Thread: 223 Lapua brass

What is the 'context' you seek @ilikepie? Sanity check? Realistic velocity expectations? You don't mention if you are using a good chronograph to find out what speeds you are getting with your combination of components in your rifle.

If you give GRT good quality inputs then it will give you good guidance. I'm not sure if you're aware of it, but you can tune the powder profile to reflect what you have available more closely.
@grandpamac - in 223 the Lapua brass is similar in capacity to most other brands (in my experience). The one that might catch people out is the Starline brass as it is one of the lowest capacity brands on the market. It is great stuff particularly given the price, but caution is required (as always) when working up loads for it with data based on higher capacity.
