I currently load .243 Win for myself using Varget powder 35.5 grains/ 87g Hornady vMax and Fed large rifle match primers.
I am fairly new to re-loading.
I recently had a problem with cartridges fitting the rifle, with some tight and some would not allow the bolt to close. I put it down to the die not being in the press correctly (followed instructions to letter, but no resistance in final travel of press)
I therefore screwed die in (Redding Comp full size die, with bush/Redding comp seating die) and this cured problem felt a wee bit of resistance, almost a click in final few mm of press travel.
My questions, I have ogive gauge and headspace gauge.
Ogive on above bullets was fine so I believe it was the sizing of cases that were a problem (not fire formed in my breach/rifle). Can I measure the cases to ensure the sizing die is set up correctly?
Also, can I remove the de-capping pin and bush etc from the sizing die and "bump back" the shoulders on the loaded cartridges that do not fit the breach of my rifle without "pulling" the rounds? If so, will thos affect accuracy?
I understand I remove the 6mm ogive gauge and replace with the cartridge head space gauge, what measurement (in inches or mm) should I have and does it check for correct re-sizing?
Sorry for the convoluted post but I am keen to learn more and ensure I am safe at the same time.
