The OP stated that the performance of his .35cal cast bullets are not performing well. From what I know, the first question I'd asked is if you slugged your barrel? It's said that a high bhn bullet can still lead your barrel and not shoot well if your bullet diameter is too small to the bore. And so, find some pure lead, lube it with something like Imperial Wax, and shove it through your barrel with a wood dowel. You can find pure lead from a BP shooter or a fisherman (split shots). Then, find a drill bit that's just larger than your bore and drill a shallow hole in a 2x4. Take your ladle and melt the lead and fill that hole. Then, dig it out, clean it up, use it as your slug. The second thing you need to know is the bhn of your lead. For rifle, you need a higher bhn than pistol pressure loads. I'll assume you're using scrap lead. Cast your cleaned lead into ingots and let it sit for a over a month. I waited up to six months. Why? because the lead molecules are rearranging themselves still. I've experienced measuring the bhn of an ingot hours after I cast the ingot and then months later and the bhn changed. Keep that in mind if you're going to cast hundreds of bullets. With your bhn known, you should shoot for Lyman #2 bhn. Your alloy might not be the same but Lyman #2 is a proven allloy for hunting bullets. I measure my bhn with lead art pencils. The various lead hardness will scratch lead with different bhn. You can use a lower bhn lead, why? The third thing you need to ask is how fresh are my cast bullets? As I stated earlier, the bhn will change over time. You can temper a softer bhn alloy by dropping your PC'd bullet that's 400 degrees out of the oven and drop it in cold water. With a bhn close to Lyman #2 and a meplate, you're good. Why? because a sharp tip will pencil through your game. If you don't have a meplate, file some of the tip flat. Two other ways to get a softer tip is first to submerge the shank of your bullet in that cold water and leaving the front portion that doesn't come into contact with the rifling out. Then take a propane torch to heat it to remove the tempering. I've only read about this. The best test It can think of is take a bullet and squeeze flat in a vice. Then, test the bhn on the tip and shank using the lead pencils. Third, how hot is your molten lead? If you pour your alloy at different temperatures, your bullet weight will vary. Pouring frosty bullets look good but the molecules won't cast the bullets the best. I think I cast my bullets at around 720 degrees according to my lead thermometer. Some online casters recommend turning your pot down until your lead starts to solidify, then add 100 degrees to that. Make sure your pot doesn't run low because that could effect bullet weight consistency. Fourth, how are you pouring your lead into your mold. I've personally noticed that when I poured my lead into the sprue plate hole or wherever so the lead would run it, bullet weights varied. My bullet weights were more consistent if I swirled the lead into the mold by holding the mold at an angle and pouring the lead at a corner of the sprue plate hole. That way, the liquid lead is pouring into the mold like and ice cream cone smoothy than poured into a cup making bubbles. I drop my bullets on a towel or on the ground because the lead bullet will be heated again and tempered after I PC the bullets. I add a gas check to my bullets. I believe that a gas check prevents a bullets base from obturating under pressure. Think of it this way. If you were a human cannon ball, would you prefer to stand on a thick piece of wood plate with maybe even sheet metal added or a cardboard box? Fifth, group your bullets by weight. Sixth, I like to lube my PC bullets using my RCBS case lube and pad that never gets used anymore because of I now use Hornady One Shot. Lubing the PC bullet makes sizing easier. And last, about seating your bullets. I use an RCBS plug. Some prefer the Lyman M die. I chose the RCBS plus because the plug expands the inside case neck diameter .001" under the bullet diameter. If not, I bought a large plug and plan to use a lathe to turn it down. The RCBS plug also flares the case mouth like the Lee die. This is just what I know and do. Some of you already know this. Others may not so that's why I listed it. Good luck and have fun. That's why we are all here.
