When I started loading the H&H NBT's and accubonds were not out yet. I looked at the 260 and 300 partition and at the speeds I could move them. The 300's held more energy from the barrel out to 500 yards but recoil was increased condsiderably. Since I intended to use it on plainsgame to 300 yards not DG I settled on the 260's. Since then I tried the NBT's but mine liked the partitions more. I am looking forward to trying the accubonds. If you can run the numbers for accubonds at 2800fps I would be interested to see what they do out to 500. I have not seen the published BC for them yet.
I know the partition is like a flying brick but they group well.

The BC for the Accubonds is 473 that is why I am staying away from the partition they have such a low BC and that is to bad because I really like how they have preformed for me in other calibers but from what I have read the Accubonds work about the same they open a little faster but penitrait and hold there weight about the same as a partition. How fast are you shooting the 260 Partitions and what setup?

24" Mod 70 Safari. I had to go with wood on this one. (I did not intend to use it for long range)trigger at 3 lbs Bisonite bedding and recrowned. barrel takes copper like a sharp file but still hods moa or better on average .8
72.0 of R-15 at 2780 fps.
For DG big bears / cape at shorter range I would use a 300 partition. Can't wait to try Accubonds.
Any excuse to take it out is a good one.
Happy i have one, next project is a 338 RUM

One thing to remember is that in the Ackley chamber you can still shoot 375 H-H factory rounds.The velocity suffers about 100 fps when doing this due to the case expansion.
On the other question of the muzzle brake i would follow your gunsmith and put one on anything bigger than a 280 improved in a gun under 17 pounds.I don't see heavy recoil aiding in anyway so why have it.

Lynn I am going with a standard 375 H&H with a longer tube of 28 inches. I figure with that length I will get the speed I am looking for and I will not have a muzzle brake I shot 300gr full bore loads this weekend out of my dads 375 H&H recoil is not a problem and that rifle weighs about 10lbs with a scope.
