wtm 45: IIRC, when the 264 & then 7 RM came out the bullet diameter had more influence BECAUSE there were several MORE bullet weights and better bc & sd in 7mm than 6.5 (264).
Sometimes my memory has dark holes or cobwebbs, or rust but I'm pretty sure on this one.
The 264 has LIGHTER bullets but the 7 HAD & does have more heavy bullets. Back up to the 60s & 70s, we didn't have monos or bonded LIGHT bullets THEREFORE the heavy bullets had more APPEAL and practical applications than LIGHT bullets.
Today the monos or bonded bullets SURELY helps the 264 but the discussion IS about why the 7mm out sold and became more popular.
That's the way I understand it and I'm NOT anti 264 but even today I prefer the 7mm and I have NOT hunted a 7mm in at least 4 years.
Now back to the 338F vs 7RM, IF faced with ANY dangerous game I would PREFER the 338 WINCHESTER MAGNUM or larger cartridge.
