well obviously at least 600 of them were "minute of deer's vitals"....so they cant be too shabby.

I use 26.5 of 2208 behind a 69 Sierra hp by in LC brass in a t3 loaded to mag length. Use normal precautions. Start at 25 and work up in half grains.

Use them behind BM2 in a 1:8 17" tikka
Got around 2750 fps groups 1" or less
Has a few red stags now but bullet placement is key for big animals, do prefer 55 vmax for rabbits etc.....

Interested in hunting results of game changers as they are advertised as a hunting projectile. I'm setting up a lightweight 223 rig. Savage storm lightweight, 20 inch 1/10 twist, Dpt suppressor, vx2 leupy, comes in at ~ 6.5 lbs all up. Hoping to get 3000fps, capable of deer to 250 yards, so projectile performance is important. Bought a box of GCs but won't be able test and use for some months, so your feedback is much appreciated. PS - Game Kings getting a good wrap, are about the same price.

Your twist is 1:9
My older model of the same rifle stabilises 69 grn Sierra Tipped Match Kings and they are very good on deer.

I get 3048fps with 2206. 20" barrel.

Been a very easy projectile to get a good load with. Got a load with 2206h doing 3k and .5” or less groups at 100 and shot a .5” at 381y the other day from a 20” barrel

Is reloading as you suggest worth it? I use Aussie Outback 55 grain with Gameking pills and they are excellent. That said, the Belmont 55 grain s.p. Bulk ammo cuts the centre from the bullseye at 100m. Rifle is suppressed Howa mini with Nikon glass.

I load
Tikka t3x
65Gr SBT
ADI brass
26.4Gr 2208
1.90 " comparator [Waterman mag]
2970FPS


And yes, 3 shot groups but two of them one after another.

Thanks for the info guys, I'm hoping to squeeze out 1/2 moa & not so worried about max velocity but if the load does both it'd be nice, I think I'll try both 2208 & 2206h n see how I go. Groups like Jakewire posted would be perfect.

I reload for a mates T3 1:8 using them he get 1/4 moa and 2950fps with BM2.

Rifle Savage
Caliber 223
Projectile Sierra 65 gn gameking
Case ADI
Primer Winchester SR
Powder ADI 2208 26.4 Gn
To Ojive 1.996
Velocity 3120.000

Shoots .5 to .75 @ 100 meters

I'm literally about shoot/chronograph some 223 Sierra Gameking (RooMax 1365K) in 55gr that I loaded with ADI 2208 - if that's of any interest to you I'm more than happy to share my data.
