a friend has asked me to try reload for his .243 it has 18in barrel and 1/10 twist . he wanting to use 90grn sierra gamekings i think they will be to heavy for twist rate
i have Ar2208 has anyone had much luck using ar2208 . i also have Win 748 but dont think that will work ,
any advise will be appreciated
90gr should be fine in the 1-10.
If you are referring to the 90 grain Gamechanger (aka the confusingly named Tipped Gameking) it seems unlikely that it will stabilise in a 1/10 twist. Some quick searching reveals a whole host of people unable to get it to group in 10" twist barrels despite Sierra initially claiming it was intended to do so on introduction. Funnily enough the abbreviated Google search has 10" mentioned, but the official product page for the bullet now says 9" twist or faster:

What is your friend wanting to hunt with this 243? It seems like there may well be much better alternatives to choose from depending on their needs.
Ooops - the question was actually primarily about using AR2208 with a 90 grain bullet in a 243. Yes you can use it and ADI and Hodgdon have data for it. The ADI website seems broken (for me), but use Hodgdon to look it up as it's the same data (ADI AR2208 is Hodgdon Varget in a more expensive package):

You can create a functional load with AR2208, however the data suggests that AR2209 (H4350), Win Staball 6.5 or Win 760 (H414) might be better alternatives for better case fill and better velocity within published maximums.
2208 will work mate. I used to run 87s over 2208 with no issues. Send it
Yep loading 87 gr Hornadys with 2208
Nothing fancy, it just works.
I load 2208 and 90 gn speer hotcore in a howa 1500. Don't know the twist or velocity or ES ...... but they kill deer good.

I use 2208 with 87 and 90gn pills in my lads .243win. 42 gns from memory but need to check. Might be a bit more.
Stay tuned..

A while ago I loaded some 87 gr SP Hornady for a friend using 35.5 grs of 2208 , out of his 20 inch barrel we got an average speed of 2756 fps. While it worked and it killed fallow deer ok the 243 is better suited to powders like 2209 , Staball 6.5 , 2213sc, it likes slower burning powders. In the Noslar guide No 9 there is a listing for the 80 gr Spitzer using a Max of 39 grs Varget (2208) for 3300 fps which suggests my load for the 87 gr is a lightish load. As always use caution when working up loads.
People dont understand how effective and clean a powder 2213sc is in the 243. Stunning in a Sako heavy barrel 75 using 75gr.Quote:

That load has worked in several .243's. ADI 2206h and IMR4895 also work really well for 90 and under pills (based on rifles I have loaded for and used.)
I do use ADI2209 for heavier pills: 95 Berger, 95 Targex, 95 SST, 105 Targex. 105 over a stout load of 2209 getting 2900fps and sub moa at 300. This in a 20" Rem 700 9.25 twist. Unlikely to work in a Winchester, Sako or Tikka as they are 10 twist.
No idea whats up with the 90gn "Game changer" suspect it might be length, but any of the usuall 95's should work in a 10 twist, have fed 2 different T3's with allsorts and never had problems.
Just feed the thing 90 Hotcors or 90 NBT and all will be fine. 2208 is good as gold.
2208 is the business in 243. I used it with 105 grain Targex pills to get 2950fps out of a 20 inch barrel. This was a Truflite barrel that was pretty fast.
Nice and accurate too, had it clover leafing at 100 yards and had it out to 680 yards shootings rocks in a clay pan.
Also had a really nice load with 95 grain ballistic tips and IMR 4064. Unexpectedly great combo.
That's over 200 fps faster that it should be with 2208!
I wouldnt use 2208 in a .243, too slow velocities for me for general purpose deer weight bullets and I dont shoot really light bullets. A .243 should be going as fast as you can get it, like the .270. I have used 2209 for years. But just reading Tahrs comment above, I have never tried 2213 and should look into that.
I know I was surprised as well. I did up a ladder and just kept going up until I got pressure then came back half a grain. Turns out it shot really well too, happy days.Quote:
