Trueblue Wrote:Thanks for posting this. Putting together a 16 build at present. Not seeing much advantage to going to 20-24 after looking at this chart. If I need to reach out past 350 yards, I would use my 6.5 SAUM or 7-300 WM.
All those numbers change pretty noticeably for me up at altitude, and I could have used best-case scenario with the highest BC bullets possible, like the 123gr SMK, 123gr Scenar, 130gr Bergers, and 130gr Nosler RDF.
The 18-24" Grendels make a lot of sense for people who want to shoot more LR from 600-1000yds down at sea level in constant wind conditions.
Even with 6.5CM or .260 in shifting winds, getting predictable hits on-target at 1000yds is very hard, even on full-sized silhouettes.
Conditions have and always will determine practical effective range for that time window you shoot in. Higher BC with more speed will extend your effective supersonic reach some, but often that comes back a bit from 1k when wind gets dicey. 6.5 SAUM or 7mm WSM can extend that effective range noticeably for sure.
