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

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

26.3 gr H-335 & a 55 gr nosler BT, hornady Vmax or sierra blitzking | |||

I 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. Matt FISH!! Heed the words of Winston Smith in Orwell's 1984: "Every record has been destroyed or falsified, every book rewritten, every picture has been repainted, every statue and street building has been renamed, every date has been altered. And the process is continuing day by day and minute by minute. History has stopped. Nothing exists except an endless present in which the Party is always right." | |||

The twist rate is 1:9. Thanks for the reply

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. | |||

Thanks 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.
