6.5CM 18in 147Gr MV

[Lunar95]

I'm converting my AR10 into a 6.5CM.

Going to put an 18in barrel with a TBAC 7Ultra Can firing 147gr ELDs

Anyone have experience with 18in barrels and the heavier grain ammo? Or should I of went with the 20in barrel? (criterion)

I cant find any MV charts for 147 ELDs

Goal is mostly sub 1k shots as my tikka with be doing anything past that. Id also like if both used same ammo.

Factory 147s were 2530ish from my 18” PVA/Rock Creek...only 15-20fps slower than factory 140s.
