I finally scored a box of 80 gr Barnes TTSX bullets. Could someone who has a box of factory loaded .240 ammo with the 80 gr Barnes please measure the OAL.  With only 50 bullets it doesn't leave a lot of room for load development.  Thanks.

I've always found Barnes recommended length to work for me. Their book says 3.100" .  :)

Thanks , Norma 100 gr group Ok but 100 gr partitions string vertically 2 to 2 1/2 in. Running out of time for deer season. I may have to go with the Norma loads.

Never had Partitons give me that problem until I changed powders!  It is one of my go to bullets along with Barnes and A-Frames. Perfect short range hog killers! No velocity break ups and good at longer shots as well.  :)

I haven't removed the action from the stock yet but I may do that and retorque the action screws just to make sure everything is kosher.

This is the vertical stringing I'm getting with factory 100 gr Partitions.  If the vertical matched the horizontal I'd have 1/2 in groups.

did you change scope settings in between groups?? If you didn't and overlapped the two, the 6 shot group would be over 5 MOA. After you check the rifle over, and it still does that, then it really don't like that load.  :o

What powders do you have to try?? After shooting up 3 boxes of the 80 gr ttsx, I gave up trying to find a load for them for my 240's, for now.  Didn't find nothing I like. But the powder's in the 4350-4831 range seem to show some better results than the slower ones, then I ran out of bullets to keep going.

Didn't touch the scope.  Never do when testing loads.  Powders on hand include:

Hodgdon: 4895, 1000, Benchmark, CFE 223, Retumbo, 414, BL-C2, Varget, 380, 4831 SC, 335, 4198.   IMR: 4064, 4198, 3031, 4831, 4350, 4895, 7828, 7828 SSC.   Reloader: 7, 15, 16, 19, 22, 23, 25.   Norma 201, MRP, MRP-2.  Viht. N160. Accurate LT-32.

Started to pull the action from the stock. Checked before hand, rear screw was 35-37 in lb. Front screw unk. Extremely tight.  Will call WBy tomorrow about it.

I would start with either h4831sc or rl19 frist, and just a standard rifle primer.

Removed the action from the stock.  Front action screw torqued to approx 55 in lb, rear screw to aprox 35 in lb. thread locker on front screw. Will reassemble with proper torque values (55 in lb) front and rear. I'll put together some loads with the 80 gr Barnes and see how they do.

Unless I missed it, you didnít mention which powder youíre using. I load for 3 different 240s. All work great with RL22. Shooting Nosler 90 grain Accubond and 95 Ballistic Tip though. Scary accuracy. Donít know about the TTSX. Iíd start with 54 grains of RL22 if I was using the 80gr TTSX. I know itís blasphemy on this site but Iím not enamored with Barnes bullets. Had better luck with Nosler. Others have other opinions.

Good luck.

both my 240's like RL22 with the 95-100 bullets, and I have a feeling RL23 will work very nicely with the 95-100 bullets also. But the loads I tried so far with RL22 and the 80 gr ttsx where not that good, in my rifles. I talked to a guy I sold a 240 to a few years back, and he's shooting the 80 gr ttsx in it. He says his best load was with IMR4831. The problem is with if you only have 50 bullets to work with right now, you really just have to pick one powder to try, and hope something decent comes from it.

Mine shoots fantastic with the 85gr Sierra BTHP over IMR4831.  No joy with that powder and the 100gr Sierra BTSP.  If I was going to try the 80 TTSX, IMR4831 would be my first choice.  I just got my second 240 and plan to try 100gr Partitions in it.  I'll try RL22 or RL26 with them.

      My go to load with 80-85gr Barnes in the 240 is 52gr IMR 4831 with a Federal 215 primer. A Rem 9 1/2M will also work. I am using a 6 lug MKV and I seat to a COAL of 3.350".
