It's published on CO Wildlife and Parks website... And while I said it's a suggestion, it's a pretty good one. I've seen a bull take 4 shots of .308 to the vitals with a 168 TTSX at 400y (1600 ft lbs on impact) and keep going.
A 6 ARC isnt going to get the job done at 600y, neither is a 223...not with any reliability. If it does at 600y, it's pure luck.
And where did CO parks and wildlife get that info from… the know nothing gun “professional” writers
Like hairy said, you proved why impact ft lbs is irrelevant. If 1500 is the minimum, 1600 should’ve totally smoke em huh? Copper bullet in a 308 is an incredibly poor decision if one wants to actually quickly kill
I’ve personally shot a good number of elk myself and been a part of may other successful elk hunts. Most of which were shot 300-600 yards away, a few were about 100 yards. Most of those were with a 270win with 130SST, 150 partitions at the close shots and a 300WSM with 150 nosler BT. We were over gunned but shooting good, fragmenting bullets that resulted in decently fast kills. We got lucky back then and just happen to pick those bullets. However, the only one that got away was when a buddy was shooting a cow with a 338 win mag with some 200 grain bullet. Tracked for miles and never recovered
For a while now I have been shooting a 6.5cm with 147 ELDM/143 eldx and it works well. Considering going down to 243 with 108, even in the longer shots
Larger cartridges like 7mag,300mag, etc with the correct bullet type, are not bad. As long as it’s a good fragmenting bullet, some would agree it’s even better since it’s likely a larger bullet going faster (velocity dictates how a bullet fragments aka “mushroom”). But their down side is 99.9% of guys can’t shoot big magnums well and definitely can’t spot impacts/misses which can make follow shots a crap shoot if the first one missed and they didn’t see it
