My RCBS 45cal. 230gr.Rn mould is dropping bullets weighting 233gr. from straight
WW. Will this be a problem? I only load midrange loads.
Thanks,
John

No problem, most bullet molds are calibrated to drop weight with an alloy some what approximating the Lyman #2 alloy. Wheel weights are slightly softer and therefore a little heavier, do a standard load work up process and it will work for you. Good shooting!!!!!

Add a little Tin and it will be spot-on. Actually, leave it the way it is and it will probably shoot just fine. CDD

Shoot them like they are. They will be just fine.
Hope this helps.

You're fine. I've yet to weigh a cast bullet. If it looks good, I load it.

You're complaining about 3 grains??¿ 
Just be thankful that's all the variation you're getting.
That's why we do load work-ups. To account for small variables in bullet weight, hardness. It won't amount to a hill of beans.

Yes, you are doing well to get a mould that close. Many are farther off than that, not even considering alloy variations. I ordered some 365 grain bullets for my .38-55 rifle and they came in at 374, and that out of a harder alloy than the mould was supposedly calibrated for.

Snuffy, I don't think he was complaining. Just asking. Learning.
That's what this place is for. Trading information so all of us can be better at what we do.
Flash Hole, Your RCBS mold was designed to drop a bullet at a specific weight based on a calculated amount/percentage of pure lead, Tin and Antimony.
Wheel weights don't have the same percentages of those compounds and might include a little zinc. Reloading at cast/target velocities, you can have a slightly heavier or lighter bullet and not know the difference. Variation in your bullet weights will affect point of impact/group size though. But I feel that you're asking about dangerous affects? None with a 3gn increase.

Dangerous
Thanks Steve,
You answered my question about the dangers.
I am thinking I need a signature. Maybe this.

Ah, but folk that say what they feel, sometimes don't think about what they really should or shouldn't say.
I get caught up in that once in a while.
