr. TC bullet that sounds very similar to yours. In their load manual they suggest 1.070 OAL.

Thanks for the advice!

I am still confused as to what the lube ring is there for, and whether it matters if it is seated inside the brass or not.

Thanks!

Lead bullets are almost always seated with their lube rings inside the brass. I don't know of any exceptions to this, but ya never know.
