Bore Capacity can only be increased so much by added bll length >> to a point. In converse, a larger bore is less susceptible to velocity loss in
shorter lengths. HELP Denton <grin>
So, if you follow me, the 6.5 or even 7-08 will fair well in shorter barrel lengths.
Good Luck

Thinking the operative phrase is "expansion ratio".
Sorry Dan, but it is Bore Capacity. I have Denton's equation to figure it.
Bore Capacity = Bore Squared / 1000. ***edit << -- Bore Dia.*** Squared/1000
The problem w/JR40s comparison is the 06 & 308 use the SAME bore dia.
Smaller bores have LESS capacity than larger bores. ( duh
really)
If you run comparisons 308 - 708 - 243, using the same CASE size you'll find the 'smaller' bores
Lose MORE vel (speed) in SHORT blls.
Casey (alpinecrick) verified what I suspected per the 708. That's one cartridge I've never had but I've experienced the diff in bore capacity using
358/308/243 enuff to have predicted the 708 would do well.
To All: I have no horse in this race.
