Thread: Short Barrelled 6.5x47 or 260?

Might as well have a 30 then working on that theory.

Explain how "a 140gr Amax has a much higher BC than a 100gr Barnes and at the speeds above the Amax is going faster at about 220 meters" means that you might as well have a .30?

You can't get close to the bc of a 6.5 projectile with a .30 cal projectile of similar weight. It's a long range thing.

I meant three O

gimp, if your that set on BC why wouldn't you go for Hornady Manufacturing Company :: Bullets :: Rifle :: Choose by Caliber :: .264 6.5mm :: 6.5mm .264 120 gr A-MAX® that near to the same BC but you can get is steaming along, unlike the 140.

Apple lemon comparing those others when you in fact can compare the same at different weights.

Then a better choice yet could be Hornady Manufacturing Company :: Bullets :: Rifle :: Choose by Caliber :: .264 6.5mm :: 6.5mm .264 123 gr A-MAX® (Grendel/LBC/Lapua) as it tips the .5 BC (well so they reckon) atnd would be doing same speeds as the 120.

Because the 140 is still better at long range, has more energy too

Yep & the further you go the bigger the difference, IMHO more than ballistic tables suggest as well....

What do you mean by that?

We are talking about an 18-20" barrel. Not a long range rig.

Would you honestly go grab a bush slut to shoot at long range?

I use my 20" barrelled 6.5x47 to do just that, so, yes

And given that it works quite well, how am I hobbling it by using a 140gr and in exactly what quantifiable way would it be improved by using a lighter bullet?

Ages ago I was shooting Ashlees 260, 140 Amax at 2930ish against a very accurate 6.5-47 with 123 Amax at 3000-3050 ish ???? (long barrel)

The 260 connected several times at 1280 yards the 6.5-47 not so much, if at all same conditions, I had 4.5moa for wind IIRC.

There is no reason why the 6.5 couldn't do it, it managed at 1100, I guess it just run out of steam with the light pill ???

I have noticed the same thing at extreme range with other rigs.

Bad shooter? (It reads like there was someone else shooting the other gun)


Also the 123 gr BCs haven't been tested by Litz last time I checked and I've seen them reported to be over estimated by Hornady so the 140, which already has an advantage, may be mo' betta. Also your .260 140gr load is super fast.

Yep not me shooting the 6.5-47 as good or better shooter than me

Ashlees 260 has a 26" barrel & good component choices, very accurate

Makes my .260AI in a 24" barrel using good components, so far only getting 30-40fps more with the same projectile, look like a waste of time. Although I havent finished load development yet. Seems fast for a standard.

I think what you're referring to Greg is a compounding effect of pushing a sub-par bullet too far in sub-optimal conditions... No?

Its a long term plan this but I would be bloody happy with 2700fps from a 20" barrel and 140gr Amax's. Chances look good...

Has always shot very well, 139 Scenars-140 Amax at 2930-2960 is the norm.

I'm looking forward to building a 260ai to see how it will go
