load suggestions for tikka t3 270 wsm

[johnnywadd]

just bought tikka t3 270wsm need some accurate load suggestions for 130 or 140 gr. bullets

[spoonover]

The 110 TTSX has been impressive for me, 270WSM with 71 gr 4831 SC, Fed mag 215, seat the Barnes recommended depth.

Barnes site ?tip section (Because TSX Bullets are all-copper, they have different pressure characteristics compared to conventional jacketed bullets. In our lab, we have experienced best pressures and accuracy when TSX Bullets are seated .030″ – .070″ off the lands (the grooves or rifling in a barrel.) The majority of the time, we’ve seen optimum accuracy when bullets are seated .050″ off the lands, so start there. Then move backward or forward in .005″ – .010″ increments to find the “sweet spot” for your particular rifle.)

Here is all I have in my notes, copied from forums. The X die I have not tried, but info might be handy?


For those of you starting on the .270 WSM, my loads follow after many hundreds of rounds fired. 130 grain bullets get 68 gr RL-22. North Fork most accurate and by far the fastest, followed by Nosler Solidbase, Partitions and Accubonds. Speeds from 3455 fps down to 3325 fps depending on bullet and rifle. ----- 140 grain bullets get 68 gr RL-25. Most accurate Nosler Ballistic Tip followed by Sierra Gameking, Barnes XLS, Uncoated Failsafe, Nosler Accubond. Speeds from 3329 down to 3100 depending on bullet and rifle. ------ 150 grain bullets get RL-19, RL-22, H-1000, Magpro. The bullets are North Fork (fastest) and Nosler Partitions. Speeds from 3225 fps down to 3102 fps. ----- Each of my rifles is equipped with a Ziess Conquest scope of 3.5 X 10, two with 4.5 X 14, and one with a 6.5 X 20 Mil-Dot. They will all shoot one hole groups when I do my part from the trigger end. It seems that the faster the load the more consistent it is with accuracy. Now you know all I know about the .270 WSM's that I shoot, hope it helps. Good shooting.

Gentlemen ----- A word of advice on resizing the .270 WSM cases. When I first started I was having some trouble with cases rechambering after resizing until I screwed the resizing die down as far as it would go, then give it a little more twist. I then read about the RCBS X die that supposedly does not streatch the brass. I got this die and last winter resized 500 pieces with no problems. The instructions says to shoot the brass until it needs trimming, then resize with the X die and then trim to the "trim too" length recomended by the manuals and you are good for many shootings. It worked for me like a charm. Good shooting.
