Thread: .270 and .223

Hi anderset20

I have been reloading the .223 Remington for a while now, at first it was for a bolt action Howa, and now for the AR-15, when I loaded the ammo for the Howa, it used to like the Nosler 55 grain Ballistic Tip Boat Tail, because that was what I found the barrel like, however since buying the AR-15 I have started to use the Hornady 55 grain Soft Point just because that was the cheapest projectile that I could get for the amount of ammo I am burning thru.

Each barrel will like different loads, it will take time to get loads down to 1/4 MOA or less (a friend of mine can do 8mm group over 3-5 shots at 100m using a 7mm Remington Mag yup that whole group was 1mm bigger that the projectiles!!)

My first question is what factory ammo do your like? then what is your barrel twist rate?

In my limited experience I think that it would be wise to get some sample packs and do some testing with the same batches of cases, powder, and primers. Write everything down from what your load data was thru to what your groups were, include anything you can think of even the range conditions as cold air is more dense to warm air.

Some data sheets you can use
