Fotis, the std. .240 twist is 10 and you gotta be careful with long, sleek, heavier bullets. The link you posted suggested 8 twist.
IME, the 100 gr. NPT is about the max wt. a 10 twist will handle, 105's don't stabilize. Heavier monos, because of their length, would probably fall into that category. Partitions aren't that long and sleek.
Great round. I wish mine was an 8 twist. If I built a .240, it would be a 6-06 with 8 twist.

Yeah I think they require a 1 to 8 minimum

100gr Norma Oryx. I have some 95gr Partitions inbound

I had a Weatherby LW Accurmark and then a custom Model 700 in .240 Weatherby. Also had a custom Model 7 in 6mm/284. Shot 90 & 95gr bullets only. Well, I did load 50rds of 70X in the Accumark. Its a great killer and I have a friend/chuch member here that has used his Mark V in .240W with the Nosler 95PT over 40yrs, deer, elk. I didn't find the Weatherby brass hard to work with, just to find! The 6mm/284 was the same thing, but lots of case prep. I like it, always used R19 in mine. My friends uses 4895.

With regard to twist, I shoot a 6mm-06 built specifically to shoot the 105 Berger. I had planned on a 1:8 twist but my builder (Kirby Allen) convinced me to go with the 1:9. He found the 1:9 stabilizes well at 6mm-06 velocities so I took his advice. Easily sub 1/2 MOA with several groups in the .2s, .3s, and .4s before I stopped punching paper and switched to live critters and long range rocks. Light recoil, kills with authority, and great accuracy.
My 25" Bartlein will push the 105 at around 3400 with several powders. I found I got lower ES with RL23 and slowed them down to about 3300 as I simply don't need the extra FPS and thought I would help brass and barrel life at lower pressures.
A 95 berger with a 1:10 is a good option. I have seen them shoot in .243s at much lower speeds. I would personally take a hard look at an 85 TSX or 90 accubond if shooting a 1:10 .240 inside of 4-500 yards. You can get them screaming within ranges where BC won't make much difference.

I think I will be fine with the 95gr Partition.

I think I will be fine with the 95gr Partition. It will be perfect. I would start there. Also had great results with the 95 grain Hornady SST. Used it in 243 and 6mm Remington. I had it exit on big Boar hogs. It's a pretty tough bullet.

I had it exit on big Boar hogs. It's a pretty tough bullet. Be sure you have the newer, latest SST. The older ones didn't hold together that well and the .240 pushes them faster than the .243 or 6 Rem. Some of those older SST's can be velocity sensitive. Like NBT's, I quit using them after some bad experiences. I went back to NBT's after Nosler toughened them up. I haven't gotten back with SST's, but have heard they're now tougher, not too unlike the NBT's. DF

I used 150gr SSTs out of a 303 Brit on a deer last year. Shoulder at 117 yards. Punched all the way through with a reasonable exit hole indicating expansion, so it appears they have been toughened up. J

I have a M700 with a crooked throat in .270, thinking about making a .240 WM out of it. I'll probably ask for a 1 in 8" barrel, however. Have to contemplate who to do the work.

take a hard look at an 85 TSX or 90 accubond if shooting a 1:10 .240 inside of 4-500 yards. You can get them screaming within ranges where BC won't make much difference. I ran an 80 TTSX at 3,600 fps out of my .240. They say monos don't have a velocity ceiling; I'm not so sure. If you're running a mono with S.D. < .2, like the 80 TTSX, I think you can overshoot the runway, so to speak, on WT and similar game. It may be OK of smaller stuff. A doe I shot at arouind 100 yds. had a huge chunk of meat blasted from her chest wall, very little damage inside the chest cavity. It seems to me that this low S.D. bullet, driven that fast, didn't have enough momentum to carry all that energy into the chest cavity. The energy was dissipated too quickly. I'm attributing that to lack of momentum, Or maybe the lack of sufficient mass was overwhelmed by hyper velocity. Too much speed for that light bullet on that deer. Extremes of about anything can sometimes cause extreme results. The 85 TSX may not be as bad. I like tipped TSX in small caliber Barnes; they reportedly open more consistently. Bigger calibers, not that much of an issue. BTW, 80 TTSX S.D. is .194, the 85 TSX is .206. That's not a lot of difference. S.D. of .2 is just an arbatrary number, would like opinions on very fast, very light monos on WT sized game. The 80 TTSX at .243 speeds may be OK. I'll not use it again the the .240 on WT's.. It was/is very accurate. I'd run the 90 gr. NAB w/o hesitation. As posted before, my 240 does great with the 100 NPT and it has a 10 twist H.S. Precision barrel. DF

I've had very short turnaround time with Shilen barrels. My idea is to pick the smith and find out what barrel maker he prefers. His reputation is on the line as well as the barrel maker. And some makers back their products better than others. No one is more in tune with what's going on in that industry than the smith. DF

Just booked a hunt for Axis & hogs next may with my buddy Hatari. Going to the SOE ranches (Canyon Ranch) with Mike Stroff of Savage renown so I;m going to take this 240 with those 95gr Partitions.

My current 240 bee shoots 100 gr partitions at 3425 at. 51" at 100 yds. I am using reloader 26 powder.
