45 Schofield: Will Low Velocity Loadings Get Leading With Laser Cast Bullets
Вставка
- Опубліковано 3 жов 2024
- So the knock on Oregon Trail's Laser Cast Bullets are so hard that anything but full velocity loadings result in barrel leading, often severe barrel leading. But since bullet fit to the gun is much more important than hardness, the question must be asked if Laser Cast bullets can shoot clean and well at standard velocities... Here's a test to provide some data on this question...
45lc is my round of choice, to bad there is not more variety of factory loads. I guess I understand ammunition companys error on the conservative side for Peace Makers owners, but does nother for modern Rugers or Henry Rifle owners. Glad I reload.
living in europe near at the northsea you know rain and wind

In my experience, ANY lead or lead-alloy bullet will leave leading in the bore, regardless of the velocity at which it is fired. Higher velocities generally result in heavier lead deposits. I've been shooting Oregon Trails Laser Cast bullets for as long as they've been on the market and have always had to remove some leading afterward. Shooting a number of high-velocity loads often requires the use of a Lewis Lead Remover to get the grooves fully clear of lead. Leading from lower-speed loads can usually be cleared by using an appropriate solvent and phosphor-bronze brush - and a good measure of elbow grease. I used to shoot mostly lead-alloy bullets, but switched to mostly jacketed or plated bullets just so I didn't have to fuss with lead removal. It can be a chore. I also took to casting gas-checked bullets for use in high-velocity loads in magnum revolver cartridges. The gas checks seemed to cut the leading considerably. Cheers.
Rain, Rain and More Rain.. They are talking snow tonight.. Ugh!! I have a feeling that You and I both know why you would get leading,, even if the fit is right. I'm not going to give it away.. Dave.
Good info . Thanks
i get all my bullets from summers interprises out of mississippi,,,,, i have shot 1000s of them with 0 issues of leading,,,, they are grade 18 for hardness,,,,,, i shoot my 9mm and 45 at around 700 fps maybe a bit more and have had 0 issues
I think the issue is that pre WW2 45 Colt barrels were often .454-.455 inch instead of the modern .451, meaning properly sized bullets for the modern barrels are grossly undersized for older barrels. Older revolvers are well known to have accuracy issues with jacketed bullets because the grooves don't properly bite into the jacket, and where the whole issue of severe leading from very hard cast bullets is a huge problem. Harder bullets are better when you have the proper size of bullet, but soft is always better if you have an undersized bullet; thus these would probably cause severe leading in an old 45 Colt revolver, because they are under size, and are way to hard to obturate. Swage factory bullets were a half assed means of solving the problem, even though they don't work as well as a properly sized .454 or .455 bullet, they will at least obturate to seal the barrel, prevent leading, and give at least some semblance of accuracy.
If one cannot obtain or cast the properly sized larger bullet, than a swage, or better yet, soft lead hollow base would be the next best thing to solve the issue. In your case study, with a modern barrel, I'll bet your barrel will turn out well, because its modern and tight, with the only issues being the cylinder throat sizes, and also those damned hard lubes they put on commercial bullets. I've dug out countless Rim Rock bullets out of my rubber mulch trap perfectly intact, including the thick, heavy red lube that just doesn't want to burn in light fun loads.
The Webley revolver used .455 dia. The British used that gun and caliber years ago.
Yep. And, when you talk to people who slug the bores on those
revolvers, the groove can run from .452-.455 caliber, with .455 being
the large standard. Keep in mind, with all old guns, barrel making was
not as good as it is today, meaning groove diameters varied greatly.
This is why any prewar gun should be slugged before making bullets, or
buying bullets, for reloading. Not just the 45 Colt or Webley,
basically all should. This is one of the advantages of the soft lead
bullets of the era, and why hollow base bullets were so well liked, was
because they could swage properly, even if you didn't have the perfect
sized bullet, and the soft lead wasn't a problem at the low velocity and
low pressure of those old loads. We certainly take for granted the
good barrels we have today, and when a manufacturer tells us what a
groove is, we don't have to second guess it.
kingduckford - Thanks for posting from your knowledge and experience... always good stuff. What you post is the reason the Remington 148 grain HBWCs were so popular...They were .358" and nice HB. I bought those 4000 at a time, and they have not been available for the past 5 years... Have a great day, FC Steve
Hey FC Steve, I have some 38 special 125 grain factory cast lead bullets ( store bought ) which are already lubed. Would it be bad to powder coat them in the normal fashion ?
seems like youve gotten more rain in the last couple months then ive seen u get in a couple years up until recently
the baddest - When we were in drought - we got very little rain. Now we are getting quenched, and they are not declaring end of drought yet - with all the water demands in CA, they will never declare we have enough water. Best to ya, FC
Is the proper lead bullet fit ~ 0.001" over what the barrel slugs at? Is that the traditional convention? Thank you.
the 44's lead my S&W and bulldog at 900 & 700 FPS ( unique ) , a pain but I bought 1,000 , they shoot OK , the lead is at the breach end . .............. so do Horn HPWC & Speer HPWC & SWC ?????? I started using Barry with light crimp or OVER top of the shank , deep set into the case . The barry plate is easy to cut & act as speed brakes . Dillon 550 , Just Sayin !
Are you familiar with hercules hi-vel2 powder also have h450 need a source for data if you can help
Looks like a GREAT test!
gman77gas - Actually, the bad leading with Laser Cast bullets is the answer to the question - Why not just cast everything with linotype to prevent leading? - as if hardness was the most important factor to leading prevention. Cast bullets fitted to the gun is much more important. Best Regards to ya, Gary - FC Steve
So fc45lc do u have info on how the laser cast bullets are made
don't believe so. Laser Cast mis not pure lead.
