I am considering a 6mm/223 conversion for a Mini14 581 series. Anyone have experience with this using the Lyman 245496 Lovern? Or any other mold in the 85 gr range?

Interested in the Douglas barrel. IMHO...I'd opt for a 1-10 twist and definitely no slower than 1-12. The 1-12 twist is marginal with anything over 90 grains in the real world. Your velocities will limit you somewhat with the 1-12 twist too, again IMO.

Thanks

6mm-223 is simialr to my 6mm TCU. My gun does ok with the 245496 and appears to be promising. I have to work on my loads for it to get better accuracy. I've tried the heavier 245498 but the boolit doesn't really fit my bore so I gave up on it. Dismal accuracy is the nicest way I can think of to put it. What I've found out fairly recently is there aren't a lot of molds available for the 6mm of any weight. I have plans to get the RCBS mold eventually and am working on getting a custom mold but it is of a heavier weight. I am thinking Saeco has a 6mm mold that may be useable, depending on the nose diameter. Good luck with your quest.

P.S. You might want to consider the 6x47 as it has a longer neck. Being based on the 222 Mag though, it may be too long for your application. Just a thought.

I have a 6x45 (6/223) on a Rem short action with a 1/10" twist.
I shoot both the Lyman Luverin and the RCBS and both shoot very well in my rifle.
In a mini 14 OAL would be an issue with the RCBS. The Lyman Luverin should be good to go in the mini in reguards to OAL.

I have a couple copies of that mould and it is a good one. Either 12.5 grains of 2400 or 18 grains of 4198 is the load I use. I also have the Saeco 85 grain mould and that's another good one. The king of them all has to be the RCBS 95 grain one. It really shoots!
