steyrl.223 Remington
Im just running the barrel in on a new Steyr Pro Hunter in .223R.
Any advice on loads using any projectiles?

J.W. BluteI shoot heavier bullets (69-80gr) in my 223's and have had the best luck with Varget.
What is your barrel twist rate?

ColoradoMattI agree with Butchloc, only I like Benchmark due to cleaner burning and temperature insensitive. H-335 is great though. 335 meters great. Butchloc's powder charge is about one grain over hodgdon's published max for 55 Speer Soft points. Plastic tip bullets usually raise pressure a little. I would work up to Butchloc's load in your rifle starting a couple of grains lower. No offense to Butchloc. I'm sure his load is fine in HIS rifle, and will probably work fine in 99.99% of all 223 rifles. I use hot loads in my 222, but I will not quote hot data on the net. All of that being said, their might be some published load data out there that mirrors Butchloc's load.

Do you mean just for running in your barrel.?
For shooting you will have to decide on a bullet weight to suit the target and range required. At 1 in 9 you can probably go from 45gr to about 70gr. A good local powder is 2206
about 26gr for a 55gr. projectile.

steyrlThanks for the reply. I started the run in process using factory loads and have fired 10 x 1 shot, cleaning in between each shots, 10 x 2 shots, cleaning in between and so far 3 x 3 shots, again cleaning in between. I have decided to finish with another 7 x 3 shots and then perhaps 5 x 5 shots using reloads. I have lapua cases to fireform and looking to start developing a load perhaps with 55grn or 60 grn projectiles.
My son is using a heavier grain match projectile with ADI Benchmark and Remington brass with really good results. However, I want to play a little during run in and fireforming.
