Hey Blakey,
Apologies if its covered somewhere in thread or elsewhere but...What do you think about 6mm ARC vs 6.5 Grendel? Is there a clear winner?
are you any good at splitting c-hairs?
sd is good on 103-108's, impact velocities give 150-170 yard advantages, which are beyond where hunting occurs (beyond 500), you're under 120 grains of bullet weight...
basically like the 6.5 CM will get the nod for hunting over the 6 CM...apply exact same logic to the 6arc vs 6.5g, like all 6mms they tend to get the nod for more steel/paper/varmints but the 6.5g more for big game hunting
the 6arc is really just a 6 grendel, great cartridge choice if 6mm is what you like or if you want that extra distance for similar impact velocities
overall balance of all options is with the 6.5g, where the 6mm general trade off a couple of balance points to the negative to gain on a couple more on the positive...the 6.5g does not, it is the most balanced and well round option of all factors combined in choosing between both hunting, target, barrel life etc. etc.
also, read a comment even from a target guy who may not stretch as far as possible but prefers the audibles and visuals of the 6.5g 123's on steel (and misses spotting splashes) vs the lighter 6mm's much harder to spot for and harder to hear the impacts also...so there's that, and that guy is all about range time and mass volume shooting
you can't go wrong either way, they're both better option than .223's with 77gr tmk's imo
if you have 10 points of criteria, 2 of them will be higher marks and 2 of them will be lower marks than the norm with the 6mm, those same 10 points of criteria with the 6.5 will have an even line down the middle is what I mean by better balanced, more versatile, more efficient overall...6mm's have some trade offs in all the things we like to do here with our centerfires powder burners
6arc is the first off the self short fat 6 that runs with dasher/br/ppc performance levels though, which is pretty cool for those who like 6mms
I like it a lot, it's big game legal, it's got great efficiency and versatility, it can do nearly as much for the powder burned as a 6.5g overall...so close but splitting hairs really.
I'm sort of like that guy who prefers the 123's of the 6.5g for impact audibles and seeing miss splashes at the range....except in hunting, which is all I care about, I've just come to prefer bullets weighing 120 grains or more on my minimum end so all 6mms are out for me.
