"Best" 6-6.5x47 Lapua Reamer and Why??

[SHootSTraight22]

Guys, who all has experience with different 6mm Lapua reamers and what was your experience... I'm talking most importantly FB length for 105gr class bullets, plus being able to hit max velocity... What has trial and error taught you about this cartridge... It was stated to me by a well known gunsmith that all I wanted was a .100FB to achieve 3,150fps with around 39.8-41gr H4350 and 105gr hybrids... He said "no" to all other freebores...

When I built my 6x47 lapua I was told I needed a .130 freebore to shoot the 105gr hybrids. But... I chambered it with a .098 freebore and currently shoot 105gr hybrids at 3050fps out of a 28" 1-8 brux with nice results.
Load is 39.4gr of h4350 without pressure issues.

Around .100" +/- a few is right where you want to be for the 105 class bullets.

Great thanks!! What I'm confused about and can't seem to get any answer on is then "why does Team Gap use a .189FB with it's 6mm Creed??? The 6Creed, 6SLR, and 6Lapua basically have the same shoulder/neck so wouldn't it make sense that each of these cartridges could benefit from the same freebore??? Why are they having to use that freebore length to acheive 3,150 in a 6Creed?? From what George stated the freebore length and .237bore is the most important for 3,150 and long case life... Does anyone know or have an idea???

Why don't you just ask George.
