300aac Cast or Plated
I have a 300bo pistol with an adjustable gas block. Anyone have any issues with the cast (lead fragments) causing issues with the gas system?

Re: 300aac Cast or Plated
Thanks Tim, trying to make up my mind. I can get 220gn. plated from Everglades with free shipping or save 50 and get cast.

Re: 300aac Cast or Plated
It will lead up your can.
Run jackets, plated, or coated. Easiest way to see it, look at the amount gunk inside 22lr cans after a few hundred rounds. And they are a lower pressure round than 300Blk.
And anyone who says they run a hard cast and not lead up a can either doesnt shoot it or its so hard an alloy it may as well be jacketed lol
Now velocities will play a roll in that outcome as well. 300Blk subs are low pressure and low speed rounds. But you will still get fine vapor of lead that will build up on you can's interior. Supers will be even more.
Personally wouldnt run a gas check on a cast round through a can.
One solution, get a can that can be taken apart to clean, and cleaned with hazardous chemical that will dissolve the lead. And then dispossing of said haz-mat remains.
Or made of materials that can withstand being sand blasted.
Now you're limiting your can selection by not having a welded system (personally a fan of welded cans on rifle calibers).
In short, it can be done.
Just make the right selection for the intened job and loading wants.Last edited by Nate7667; February 20th, 2018 at 11:33 PM.

Re: 300aac Cast or Plated
Back to my original question. I'm not a fan of cast but started a listing for a group by on the forum. Had a response from another user who coated cast projectiles. I'm looking at the bulk 220s from everglades. Any thoughts. He's indicating a savings of 50 per thousand. I'm pretty anal about cleaning and maintaining and would hate to have to clean out the gas system due to lead fouling.
