.260 Remington?

[mg4201]

I am going to go a little off topic here

But where are you guys getting your brass and / or loaded rounds. That is the only small thing that bugs me about getting a 260 I want to build a heavy barrel in this cartridge for "sniper" shoots. I am a big recoil pussy so think the 260 will be a benefit to me.

Hirsch Precision (Peter Dobson) has .260 Lapua brass in stock.

3200fps with 300 mag and 190 gr is nearly impossible without pressure signs and DANGER... JP.

It proves that the 260 Remington with a 140gr bullet matches a 300 Win Mag with a 190gr in trajectory and wind drift out to 1000 yards. This has been mentioned and explained a few times in this thread already.

Sure we could compare the 260 to the 264 Win Mag if you'd like. Any time you push the same bullet faster, you'll make it shoot flatter and drift less in the wind. This higher velocity comes at the expense of more recoil, longer & heavier rifles (all things equal), shorter barrel life and less accuracy. There's a reason why long range competition shooters choose the 260 Remington or 6.5 Creedmoor or 6.5x55 or 6.5-284 Win over the 264 Win Mag or 6.5 STW

Nosler manual shows the highest velocity load with the 264 Win Mag & 130gr Accubond to be 3166 fps with RL22. For the 260 Remington, 2911 fps with AA3100. That 250 fps advantage would yield 3.5" less drop than a 260 @ 400 yards when both cartridges are zero'd @ 200 yards.

I don't know about you, but my crosshairs probably wiggle 3.5" at 400 yards from a steady field position. I probably couldn't take advantage of that extra velocity

What I can take advantage of is the lightweight compact rifles the 260 is often chambered in, which come to the shoulder quickly for those common hunting shots in the 50-200 yard range

Careful with the "less accuracy" statement on the 260 vs. 264, there are a lot of variables involved the least of which is certainly not the rifle and shooter. Are you suggesting the same for the 260 vs 300? The 300 is used in many long range competitions and I'd wager a bet more use it than a 260.

Let's start a thread comparing a 30-06 to a 375 Ruger, they're ballistic twins.

I ahve a lot of experience with 260 and 6.5x55. they get about the same results because the 260 runs at higher pressures.

In a modern rifle, you can add 10,000 psi to the 6.5x55.

I now change the 260 to an Ackley Improved. This gives it the same case capacity as the Swede. In my target rifle I get 2900 fps with 140 gr bullets.

And your target rifle is a .260 Rem, or a 6.5x55, or a .260 AI?
Just need a little clarification is all.

All things being equal (rifle quality, shooter ability, consistent ammo) the average 260 will outshoot a 264wm for group size. A 300wm is less overbore than the 264wm and usually overbore cartridges will not be as accurate as a smaller case/bullet ratio. No doubt a good 264 will give more than enough accuracy for hunting situations but we're splitting hairs here

The 300wm is much more popular than the 260 for target shooting, but alot of that is probably due to rifle and ammunition availability and selection.

....and then we throw a caliber like the 220 Swift into the equation and the inherent accuracy/overbore theory goes out the window.

I guess the 308 Win has the 260 beat in accuracy at about the same ratio as the 300 WinMag has the 264 beat then.

 

[todbartell]

I'm sure the average 223 will outshoot the 220 Swift, just like a 222 will often outshoot 223's at moderate ranges in calm winds

The 308 may shoot tighter groups at moderate ranges than a 260 too, but it drifts and drops so much more than a 260 past 400 yards it starts to get ridiculous.

OK then, carry on.

 

[todbartell]

If you believe overbore cartridges to group tighter, that's great. I wont stop you from thinking that, but I'd hate for someone on CGN who wanted to buy a 260 be steered away from it because of some misinformation

Well it's a good thing we have you to spread the truth.

Absolutely....Most hunters don't understand ballistics enough to even know the difference though.

 

[diemaco]

Absolutely....Most hunters don't understand ballistics enough to even know the difference though.

Probably because most hunters don't shoot far enough to see the difference. Lets be honest, within 250 yards, most modern "high intensity" cartridges are pretty close in trajectory.

 

[Gatehouse]

Within 250 yards with a good bullet, I'd use a .260 or anything bigger on any non dangerous game in north america....And I'd aim dead on.

absolutely true and inside 250 there is no advantage of extreme high velocity and only disadvantages. 2500 fps gets you to 250y with ease, +2" @ 100y and -5" @ 250y. The 6.5x55 has a very solid reputation as a hunting cartridge with these ballistics

 

[mg4201]

ok i'll bite what is overbore?

more importantly is it important to me as a shooter who is no threat to win a big match? just curious cause learning is fun.

A very big case with subsequent high powder capacity pushing a relatively small diameter bullet is generally referred to as overbore. There is no real standard as to when a cartridge is considered overbore. Calibers like the 7mm Rem Ultra Mag, 257 Weatherby, 25-06, 30-378 weatherby are among those considered overbore, just for example.

It is no threat to the average hunter. Even the most extreme overbore calibers, like the Lazzeroni's, can withstand 1000+ rounds or so with proper maintenance before accuracy drops off significantly. This would mean keeping the bore clean and letting the bbl. cool between shots.

IYAM, I think a mild, pleasant to shoot cartridge with great ballistics is much neater than those big nasty magnums that give you sore shoulders and sore ears. One could practice a lot more at long ranges with it.

I'm surprised the .260 Rem isn't more popular, given the praises sung for the Swede.

 

[AlexF]

270 is a better hunting round and had 50+ years headstart

The 6.5s are not popular because, for hunting purposes which is 95% of the market, 270s do everything 6.5s do only better and it cornered the market starting in 1925, way before anyone heard of 6.5 in North America.
By the same token, 303 British never was really popular in the US because they already had Garands, Springfields and 30-06 when they first got 303 rifles.

260 Remington is probably the 257 Roberts of the 2000s,
