9mm Luger 135 Grain!?

[Shanesmyname]

Howdy y'all! My father recently bought 1000 bullets of Xtreme 135gr 9mm projectiles. And I can't find any reloading data for 9mm Luger using that weight bullet. So should I load them to 124 gr spec, or 147 gr spec, or just not use them? Also, I want to be using them for a 9mm Ar-15. And the powders I have to reload are Bullseye, and Power Pistol. Thanks!

Use 125gr data, but use the starting load as max. This means take a starting load, reduce it by 10% and work up.

I would use data for the next HEAVIEST bullet.

+1, use the 147 grain.

[mulyhuntr]

Use data for 147 and work up from there.

Thought I'd chime in here fellas. I just got 500 bullets each of Xtreme 55gr FMJ .223 and 135 grain RNFP.

The only pistol powder I have right now is CFE Pistol (about 2.5 lbs. of it).

I've got good loads with their 147 grain RN with 3.9 grains @1.128'' and 4.2 grains @1.152".

For these 135 grain RNFP bullets, I was planning on starting at 4..2 grains, but I figured I'll probably end up at 4.5 grain of powder. 124 fmj max, according to Hodgon is 5.2 grains while 147 fmj max is 4.2....4.5 grains is smack dab in the middle, as is the bullet weight between those two.

My Lyman 49th doesn't list this bullet weight at all.

Any objections?
Any one with experience using these bullets?

Are you sure you do not have that backwards? I read to NEVER use load data for lighter bullets but instead it was okay to use data for the next heaviest bullets.

I think the reason is because one way can give you too much charge, but the other way can give you an undercharge and that is safer to have an undercharge then an overcharge apparently. :\

Just saying, I can get the BoLee reference and the BoLy reference if you want.

I agree with you that is safer to use a heavier bullet's data when working up from scratch. An undercharge by a few tenths of a grain would only result in maybe a failure to eject.

I think J-cat is referring to 125 grain cast lead bullet. Even though it is lighter than the 135 grain Xtreme, it's still going need less powder than a 124 grain FMJ to achieve the same velocity because it's copper plated.
He also recommended reducing the minimum charge by 10%, which is essentially a 20% reduction of lead data, for a bullet that is only 10 grains heavier. Sounds like it ought to be safe to me.

The OP should probably start at midrange/max 147 grain data and work up from there. I don't like going to the range to shoot only 20-40 rounds out of two pistols. This next go around, I'll load up more and be prepared to pull bullets if necessary.

I'd work up from125's like J sez , at least your pistol will be functioning while your working up your load.

[stilly]

Sounds legit. As long as we are paying attention to the little details that could make a huge difference in how things work, it should be okay either way. I do not think that the BoLee made any difference between lead or j-word bullets when jumping to the next heavier/lighter, it just states NEVER to use bullet data from a lighter bullet. PERIOD. Things like this make me mad at the way they make that damn book. They should have made a note and differentiated between the two...

Use the data from 147's, reduce by 10% to start. The problem is case capacity and pressure. The longer bullets reduce capacity and pressure builds quicker. That's why charges are actually lower for heavier bullets than lighter bullets, especially in smaller cases like 9. In a 45 not as much an issue because there's a lot more room. I use 5-6 gr bullseye in most my 45 loads. Which gives lots of extra space. I use 5.7-6 gr of either AA#5 or power pistol in the 9. So basically I'll have the same grains of powder in two different cases.

If they're cast bullets you'll want to go lower on velocity anyways. So start with the bullseye and I'd recommend starting at about 3.5 grains. Then work up from there. It will probably cycle but if it doesn't go up .2 until it does.

Alliant lists 4.4 of BE as max for 124's. Lists 5.0 as max for PP for 147's. If bullseye doesn't appeal to you try PP (which I love in my 9's) and start around 4.5. Then go from there.

Just a curious question, why get such a odd weight 9mm bullet and 1000 to start with.
