Hi, just recently brought a Cz 527 in .223, 1:9 twist & am looking at using the Sierra 65 gn gameking projectiles & ADI 2208 powder. Anyone out there doing loads using these? Any help would be appreciated.

You want someone to give you a load ?
That's kinda crazy - each rifle is different. Start at the min load, work your way up and see what works in your particular rifle, with your particular brass etc.
Rifle - ADI World Class Powders and Ammunition
I use BM2 for the 65 GameKings. Other option is 2206H, that is a bit faster burning than 2208 - more of a 308 type case power in my opinion.
I've used them with 2206h worked ok but too spendy for bulk shooting.
Ive just started using them in a 9 twist model 7. As above 2206H is more suitable than 2208.
I use them with 2206h.
Have shot them in 7, 8 and 9" twists.
Great .223 hunting projectiles.
Had good results with these with both 2206H and 2208, top end charges, COAL 2.26". Magic on goats.
With all due respect & no offence intended ebf I know how to work up loads & understand the issues involved so just to be clear I'm not looking for a load.
I'm really interested in hearing other peoples opinions based on there experiences with these components - drawing from the collective wisdom of those who have experimented with them before I do. I thought that's what forums like this were for.
What sort of groups are you getting with BM2 & 65 gamekings if you don't' mind me asking?
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.....
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.

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.

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.
Anyone tried the new 64g Sierra, Game Changers yet?
I use them with 2208 in my savage 1in7 223.
Taken fallow at 430meters as well.
Knocked alot of fallow and goats over with them.
Got 65 game kings on the way.
How much jump to the lands do they like?
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.
I couldn't watch it....he waffled too much without getting to the point.
I went with 10thou off the lands and they seem to like it.
Loaded up 3 rounds of each charge weight with 2208 and 2206h.
2208 loads 3/4-1 moa
2206h loads half moa for all charge weights I tried.
Got up to 3100fps with a good ES at the top so will load up some more at that and see if its repeatable but looks very good so far.:)Attachment 149690
64 Game changers loaded 20th off lands, GRT ballistic Program said 24g of Vitivory N130 so tried 23.9g ////// WOW way to much, one near punchered primer although cci 400s are soft. Couple of cases, old ones showed signs of case separation. Yet no opening bolt pressure. Shot 1/halfinch no idea of speed, no chrony. Beware of ballistic programs.
Looked up the Vitivory advise & they come back with 21g max. Today put a scope on I trust results 21g half inch, 22g good group, 23g chronyed this time 3115 accuracy gone. After the negative feedback about these projectiles, basically using to tune a load, will change to 65g Game Kings.
Super quick range trip after work to confirm and zero the 25.7gr load.
5 rapid fire shots at 100y.

One click right from that and called it job done.
