Does anyone have suggestions for a powder to try with this and the 160gr Accubond? Was thinking of Retumbo or US869.

Thanks for the reply. What rifle are you shooting, and what would be a starting charge weight for that load?
I've had some of my best accuracy luck with H1000, regardless of weight. It can be a little slow with the light bullets. Retumbo will give you the speed, but may be lacking in the accuracy end. One barrel I had loved it, 3 hated it.
444; My rifle is a Rem. 700 built by Ted Gaillard 26 inch bbl. I think 80grs. would be a very safe starting point.This is the one cartridge that I have used where using anything other then a premium bullet ,will result in lesser bullets coming apart like a grenade.

Yeah, I am sticking to premium bullets for sure. Same holds true for rounds like the .257 Weatherby.
Luckily I have some RL25 and just need some bullets to get started. Do you prefer the 140gr over the 160gr?
I had a complete failure of a Nosler Partition with this caliber, 160 gr. 3100 fps about 180 yards into a medium bull moose. Shed the nose in the first 4 " then went through like a fmj. I stick with X bullets with that caliber.

444,Regarding bullet weight I like the 140,s they fit the slot that I use this rifle for which is trophy Whitetails in farm land.When zeroed at 300m. the rifle is 6" low at 385m. and 22" low at 500m.For me the 140s are the right choice.If a close range shot is offered the TSX,s will plow right through.This past season the two Bucks I shot with rifle ,were both around 100m. away and were sharply angled raking body shots ,complete pass throughs.
I use RL25 with this bullet weight in my 7 STW. - dan
Did the moose die?
That's pretty much what a Partition is supposed to do, shed weight like a soft bullet and still have half of it hold together. Having said that I still shoot a lot more TSXs than Partitions, mostly because they shoot so well. Far too much is made of what a used bullet weighs, or looks like, mostly because advertisers have done such a good job of selling us. The bought and paid for boot licking gunwriters say whatever they are paid to say.
I'm shooting 140 grain TSXs over H4831 in my current STW, but have a good accubond load to try this fall.
I shoot 140 gr TSX over 84.0 gr of H1000 at 3460 ft/sec and 160 TSX over 90 grn of H870 at 3300ft/sec This is out off Gaillard build gun ....
Same loads in Sako 75 SS are not as accurate and velocities are 200 lower...
I would recommend to start with Tipped TSX as they will open faster at short range and have higher BC due to plastic tip.
I shot MRX bullet in 160 grain on antlerless elk at 60 yards and on frontal shoulder shot entry wound was 2 inches and exit on opposite last rib about 1.5 cm.
I think that TTSX will open faster in those circumstances based on performance of MRX which has same deldron blue tip.

Well, I have a few different powders to choose from (RL22, RL25, 7828SSC)
but maybe will try Retumbo and H1000 too.

Andrzej,
Mine is a Gaillard job as well. It's a natural to get him to install his own barrels, esp when he only lives an hour down the road. I used to use basically your load on my first STW, but with a 139 Hornady. Gawd that thing would flatten deer.

About the way a Nosler Partition is supposed to work. Obviously you recovered this animal. I have shot Partitions out of everything from the 6mm Remington up through the true hotshots: 264 Win Mag, 7mm STW, big 30's and the 338 Ultramag. Never had a "failure" as you describe it. Recovered about 20% of them,(I have about 22 recovered) the rest exited, usually leaving a fairly small exit. Did any game fail to die quickly? No!! I have driven the 6.5/140 Partition & the 7mm/160 to 3300, and the 6.5/125, 7mm140 to 3500, and nary a problem. TSX works fine as well, but will damage meat just as badly as any other bullet if big bone is hit, so whatever you prefer. Regards, Eagleye.
