Reamer advice please

[Justice1327]

I am having two reamers built. Please see attached photos.
I personally am thinking about increasing the free bore, but I'm not sure how much and if it is necessary at all.
I did send in two dummy rounds each with a different bullet and Ray chose the listed free bore as best compromise.
Additionally, if you see anything else that you recommend, let me know.

Ray has helped me with several reamers and his dimensions have been spot on.

 

[Justice1327]

That is good to hear. Thanks

What brass are you planning to run?

The 6.5 Swede .299" neck is why I am asking. I have a couple 6.5mm reamers, and I run a .297 or .298. The .299 will give you room for a no-turn for any case I can think of.

Ray knows his stuff and is super helpful…I'm not going against anything he suggests.

Lapua only in the 6.5x55.
PPU and white box winchester for the 7x57.

One thing that surprised me was the 6.5x55 has slightly more case capacity.

Yeah, it is an AI. You gain some good numbers by doing that.

It will be similar to this (this is a .260AI, not 6.5x55AI) but you get the idea.

Yes, I should have been more clear: I was surprised that the 6.5 x 55 AI had more case capacity than the 7 x 57 AI

Yep, looks good!
I like my .243 & .260 & 7-08AIs
