41 Magnum Projectiles

[cowboy4evr]

I don't use any chemicals , just chore boy . I used to use lewis lead remover , but it got too expensive and didn't do a better job than just a piece of chore boy .
Yes , slower burning powders do help . Larger cast doesn't increase the pressure hardly any as compared to shooting plated / jacketed bullets . The " friction coefficient " of those bullets is much higher than lead . As they are made of a much harder material and contain no lubricant . There are bullet casters that provide whatever diameter you want . I want make a few phone calls and get what I want , not just take what they sell . Check with Missouri Bullet Co , , Penn bullets etc .
If using cast in 45acps , semi auto's I really wouldn't worry about " barrel roughness " , right now . Get the right fit and don't get caught up in buying hard bullets ( bh18) in the lower pressure rounds (38spl , 45acp etc) . softer bullets (bh 8-12) work much better than harder .

Tell me the secret. What am I doing very wrong?

Am I using the wrong hard cast bullets? Who's should I try besides Berry's, MBC, Meister, or X-Treme.

For years folks have told me that their gun(s) don't lead with their favorite hard cast bullets and I must be doing something (very?) wrong.

All my gun barrels lead, regardless of who makes the bullets or the Brinell Hardness Number (BHN.) Some say my barrels must be rough. Do you think this includes the Wilson Combat, Ed Brown, and Bar-Sto barrels?

As for folks on line, I really don't know. As for locals, Mr. Lewis' Lead Remover continues to drag lead out of their "my gun doesn't lead" barrels.

Seriously, tell me what I'm doing wrong 'cause the Meister or MBC 200 grain H&G #68 hard cast bullet is extremely accurate in the Wilson Combat CQB, Dan Wesson PM7-45, Bar-Sto barreled Colt Gold Cup, and Kimber UC II 45s.

Everything leaves some residue behind, lead, coated, plated or jacketed. Its about degree of fouling. Most leading issues are bullets too small. Even 0.0005" with a hard bullet can cause leading issues at low pressures, So bigger is better. In 45acp, a moderate hard bullet at 0.452" dia will often be fine, brush the barrel, patch it, done. Most commercial cast are too hard for low pressure/Vel.
Nothing wrong with jacketed, especially in semis, but they do cause more bbl throat wear than a good lead bullet in a rev. Why none of my magnums get jacketed anymore. Plated are better, softer so less gas cutting, but they can be really finicky with crimp & vel limits. 1300fps is easy with a good cast bullet, easier still if it is coated.

You could always slug your barrel so you know. Then you get what you need, no more leading.

Thanks for the insight. I don't cast my own so I'm at the mercy of the bullet sellers.

Increasing the bullet diameter should provide a better seal but also increase pressures. Correct?

How about using a slow burning powder?

Regarding Chore Boy, it does indeed work as you describe as does Mr. Lewis' Lead Remover. I've tried several liquid lead removers with limited success. Suggestions?

The slight increase in pressure is minimal. Lead bullets, even hard ones, easily swage to fill the bore.
The other issue with revolvers is diff in cyl throats vs bore dia. Does no good to make the bullet fit the bore if the cly throats are small. In a 41mag, i would want them minimum 0.410", 0.411" better. Any bullet passing thru the smaller cyl throat enters the bbl small & may or may not bump up, thus early leading. You will need pin gages or in id micrometer to measure them, but if a 0.410" jacketed wont press thru, they are probably undersized & lead bullets will be a problem.
Leading early is often a bullet too small. Leading in the middle, could be a rough Bore. Leading at the end, often a lube failure. Why coated often work better, not subject to lube failure. Some jb bore paste can help a rough bore. Also make sure to clean the bbl between lead & plated/jacketed for best results. Copper can snag the lead as it passes over it.

Remember , " Chore Boy " is the secret to removing lead from a barrel . It 's a pure copper scouring pad so just cut a small piece , wrap it around an old bore brush . In just a couple of min's you will remove all the lead . Do NOT buy any other brand as they are usually steel just coated in copper and will harm your barrel . " Chore Boy " is usually available at most walmarts , ace hdwe etc .

Cant agree more.. I had a badly leaded 357 revolver and a few swipes of ChoreBoy cleaned it nicely ... best few dollars I spent

I got tired of being disappointed in the lead bullets I purchased too & their leading. Even one maker's coated bullets leaded but another's didn't. I hate spending $$ for junk & then trying to cope with it. Any leading is too much for me.

I swore off cast lead bullets finally & went with plated for range use. They might require a tad more fine-tuning of their load but they are far less grief for me in the long run, which makes me happy.

I'm not going to cast my own but more power & praise to those that do. I usually go thru 200-300 rounds a week & reloading is enough fun for me.

And yes, typically the slower burning the powder the less apt it is to lead. That is how I finally used up the last of my cast bullets, with slow powder (2400).
