Powder for 223 Rem with 55gr sierra FB spitzers

[Bcnr33v]

I am about to reload some 223Rem with 55gr sierra spitzers (#1360). I am running a 20" 1 in 12 twist barrel.

I am tossing up between ADI BM2 or BM8208. Anyone have an experience?

My Tikka 223 goes good with 24.5 of 8208 and 55 gr pills.

Thanks. I spoke to Hogdon and Sierra tech overnight and both recommended to start with the BM8208

Have not tried the Sierra flat base spitzer 55 grain for more than 30 years as back then I found them too hard out of a 223 no problem out of a 22 250 though I use the 55 grain speer 25.5 grains of 2206 h and I get 3260 feet per second I use CCIBR4 or CCI 450 Magnum primers because of the fault with howa firing pin radius and diameter and firing pin hole size they have a thicker Cup use this load with a cci 400 primer and they will cookie cut as the 400 primer is designed for the very old low pressure cartridges like the 22 Hornet and such

it's hard to find a 55gn bullet that won't shoot accurately out of a 12 twist 223 with any of the powder suggested . bullet performance for the job at hand is the variable . personally i've used the 55 vmax for target work with BM2 at about 3000fps , but found better on game performance with the 55vmax loaded up near max with 2206h . your 20" barrel is probably handy , especially out of a vehicle , but may loose some velocity . probably not enough to matter if you put the bullet in the right spot . but i found in my use a little more velocity made a difference in terminal performance . don't use the 55vmax with a cannelure , as these don't perform as well from my observation . others will have their own opinions and observations , these are mine . i've also found ADI brass to be excellent , consistent brass , good value for money . let us know how you get on . cheers
