Why so many 6.5mm 142 ABLRs for sale and 7mm hard to find?

[Roughrice]

Just wandering why so many 6.5mm 142 grain ABLRs are always for sale or available at most sites while 7mm's are always sold out or hard to find?
I use 7mm 150's and 168's but never tried the 6.5mm 142's.
Are they hard to develop loads with or poor terminal performance?

Let me know if you run across any 6.5mm 150 ABLR. I'd like to give those a try.

Because they always seem to leave a flier hanging out there...

168's shoot very well in my 280AI and SAUM and 150's very well in my 284 Win.
I've found they are more consistent with a good jump than too close.
