I have had more success with a 257 cal mould done by Buckshot running the lead hotter than usual. No thermometer here. I just trial and error until I get good nose fill out. Mine is a spire point and can be finicky(SP).
A 311 291 HP and a 358156 HP are run the same way and I like the results. I use WW w/ a little linotype melted in for these two and I have been using pure linotype in the 257 mould. With pure linotype, I flux a bit more often, especially when the bullet noses go to pot.
I think I got an image attached to this to show the final outcome of the 257. It is not the best image, but i am still trying to get the hang of the camera.
Do not know if this is specific enough 45NUT, but best I can do at this time and place. I have found that I must run HP's hotter than the other moulds. But I am Not an expert, I am still learning that is why I do not post too often.
Keep trying Rugerman1, best advice I saw here one time was "do not be afraid of mistakes, they can be remelted"
