Sierra 223 bolt gun data

Like rumbler said, diffrent weights match up better with diffrent powders.
For the 77 gr I am using varget because I have it..and I can use it in diffrent calibers..


For 55 gr I would use something else that is more suited to lighter bullets

I am planning on using h335 as there is data down to 40 gr with that, and the most important thing..I have it

Look at the load data and you'll see what we mean.
If you are planning on looking at loading other calibers, look at load data for them
You may find the same powder works for it or not..

For heavy 223's I can use the same powder as a 308 load..(varget)
Like always, check more than one source of load data to see if it seems in line with the other.
