9mm bullet weight ??

[lonewolf5347]

I run .358 124 gr. Lead TC cast bullets in my 9 mm.
I have some 38 cal. 158 gr. Was thinking in trying them in 9 mm
What do you think on the 158 gr.

Depending on OAL/COL used, I found when using heavy 9mm bullets, bullet seating depth and powder compression is an issue you need to factor in. There are heavier 9mm bullets like 165 gr RN from X-Treme - https://www.xtremebullets.com/9mm-165-RN-p/xc9mm-165rn-b0500.htm

Use of dense powders and longer OAL are two options to consider.

Personally, I think developing more accurate 124/135/147 gr loads is time better spent (and at lower cost)

If I am looking at shooting 165 gr in 9mm, I would prefer to switch to 40S&W which provides much more reloading options.

Dardus went out of business it is hard to find 124 TC bullets in 9 mm diameter .358

If you call cast bullet manufacturers, they may custom size TC bullets to .358" like Missouri Bullet Company - https://www.thehighroad.org/index.p...ponents-on-sale.707473/page-178#post-11161685

Just check out Missouri bullets
They offer 38 cal. TC .358 124 gr.
Wow solve the problem

Nice.


Also from MBC FAQ page - http://missouribullet.com/faq.php

"Q: Can I request special sizing ...?

A: In most cases, yes. Give us a call to place your special order."

Wow! Those are heavies, indeed.

My standard 9mm cast bullets are all in the 150-157 gr range,

Lyman had data for the 158 gr Lyman 358311,

Why in the world would you want to shoot such a heavy bullet in the 9mm. IMO there is no advantage gained and it's probably a detriment. Velocities will drop and pressures will probably rise. To what end do you do this?

All else being equal, yes, heavier bullets will go slower.

Pressure will not rise because that is controlled by powder kind and charge weight. Any and all bullet weights can be loaded to the same peak chamber pressure. Easy peasy.

Why heavy bullets? Different bullet weights for different purposes. Several companies load 158-165 grain bullets in the 9mm. https://www.ssusa.org/articles/2018/8/6/heavy-9mm-luger-bullets-everything-you-need-to-know/

There's even a 185 grain load on the market. https://seismicammo.com/

Don't you know? Us reloaders are a curious bunch and always want to push the limits of uncharted reloading territories ... You never know, good loads have come out of pushing the reloading boundaries.

While I tested and developed good 9mm loads using published load data for Bullseye, Clays, Red Dot, Titegroup, Target, Green Dot, N320, W231/HP-38, Sport Pistol, W244, Unique, Universal, BE-86, Power Pistol, WSF, HS-6, Auto Comp, CFE Pistol along with Vectan and Shooter's World powders; curiosity made me test (without published load data) and develop working loads for Promo, WST, IMR Red and Herco.

Thanks to those testings, Promo now has become my primary general purpose pistol and carbine load powder that works well to often produce 100% case fill loads for more consistent muzzle velocity/low SD rounds for longer range shooting with less bullet drop (even with being slightly reverse temperature sensitive) - https://www.thehighroad.org/index.p...blended-promo-for-more-accurate-loads.841097/

Imagine what led to testing and developing 9mm Major loads that push 124 gr bullets to 1450+ fps without published load data for reference? These reloaders had big balls/foolishness but now we have well established 9mm Major loads that have been proven in many pistols/barrels for other match shooters to reference.

But as I posted, when we go beyond the published load data or test/develop loads without published load data, we must factor in all of the reloading variables, especially for small internal case volume 9mm where small changes can have significant effect on chamber pressures. And also when developing heavy 9mm loads, I would absolutely make sure no bullet setback is experienced which could compress powder charge and increase chamber pressures - https://www.thehighroad.org/index.p...nd-bullet-setback.830072/page-4#post-10926900

Sure velocities drop, but pressures aren't that high. They make an awesome match load when you don't have a power factor to deal with. Just a gentle push, brass falls right at your feet. They sip powder. 2.7 grs is my current amount.

If you're shooting a suppressor they are even better.

But mainly when you ta

getting the big guys to plunk, and still function in the gun, is not easy. some bullet designs work and some don't.

That mold is heavy, but it can be loaded crazy long due to the design.

Same for these too.

I have all three of these molds. The RCBS clone has no lube grooves so it's coming in at 156 grains. When loading heavies it really helps to select the correct bullet profile.
