Over weight for caliber

Rainy and cold outside. Wind blowing. Time to start a good heated discussion.

When in the Army, weigh-in time was dreaded. I was always too short for my weight and it plagued me all of my career. Never could grow up much, just bigger around.

The same goes for cast bullets except they’re too small around for their weight.

I’m a firm believer after 60 years of bullet casting and loading that there is an optimum weight for each caliber. I can hear the roars of protest now.

Cartridge manufacturers over the years have spent a lot of good money to research this and publish the results and in addition put their money where their mouth is to produce guns and ammunition to these specifications for sale to you the user.

.32s should cap at 100 grains

9mms at 125 grains

.38 Super at 130 grains

.38 Special at 158 grains

.357 Mag at 158 grains

.44 Magnum at 240 grains

.45 Colt at 250 grains

After these I dropped out of the race as things got too heavy and wild.

Basically, these are the weights manufacturing has decided over the years that are optimum for the caliber.

Then us bullet casters got into the act. Not satisfied with being able to change the shape of our bullets, we decided to change weight as well. Here, we got into trouble.

For years we went along happy turning out accurate, hand made economical ammunition. My first .38 Specials were Lyman 358495 wadcutters. That’s the only mould my local gun shop had in stock. I used it for years and was happy. Later on I saw a SWC mould and had to have one. Still good.

Then some Idaho cowboy with a big hat decided we needed a big 173 grain Lyman 358429 so we could shoot long range. I got that and it was good. About this time, the police departments decided that bigger was always better so they brought out the 200 grain RN Police load. That’s when things started to go bad. While good for a manstopper when you had to, it left a lot to be desired as to velocity and trajectory. I went back and followed the cowboy.

Them the cowboy said, you need a .44 and since .44 Specials were scarce, it was a magnum. Of course, the cowboy’s favorite bullet was the 429421. Again, it was very good. Then an outfit called SSK started making 300+ grain bullets and it was so good that I dropped out and went back to the cowboy. In the meantime, the cowboy said, anything SSK can do I can do so he sent designs to Hensly and Gibbs and in my mould drawer sit a #326 and a #328 H&G mould. 275 and 320 grains respectively. This was so good that I couldn’t stand it but keep a box of each loaded in case the bears decide to raid my garbage can. Every couple of years I’ll find an old refrigerator in a gravel pit and shoot them up and reload waiting for the bear that hasn’t showed up for 17 years.

My point to all this gibberish is that each caliber and firearm are basically designed for one weight bullet at an optimum safe velocity. We get tempted and want to improve on something that works at a loss of efficiency and in some cases safety and may produce a trajectory that our sights may not compensate for.

Fine if you want a heavy load for defense or a specific purpose but otherwise, you’re safer to stick within the design parameters for the caliber./beagle

Maybe, possibly but that doesn't mean going in a different direction won't/can't work and be safe. I won a California combined NRA/IHMSA state championship in revolver class with a 357 mag and the RCBS 200 gr fp. Shot a perfect score of 60 out of 60 out to 200 meters. That RCBS mold cast a bit heavy and with lube and GC weighed 212 grains. Just a bit over the industry norm of 158 grains.

You're not going to get any protest from me.
I'm solidly in your camp.

When you’re constrained by a maximum safe pressure, a limited distance over which you can accelerate the projectile and some optimal twist rate that works well with the mass and velocity available – there’s going to be some sweet spot in terms of projectile weight.

It comes down to basic physics. You can trade mass for velocity or velocity for mass. There is no free lunch.

What surprises me is everytime someone loads a heavy for caliber projectile in some cartridge, they act as if they are:

  • The first person on the planet to do that.
  • That they have simultaneously discovered Shangri la, El dorado, and cold fusion.
And then they seem to ignore the basic physics involved.

Standard weights for cartridges developed FOR A REASON.

The engineer/appraiser in me says it more of a range vs, here's your bullet... and I hear what you're saying, and mostly agree.

For example: 9mm... 115gr to 125gr, 30-06... 150gr-180gr, 5.56mm 55gr to 77gr.

Yeah but P&P what does reason have to do with it?
I’ve been shooting that 44 SSK at 310 or 320 don’t remember, but since the yearly 80’s. I like it, but my reasons are the same for heavy for caliber bullets that I work up for my handguns. I want maximum penetration at the muzzle of my pistol and a little ways beyond.
Now for every day use, I agree with you 100%.
Oh yeah, I’ve got a 358 200 SSK as well but I’ve been sitting on it for 40 years but it’s on the short list.

light weights are awesome on varmints.
got a rock chuck pissin you off that lives 300yds. away?
break out the 25-06 and some 75gr hornady's at 3500 fps, or the 7X57 with 100gr. hollow points at 3-K.

not too helpful if it's a black bear that holds a grudge though.

i also tend to stick pretty close to normal bullet weights, but i also tend to keep things reasonable and just move along to another case if i need more.
the 45 colt with 275's are not enough you say, then the 45-70 is sitting right there waiting.

