OK so I had some trouble with high pressure with some of my hand loads. I was 1.5 grains under max load at 69 gr IMR 4350 with a barnes tsx triple shock HPBT 168gr. When I seated the bullet I went with the COAL in the barnes book of 3.340". I was told after that if I seat the bullet to close to the rifling that there will be excessive pressure build up. When I got home I took an empty case and just barely neck sized it so I coould take a bullet and just barely push it in with my fingers, then leaving it really long I slowly chambered the round pushing the bullet in until the bolt would close. Then I opened the bolt and I am getting a measurement of 3.505". I have double and triple checked using this procedure and am coming out with the same measurement every time. So my questions are:
1. do I have a problem with my heaspace on my rifle if the recomended max cartridge length is .165" shorter than my "chamber length" ?
2. would this .165" bullet jump cause excessive pressure?
3. would it be dangerouse to load with a .010-.020" jump, and exceed the maximum recomended cartridge length as set out in the manuals?
Thanks, Mark.
