[QUOTE="Bigeclipse, post: 1034790, member: 52437"] compressed loads are not as bad as some may say. What I would do to check your compressed loads is to measure the bullet oal right after seating them and then let them sit over night and then measure the overall length again and see if it moved. If it didn't move, you are good to go as far as the compression is concerned. However, as far as using higher end loads from a book it is ALWAYS recommended to start lower from max (typically 10% is recommended) and then work your way up. before I do an OCW test I will always look for my max load. For example...lets say book values gave me a low of 50 grains and a high of 60. I will pick somewhere in the middle OR 10% lower than the highest charge and load it. I will then proceed to load bullets in .5 grain increments until I get to the max charge. Then go to the range and shoot these over a chrono graph if you have one. You can use these shots to check for brass pressure signs, but also to sight your scope in which you will need for your OCW test anyways. Make sure you shoot 2-3 fouling shots first...you can use over the counter ammo for these or load up an additional 3 rounds of the lowest charge weight. Now, once you reach book max, stop there and then run OCW test. The chronograph is useful in that it will give you velocities AND it will show you if anything funky is going on. P.S. you should run this pressure test on whatever seating depth you intend on using in your rifle. [/QUOTE]
