142 Accubond Long Range

[bigd7378]

looks like midsouth shooters supply and Natchezes show .264 142gr ABLR!! Not yet available but in their database. Anybody hear anything on these?

 

[Thebear_78]

Sound like it would be an excellent long range bullet

 

[JD338]

That will be a dandy.

If in fact it is correct we will need 1:8 minimum to run these. The 26 Nosler Rifles should cover that. Does not make sense for Nosler to itro a bullet that their custom rifles will not handle!

BTW I can not see it

Whoa, that sorta bullet could make some folks rebarrel their 264's...

Nosler's website now shows a 1 in 8 twist for the 260 and 6.5x284. Not too long ago they were 1 in 9. Interesting.

PRETTY MUCH! No way midsouth are waiting for shipment and we do not know about it here!

I'm pretty sure that these will result in a super light build in 6.5 SAUM! Should be able to push them in the 3100-3200 range out of my 26" heavy 6.5/7SAUM.

If the BC holds up, this will spank my 280 AI with a 150gr or 168 gr ABLR!

 

[sask boy]

If I read right that is one heck of a BC .711 :shock:! I think that I am going to be in that dog house real quick if I order a 6.5X284 or maybe the Nosler 26 :mrgreen: !
Decision, decisions 8).

Dang... My Creedmoor build is using a savage hunter max 1 barrel that is 1:8. Think I'll hunt down a box when they are available and see how they do.

That BC is an eye opener.

Been thinking about that one as well although I really like the 264 WM probably more. Either way the 142 gr ABLR is going to shoot flat.

Need to try those in my wife's 6.5x55 and my 260 Rem, both are 1 in 8 twists. I bet with it's short bearing surface 2800 fps might be doable at reasonable pressures, with the 129 gr ABLR I was able to get a bit over 2900 fps in the 260 Rem, about 70 fps faster than the 130 gr AccuBond where I had to stop with 1 gr less powder.

I was sorta thinking the same thing with my little 6.5 Swede as well. That would seem like a sweet do it all sorta bullet. Soft enough to expand from the slower speeds but man would it hold onto some energy..

I just ran some numbers using a Berger 140, just to see what may be possible..

Seems pretty good.. Need to run the ballistics, but man, that 142 ABLR could be really good in the smaller 6.5's if they have the mag space..

 

[Wyo7200]

Ever make your own bullet profile for QL? Mr. Fotis posted the bullets oal on a campfire forum... Wonder if he knows the bullet profile or if they would be the same as the 129's.

 

[Ridgerunner665]

I'd say....just adding the difference in length between the 129 and 142 to the bearing surface of the 129 would get you real close to the 142....based on looking at the 7mm bullets.

I'd also guess that using the Berger 140 for QL predictions is plenty close enough.