I dabble in a range of weights. I usually am at the normal weight or slightly heavy, occasionally slightly lighter. I very rarely go "heavy" for caliber though. Course... I like my bullets to hit close to where my sights are pointed without much fuss though.

I go as heavy as 270 in 44 Special and 44 Magnum. I generally stay in the 250ish range though.

Getting older, I have standardized on bullet weights and designs per caliber. Most are near the factory design and velocity. In the cases where I have several firearms in a caliber, I might have two seperate molds if one firearm is strictly for target.

I now believe the experienced reloader realizes the powder measure goes down as well as up. Also for rifle competition, one custom mold that fits the leade is better (and cheaper) than sorting through seven or eight factory molds in hope that one might shoot better.

My pistol loads are at or near the standard velocity. If I need more handgun power, I've got the .44 Magnum. If I can not get the work done with the .44 Magnum, I shouldn't be shooting it.

I shoot mostly 150 grain 358477 out of my S&W 686 but sometimes the 173. Guess I need to get a 158 but don't know which one.

There are places for heavy for caliber but that doesn’t mean they are the answer for all situations.
Rick mentioned a specific situation where heavier than normal worked well and was a good choice. Would I extrapolate that to me using a 200 gr bullet for my every day 357 shooting? Hell no

Too often shooters take a solution for a very unique form of shooting and try to make it the norm.

At the casting bench in the sky. RIP Bret.
I tend to shoot medium to heavy for the cal. For instance, most of my 308 stuff is done with an RCBS 30-180FN, weighing more like 190 in my alloy. But, I also like the 311440 at 150-ish grs and the 311316 at 115-ish. Pend'z on what I want to do with it. Same with handguns. Hard to beat the cowboys 429421 in any 44, but there are some GC moulds and a WC or 2 here on different weights.

Maybe the idea is that for MOST reloaders there is a more or less optimum weight per caliber, but those of us with a more experimental bent tend to ere wildly across the spectrum of weights and designs?

Exactly and the reverse is also true. 158 gr bullet in the 357 is also not the answer for all situations.

When I started casting, the "extremes" were like a siren's song to me.
"extremes" = heavy/light, fast/slow, quiet/loud, brightflash/retardedflash.
After plenty of failures, I became a middle of the road kind of guy.
the end.

If anything, I tend to NOT go light, but not ridiculously heavy.

Like @JonB said - HEAVY was a fascination for me since I was a kid, but that came from pulling down early "small-bore" military cartridges - the 6.5s, 7s, 8s, our own 30s. I never saw the need to push them hard though, because they were heavy - and long.

Since starting the great purge several years ago, not even moulds were safe and I think my selection of "keeper" moulds might tell what my real preferences are better than what I THINK they are, so here goes (BOLD would be the keeper if I further narrowed things down to ONE mould per cartridge):

223R, 1:12 - Jacketed only, 50, 52, 53, 60 grains
222R, 1:14 - Cast only, 50 and 55
30/30, 1:10 - Cast only, 118, 165
357 Mag, 1:14 (revolver 1:18/carbine 1:14) - 158, 180
357 Max, 1:16 (carbine) - 180, 190
44 Special, ?:? - 200, 250

So as I began to make the tough decisions, based on being objective through experimentation, I don't really lean all that much toward HEAVY. I don't really consider the 180s in the 357 Mag revolvers "heavy," because I keep them sub-sonic and don't really load the 357 as a 357.

My best friend likes launching fence posts.

When I started my 357 Mag revolver/carbine experiment back in 2009(?), the original plan was to find ONE mould which would do the most, from plinking and small game to deer, to get away from 125s for the former and 180s for the latter, and then all the moulds for the in-betweens.

I as CERTAIN that a 158 was going to do it and tried a few I liked a lot, but just wasn't seeing the accuracy I wanted at 50 to 65 yards with the 158s, but the 180 is just killin' it across the board, from light sub-sonic (suppressed) to moderate general purpose and even when pushed really hard in the carbine.

Still irks me that I was so wrong on that one, because it was SO obvious that one of the 158s would work for my broad application.

To be fair, I am asking a LOT of ONE bullet, but if I really had to go to ONE mould (my eventual goal), results dictate that it will be the 360-180 WFN, from NOE. I may sell off other moulds and send this one to Eric to have tow of the four cavities fitted for cup-point and HP pins as well.
