Should I worry about the ring?

Should I worry about the ring on the nose affecting accuracy?

I would say out to 100 yards probably not? The question is how did the ring get there? If it is from using the bullet to compress the powder then I would suggest getting a compression die instead. If it is commercial, I would try to find out why?

Probably not. If you were shooting long range the flaw "may" affect it, but I'd highly doubt it for up to 100 yards. My opinion based on my experience.

I read your post in another section. If you can't buy a 45-70 round nose seating stem, try a 45 acp round nose seating stem. A friend with a lathe would be helpful.

Thanks, I wasn't sure how much traffic it would get here.

Probably going to have a good bit of leading with that. For the seater stem to leave that much of a mark on a bullet it's liable to be compressing and changing the diameter and overall shape of the bullet nose.
I'ld suggest you use an M die to expand the case a bit more so the bullet doesn't fit so tight in the case, or shooting the cases without resizing, or if loading blackpowder compress the powder before seating the bullet.

Thanks for the good advice, the alloy I used has a BHN of 10. The same for a 30 to 1 alloy. Its new brass, so I'll look forward to not resizing it. I also compressed the powder before seating, I also used a grease cookie. A big ole ball of Grimstache's special blend.
At some point I'd like to be able to make rounds at the range while building a load for my baby. I think I'm the youngest guy at my club with a Sharps, everyone thinks its my Dad's.

I've seen that ring from two causes. 1) Wrong top punch in a lubrisizer. 2) Wrong seater in seating die. If the bullet is correctly sized, alloy correct, lube is good, load is good, bore is good, etc., etc., that ring is only cosmetic and will have little or no effect on accuracy or leading. It seems that with the soft alloy, your seater is wrong, so get a better fitting seater for the RN style. Also, it should not take much pressure to seat the bullet if your case neck has been sized/expanded correctly. If you are not using an M die or using one incorrectly- use one and adjust it so the small, short step barely enters the case mouth--- just enough so the bullet base can be pushed in by hand prior to seating. Good luck!

fouronesix gave you some good advice. I had the same problem when I first started casting. I was using a softer aloy than you. Good Luck.
