I went to my local scrap yard looking for wheel weights no luck but I did find belt buckles, I seen a sticker on each one that said real pewter. I bought 150 pounds of it thinking it’s real pewter. My propane stove melted some so I think it’s the real deal. I put some in a empty lee pot it was melted at 500f

Nofflneeded - welcome to CB. If you decided to start casting to save money, forget it. You won't, you'll just shoot more.

Pewter has a low melting point, around 170–230 °C (338–446 °F), depending on the exact mixture of metals.
There is a member BNE who will XRF (test you alloy and tell you exactly what is in it for the small price of 1# of pure/soft lead

Casting boolits (lead bullets) properly is a science, once you know the basics, not a hard science.
There is a lot of good information on CB. The Google search (top right of every forum page) is a gateway to all the knowledge on this forum. IF you can’t find your answer there ask the question (Please be as detailed as possible, pictures help http://castboolits.gunloads.com/showthread.php?344661-Capturing-amp-Posting-screen-shots I would be very surprised if there wasn’t someone on this forum that could answer ANY question you might have)

1. Boolits need to be cast .0005 to .003 over the slugged diameter of your barrel for accuracy and to avoid leading. If the fit is wrong nothing else will work right.
a. slugging a barrel (it is safer to use a brass rod or a steel rod with a couple of coats of tape to avoid damaging your barrel http://7.62x54r.net/MosinID/MosinSlug.htm
b. chamber casting https://www.brownells.com/guntech/cerrosafe/detail.htm?lid=10614
or pound casting http://castboolits.gunloads.com/showthread.php?356251-Pound-Cast-instructions-(for-rifle-chamber)
2. the right alloy needs to be used for the velocity and purpose of the boolit (don’t fall into the trap of going with to hard an alloy

Some alloys harden over time

3. velocity the bullet needs to be pushed hard/fast enough to get the proper spin, have the proper velocity to accurately reach the target but not so hard as to be dangerous or strip the lead off in the grooves instead of spinning the boolit..
Powders range from fast to slow, you need to choose the right powder for your application.
Loading manuals list the best powders for certain calibers and boolit weights.
NEVER use any posted noncommercial load data without first checking to see if falls in the safe parameter for your firearm!! There are several firearms out there that can handle much higher pressures than others!!

Real pewter usually has it stamped or cast into the surface of the pewter not on a separate sticker. Most of the fine or trifle pewter I've seen melts around 450F. A higher lead content pewter melts at a little higher temp. Just depends on the amount of lead. 150 lbs is a whole bunch. Congratulation and welcome to the site.

Who can test lead sample with XRF?
