303B 174gr Sierra Load
Posted: Wed Feb 08, 2012 8:50 pm
Hi guys,
I have purchased a Mk4 303 to use in my clubs annual Commando 300y shoot in march. I was given a 2208 load on the range one day but forgot what it was so i was wondering if anyone can give me load data to make the 174gr SMK have the same velocity/trajectory as the military ammo?
I set up a dummy round to the length of the magazine as i was told this was the best way to do it. I have 2206H, 2208, 2209 on hand as i was planning to load a few round to shoot on the weekend. If no one had any ideas i will just work up top a max load of 2208 as it give me the 2500fps i am aiming for.
This will also be my first attempt at using peep sights so it will be interesting to say the least.
