With some great help from Greyfox I worked up a load using the Sierra 130 gr 6.5mm Gamechanger for my Schultz and Larsen 6.5-284 Norma using Lapua brass, Fed 210M primers and Rel 26. I have only shot one Red stag with them so far which is the one in my Avatar. He was shot at 300m in the neck and the bullet left a 7/8" exit after hitting the center of the spine. This load will group at less than .25 MOA at 100m and will hold .45 MOA at 400m. Also I have been working up a load for a Carl Gustaf 3000 6.5x55 Swede with this bullet and Rel 23 in RWS brass. It also is shooting well with the 130gr with the best group so far at .433 MOA at 100m. I'm a fan of Sierra bullets and the Gamechanger has just added to the attraction.

Load them with a stiff load of Retumbo in my 7mm Practical, 165gr, extremly tight groups, long range target load, havent used them hunting.
What's your load and seating depth if you don't mind me asking? Twist rate? I've tried a handful of loads with my practical and h1000. Can't seen to get better than 1.25" group

I shoot the 130’s and 165’s at .020 off the lands. Both shoot great, no need to mess with seating depth.

I shoot the new 140 grain Sierra TGK in 6.5 Creedmoor. I get 2900 FPS with 46.9 grains of Superformance out of a 24" barrel Tikka. Sub .5 MOA accuracy, waiting to kill a deer or 2 with them soon.

I am shooting the 130 grain TGC in a 6.5 CM at 2850 FPS. So far I have killed a 200 pound whitetail at 225 yards. he went about 10 staggering steps and dropped. Around a 2 inch exit from the double lung shot and chest cavity was basically jelly. Didn't really push the velocity to max as I got this kind of accuracy at 2850.

I’ve heard some folks say the GameChanger is not a good expander at long range. I emailed Sierra and they said 1800 FPS is the absolute minimum for reliable expansion for the 140 grain 6.5 GameChanger.
