105 Amax is .500 and the Berger VLD is 0.532. I don't think the 1:10 version would be that slippery (considering the 1:8 should be better) to be around .500. I would think the .460 is more like it, but as you say proof via chronograph will fix the problem.

Hi Fellas, just notices this. I make two 105gr bullets one on a 1.050" jacket with a 10S ogive which makes a bullet to stabilize in 1 in 10" twist barrels which has a BC of .460 & another made on a 1.150" jacket with a low drag design with a BC of .500 which requires a 1 in 8" twist.
I also make a 112gr on the 1.150" jacket in the low drag profile which will work in 1 in 8" twist which has a BC of .520.
The BC's on these were tested & given to me by the late Tony Halberg (one of the makers of millenium actions etc..)
Hope this clears up the confusion.
Cheers, Bryn.

The 95gr LD bullet mentioned has a BC of .450
Reason I make the shorter 105gr bullet is solely to provide a heavier bullet which will work in the 1 in 10" twist barrels which most factory 243's have.

I used .450 as Bryn says for the 95 and it got me close enough with logging to hit things.

Thanks Bryn and others. I will use .460 and see what happens
