6.5 x 47 Lapua recommended reamer freebore for 140 and 130 Hybrid bullets?

On a 6.5 x 47 Lapua, what is the recommended reamer freebore for 140 and 130 Breger Hybrid bullets? And the recommended reamer neck diameter for no turn brass. A reamer print number would be appreciated if available.
 
Don't know if you can compare the bullet prints as I am not using the hybrids, just the 130 VLDs. My neck diameter is .294. Freebore is .140
 
Thumper,
Take a look at JGS print # 2124. It has a .293" neck with a .163" freebore. It is what Kelbly's used to chamber my tight, no turn hunting rifle, works well with the hybrids, through an extended length magazine and I am very pleased with it. If you're not concerned with a magazine and want all the powder capacity you can get, you may want a longer freebore. By the way, according to what I've read on this forum, it seems that most prefer to jump the hybrids but my rifles shoot very good with them seated well into the lands.
 
Ram,

I'll have to check that for sure when I get back to the house. I have my comparator dimension in my head but don't remember COAL. I seat well into the lands and want to say it's about 2.850" give or take but I'll check and let you know.
 
Long freebores work great with the 140's I use a .290 neck and .220 freebore with the hybrid into the lands, they have always needed to be jammed to shoot good for me.
 
Ram,

I measured 8 loaded cartidges that I had handy. Although the head to ogive dimension was within less than .001" the COAL varied .008". I would say they averaged 2.845" COAL, which is about .014" into the lands on this particular rifle which has had just under 150 rounds down the pipe.
 
I have learned only to trust JGS numbers. I have had too many others with freebores way off. A 140 vld COAL is 2.8" in a .180 freebore. I would not go less than .160.
 
Mine is cambered with the one grizzly has in stock (Neck Diameter: .295-.2944
Freebore Length: 0.1670) and shoots the 130 hybrids quite well.
