Anybody shooting this combo, I was trying to work up a load tonight and accuracy wasn't that great but I found the scope might be at fault, I swapped out the scope and will try again tomorrow. I tried RL22 and H4831SC, does anyone have any pet loads for this cartridge and bullet in case the scope doesn't solve the issue and I need to pick up a different powder and start development over again?
 
You might want to confirm the twist rate in your rifle - especially if it is an early Mk. V. Those 115gr TSX are long and need a fairly fast twist rate.
 
If your load doesn't work consider going down to the 100 grainer instead of swapping powders around. TSXs don't need the weight, and the .257 'Bee is all about the speed anyway.

If you do try 100s, a load that has been very good to my son and I is 69 grains of IMR4831 and either the 100 grain TSX or Ballistic Tip. Its shot well in 3 .257s so far. The H4831 and RL22 that you already have are definite contenders. So is IMR7828.
 
It's a factory Remington, I would really like to stay with the 115's if I can get them to shoot, hopefully I will shoot it again tonight.
 
If that dosent work out for you try a 110 grain accubond with 70 grains of IMR7828 and a federal 215 primer. 3 shot groups go just under an inch in my rifle and average 3487 feet per second. COAL is 3.250
 
Thanks guys, I swapped out the scope, scrubbed the bore and loaded some rounds up with a stout load of RL22 seated a little deeper than before and the accuracy was there, i'm not sure what did it but I guess it doesn't matter at this point.
 
Both my son and I found the TSX and TTSX to leave way to much copper fouling in our 2 Rem 700s in 257 Bee......destroyed accuracy after less than 30 rounds....moved to 110 ABs and RL 25 for some unrealistic velocities and 1/2 moa groups. I highly recommend this combo.
 
Barnes bullets need Barnes data. Making up your own is exceedingly unsafe. There is 115 grain data on Barnes' site though.
Changing the scope will do nothing for the accuracy if the load isn't accurate out of your rifle in the first place.
 
I'm using a Max load from the Barnes manual, the scope wasn't faulty but the reticle wasn't working for me and changing the scope allowed me to check all the ring/base screws, also seating them deeper may have helped as well.

I disagree completely... the FIRST thing you do is ensure that you have a solidly mounted, tested optic... there is no point in testing loads until you have that straight. Once the gun is checked and double checked to be solid, and after a few rounds to season the barrel, then load testing begins...

Where do you get your information from, I suppose you can only use Berger data for Berger bullets and Nosler data for Nosler bullets. WHAT BS !! You may interpolate and extrapolate all you want as long as the normal safe loading protocols are followed, there is nothing unsafe or dangerous about it. Learn to read your brass not BS.

I tried working up to the Barnes data when using the TTSX in my 7mmstws, but pressure signs prevented me from using the maximum published load in the Barnes manual. On the other hand, the data from one of my Hodgdons manuals which lists a maximum powder charge of two grains less, works very well in my rifles.
