Hello guys,

I tested my wheel weights made bullets for 30-30 with some IMR4198. My best result was with 25.5 gr. The bullets are gaschecked.

Can someone tell me what velocity they were shooting at.
My 336 is microgrooved with a 20" barrel.

Thank you.
Cheers,

Mad

Mad,

I looked in Lee , Lyman's Cast, and Speer manuals and got nothing for either 120gr cast OR IMR 4198. Best I could give you would be an uninformed guess. I really think your best bet would be an inexpensive Chrony. I got mine without frills for about $75 new.

Sorry :oops:

I do hope someone can give a close ball park. We all know that same components give different results on a per gun basis.

Mad Russian, you might want to check out those cast boolit guys if you haven't already. There is a ton of good information there and you might find someone who has chrono'd that same or very similar combo.
