Hi all,

I've been reloading for a couple years, always factory jacketed bullets.

I have an old Enfield #4, the barrel slugged at .314 and I got a box of .315 200gr cast bullets from MontanaBulletWorks.

Now I'm trying to find load data and all the data I've found stops at 180gr. I have Varget, H335, H4198, and H414. I am really hoping to use the H335 if it's plausible as I have a large quantity and only a little bit of the others.

Does anybody have sources for safe load data that I could use.

Thank you so much for any help you can provide.

I'll just comment that a cast bullet needs to fit the throat, not so much the bore, so if you get leading and poor accuracy, possibly the bullets you have on hand are not large enough in diameter. It just depends but a bullet only .001 over *bore* diameter may very well be undersized.

Best of luck and I hope I am wrong, but, if you don't have great results with these bullets, you may want to try to source some a bit bigger, ideally matched to a measured throat diameter, failing that, just go up a couple more thousandths and see if that helps.

Would hate to see you try these and not be impressed with the results, and then decide this whole cast bullets in rifles thing just won't work for you.
