Nope.
Several reasons.
Lapua 77 Scenars have had a BC of over .410 this whole time.And loads exist that will get them to 2850.
75 VLDs have a .420 BC and can be pushed to 2950 fps and are being used right now by a team,at that speed. Short bearing surface and loaded long, NO problems.
Berger 80.5 full bore have a BC of .454 and I have a load with MR2000 that pushes them 2875 in a service rifle.......
so..... Nope, not at all.
1/2 a min isn't that much. The 75 VLD would be a min or more over your 80.... that's worth it. 24.0-24.5 gr8. H4895 jump.them .030-.040.
