I get an even (and very easy) 2700 with H4831 and 130 grain Accubonds from my Sako with Lapua brass. I'm sure I could easily get another 100 fps or more but it shoots bugholes as it is and has killed deer very neatly out to 400 yards so why bother. I've no doubt I could get 2700 or more out of 140's. Next bullet I'm going to try is the 130 grain Sierra HPBT GK.

Don't have my 6.5 X 55 Sako any more, but it loved the 140 NP at 2700 (MOA) on the nose over RL-22. In also shot the (former) 120 BT at 2900+ into sub-moa using the same powder. Never saw a need for anything else in that rifle (22"). Bob www.bigbores.ca

I followed John's advice and added two more grains of H4831sc. I went up to 49gn for 2648 fps in a 22" barrel. Accuracy is about 1 3/4 inches though. I thought the groups might shrink a bit by upping the velocity but maybe my rifle just doesn't like these bullets (140gn Speer SP). The 120gn Sierra SP will go under an inch.

I've shot some big game with 140 Speer Hot-Cors from a .264 Winchester Magnum, but accuracy varied considerably from lot to lot. I found when using a Juenke Internal Bullet Concentricity Comparator that in some lots there were quite a few poorly-balanced bullets. If I culled those, the well-balanced bullets shot quite well. But without the Comparator it's impossible to tell which bullets are well-balanced, and the faster you push the poorly balanced bullets, the worse they shoot.
My bet, based on some experience, is that if you tried Hornady Interlocks or Sierra GameKing 140's they'd shoot pretty well at 2650, or even faster. In fact I'd bet 140 Nosler Partitions would, because in recent years they've been among the most accurate bullets in several of my 6.5's. But Partitions would probably be a bit pricey for your purposes.

For what it is worth, I found the most accurate 140 grain bullet in ALL of my 6.5 bore rifles was the Remington Corelokt... surprised the heck out of me, that' how it has turned out...
I was lucky... before Obama got elected, I bought like 1500 of them for less than $80 delivered to my doorstep...
Same period got a 1000 6mm 100 grain Corelokts delivered for $100.00....
wish I'd have bought a lot more stuff then....

H4831 and Hornady 140 gr. interlocks have been a very accurate combo in my M38 swede.

I have 129gn Hornady Interlocks and SSTs as well as Ballistic Tips in all three weights. The Hornady Interlocks have shot good in a bunch of my rifles. The Speers will get used on pigs in the scrub at fairly close range.

Elvis,
Ah! Then you don't need super-fine accuracy with them anyway.

I use H4350 or RL19 in my 22 inch Ruger M77. Either one of these will get 2750 to 2800 with 140 grain bullets.
