when i get a new rifle i like to find its pressure limits (when i start seeing pressure signs before doing load development this allows me to concentrate on shooting during load development rather than checking brass etc even more so when the powder im using has no real data only what i can find on the web and ask questions about
now my components are as follows
bullet:100gn serria hollow point
powder:hogdon cfe223
primer:cci br4
brass:hornady once fired from factory ammo full length sized
most data i have found by asking questions and trolling internet forums such as this one
seem to be anywhere from 31-34gn of cfe223
and asking a few pepole in the know determined 31gn to be a good starting point
so ive loaded 2 rounds of each number starting at 31gn-33.6gn working in 0.3gn steps
have OAL set to 2.200" for these tests will play around with that later
loads were done with the rcbs charge master auto powder measure and double checked with beam scales for extra consistency
now to go shoot some dirt i probably wont bother shooting these at paper as its just simply to look at fired brass might put steel out to shoot at
when i load for real i will be using lapua brass but didn’t want to risk the flash stuff for this testing
this means i will need to keep half an eye in brass during load development as all brass is different but at least i wont be 100% focusing on it
