243AI powder recommendation

[Bominiscious]

I am brand new to the reloading game and have a Model 7 being rebarrelled to 243ai. I need a recommendation for a powder to reload for this.

Thanks!

What twist barrel?

What bullet?

 

[Bominiscious]

I am going to start with 90 & 95 grain Nosler BT's and 90 grain Accubonds.

Barrel is a Lilja with 8 twist (I am checking on that twist rate to make sure).

My 243ai shoots 85 gr Sierra BTHP for groundhogs and likes several powders including Reloder 16, 26, VV 160,560, 150, 555

H4350.

I use this powder in both my .260AIs, my 24" with 130 OTMs @ 3068fps and the 20" w. 140s @ 2914fps. It is not the powder to give the fastest speeds, but it is clean, stable, and accurate.

I also use it in my 22GT, 6CM, two 25CMs, and 6.5SLR.

VV 160 is clean burning and the right burn rate, I used it my 6mmai.

H4831 is the best I have tried in 2 different 243ai's wit 100-105 grain bullets.

RL15 pushing 88gr Hammers. Very accurate. Will get you my load data once I get back home.

For those bullet weights, I'd lean toward H4350 or possibly Stabal 6.5, for 100+ grain projectiles, H4831 or H1000 (if your throat is long enough to allow for enough powder).

I do have some H1000 I'll give that a try before I order some of the other suggested powders. Was hoping something that I already have might be an option.

I've had very good results with 6.5 staball. Needs To be near max for best burn and SD's.

My 243AI Load 2.223 BTO, 38.6 RL15, 88GR Hammer Hunter. As always work up to that load because this is a load according to Hornady.
