Anyone tried one out yet?

Yeah, I know blued only which kinda sucks, but it does have the 1-8 twist.

Thinking of getting one for a backup or loner rifle.

Thoughts?

Thanks

Ruger AR or Vanquard in Creedmoor - 8 twist - better rifles IMO for $$.

Did any even get released? Seems like they would have started trickling out just about the time the XMP recall hit...

Bud's has em in stock for around $550. bear in mind that the 700 is a much more upgradeable platform than the RAR ...

I wondered the same and talked with a dealer yesterday. He said his supplier had 10, 260's in stock at the moment. He also said the trigger issue should be taken care of by now since they did not get sent to dealers yet.

Web page sez it's spun 1/8, so it should be a good setup with a lot of options to customize....

Lots of options to customize 700s, that begs a whole other question....

The only reason for the 1/8 twist is to shoot the 140 VLD of which they are to long to fit in the sa Rem magazine. Rem should have chambered it in the 6.5 Ceed.

My 1/8 twist shoots both the 123s and 130s about .050 in BC higher than a buddies 1/9 6.5x47.... same velocity, same bullets... but mine go through the air better. Just an observation....

My 700 sa 1/9 in 260 ackley shoots 130 VLDs. .5 @ 200 yds.

SU35 - +1 on CM. Is your AI an OEM or custom tube? What brass/powder? Suspect Lapua/H4350.

Not talking about accuracy... I'm talking about stability and it's effect on observed BCs.
Posted By: 65BR Re: Rem SPS in 260? - 07/17/14
Saying BC is .5 at 200 yds? I got the spin vs BC correlation, but thought the .5/200 was group size.
Posted By: Dogshooter Re: Rem SPS in 260? - 07/17/14
I can see the confusion...

I'm saying 1-8" shoots the same 123 grain bullets (Amax and Scenar) bullet .050 points HIGHER BC on average. The 1-8 twist seems to get a little more BC (.530-.560) than the 1-9" twist (.470-.520). The velocities are equal at the muzzle, as was general group size... and all atmospheric conditions were the same.

Not scientific, but I'm convinced there's stable, and there's STABLE... and I think it matters. The 1-8" helps eek every last bit of good outta the midsize 6.5s.

I'm thinking your scope height is the factor, not faster twist.

65BR.....I'm using Lapua brass and burning 49 grains of Superformance for 3,000 mv. Factory tube punched out on Ti 700.

Bryan Litz agrees with you:

Talley lows on both.... it's the twist having an effect on BC. There's no other explanation...

John.... I knew Litz agrees... I wasn't gonna bring that up though..... just reporting what I've seen personally. I also remember an old article in RifleShooter Mag, that showed an increase in BC with 10-15 different projectiles as twist rate went from standard 1-12" to 1-9" in a .22-250. In fact, the 50 grain bullets improved with added twist.... even though they're surely "stable" in a 1-12".

A 1-9" twist will spin a bullet 235,000 RPM at 2950fps.... the 1-8" will spin same bullet at 265,500 RPM.... That extra 30,000+ RPM ain't hurting the stability.

I've noticed the same thing shooting the .243 105 HPBTs out of the 1-10" vs. the 1-9".... a 1-10" "stabilizes" them.... but a 1-9" shoots them better, and with a noticeably higher BC (about +.025-.035).

Very interesting...
Posted By: Dogshooter Re: Rem SPS in 260? - 07/17/14
Just got a call from my brother... a load that shot the 105s outta two .243s in the sub-MOA range out to 600 here in CO.... just went tits-up the first time out in CA.... Keyholes galore...

Stable ain't always stable....

Density altitude matters� Thinking with the quality of bullets nowadays, it'd be hard to spin one too fast.

Good stuff, I always felt decades ago that the 6.5s may well kill better than most would imagine b/c fast ROT keeps the bullet nose fwd which ensures better straight line penetration thru vitals/POA. As a side benefit, debated often, faster ROT may add to the damage a bullet does in tissue. Something I seen illustrated in a test written up in a Handloaders digest from the 60s/70s. A 7.7" Mil-Surp Swede vs a 6.5 RM 600, using 129s and 125s shot into newspaper. The quicker twisted Swede had MORE bullet upset and a wider wound channel, albeit slower mv than the 6.5 RM. Read other similar reports over the years, perhaps some trught so it seems. None the less, I ALWAYS choose the 8 twist in 6 and 6.5s, and always prefer leaning on the faster side in any rifle, when given a choice. I don't shoot BR, where a smidgen of group size might go to the twist that is "Just enough" as that is meaningless in the field when bullets hit game IMHO. To me, MORE is better when it comes to twist rates, shy of jacket ripping RPMS. True I suspect a faster twist fouls a little more and causes more friction which can slow potential MV to a minor degree, neither are enough to worry me.

P.O. Ackley claimed that the 220 swift killed all out of proportion to it's caliber, due in his opinion to the fast bullet spin (in this case from the high muzzle velocity resulting in faster bullet spin).
