Can one load lead, non plated, non jecketed in 45acp cases.
Am wondering if they feed into chambers properly.

I run 200 and 225gr SWC through my Kimber all the time. Never had any issues at all.

yes, the oregon trail bullets are good

Back when the .45 ACP was competitive in IPSC people shot millions of the H&G 68 copy bullets a year

Yes the 45acp is almost made to shoot cast bullets in they work great.

Even better when you cast your own for very cheap.

what firearm? cast lead is not recomended for polygonal rifled barrels.

I cast my own 230 gr found nose bullets and they feed just fine in my Taurus PT1911.

Thanks guys
Lead it is

If you have a feed problem. Polish the feed ramp.

Can some other type be used?

I shoot 95% of my 45ACP loads with cast lead bullets.

It does take more care when reloading with OAL and any bulges that may appear.

As stated, Glock discourages the use of lead bullets as well as ANY reloads to be fired through their barrels. My experience is that some Glock barrels are ok with lead bullets and others will lead up fast. Best to experiment if you are shooting a Glock and visually review the results.

Some guys will move on to aftermarket barrels with more standard cut rifling and I've done that with two of my Glocks. I bought KKM after a couple of disasters with Lone Wolf Barrels.

Where do you get KKM barrels from?
