HI ju ok for my airgun slugs I use a bhn tester from lee about $60 usd so where u get ead is up to u , places like zip, roto medals , corbin , sell quality clean soft lead , I use 6bhn for soft slugs and for say heavy powered gun over 250fpe i make lead 9 bhn , I do not use hard lead
I use mny types of molds but most I have made special for my specs for my guns , like the edgun 61 , this is a good weight for my 110 fpe gun ,I make slugs for my 22 royale which I got set at 36fpe I make a 30 grain noe bobs boatail slug for this , and my 25 hatsan which has 68fpe I make a 52 grain slug , I have weights from 28 grain to 180 grain ,I dont do the big bores as my state doesnt allow it so I am ,300 max , id love to do ,308 much more better bullets for this with better BC ,
so the lee tester sits in your reloading press and has like a ball point pen on end of it you put your lead down and hold some pressure for 15 seconds and measure the dent , the places I mentioned sell good soft lead , you can buy at ebay too but its a crap shoot if u get soft lead ,
ohh 1 more thing I am no expert but I have friends who are with making bullets , I have a good friend who is largest manufacturer in world , I make these for me It is my a buisness for me ,
But if you want to dive in and try to do it I can tell you this , you will go threw alot of molds to get a good bullet , 2 measure bores of guns u plan to do , find a good mld builder and make sure u say what end size u want say .254 or what ever and tell hm the type of lead say pure lead 6bhn or if u use wheel weights or 10% tin or what ever as shrinkage is all different
the best mold is exact and doesnt need sizing , but I use slugs for some multible guns so I do make some .002 bigger to resize for different guns
and 1 more tip I made bullets for a long time and I would quench them in water to cool them , this was huge mistake I thought cool them off uick but i was wrong when doing this hardens the lead so 6bhn turns to very hard lead , i dont use hard in airguns but powder burners u want hard lead , so never quench in water
How ever a friend did tell me if you do this and wait 6 months they wil soften like 12 but not back to 6
you want to get many resizer to size your ammo I use lee on my rcbs press , I also like NOE push threw sizers for airguns , they have soo many sizes which we use
I use Corbin swage lube this is best in industry get some a jar lasts a lifetime a drop can lube 100 slugs ,
get a digital scale rcbs, gem, frankfurt are good
as you want to sort ammo by weight , when casting , I believe temps in molds and lead makes them vary up to 1 grain on a 30 vcal slug on a 22 cal mine vary .5 so i package them down to .1 same with my pellets , and I use the heavy and light ones for targets or chrono work
does this help????
