Lee c309 170 f and a 3030?

[Elbow]

Any experience with these boolits sized to .308 in a 3030?

I use that boolit in several .30 caliber rifles, including three 30/30's, but I size them to .310".

Elbow,
Many folks have good luck with that bullet in a 30-30, but probably not sized to .308". You didn't say what kind of 30-30 you have. Most will prefer a bullet sized at least .309", and usually .310" to .311". I'm sorry I can't direct you to a specific thread, but there there are several here dealing with the same or similar bullets. Search the site and read a few threads on the subject. You'll be able to answer your questions as well as some questions you didn't even know you had. :grin: I'm sure others will come along with some tips soon.
Good luck,
Rick

My Lee 170 fp drops around .310. Many years ago before I knew better I shot them sized .308. I tumble lubed, sized and gas checked them through a Lee sizer. I decided to test them against the same boolits run through my .311 sizer. The larger diameter was clearly more accurate. I didn't get leading from the .308 diameter thanks to the gas check. Now, thanks to this site, I have a more clear understanding of why the .310 diameter is better.
