Drinking and loading do not mix. If you drink and load, please inform the shooters around you so they can find a safe place to hide until you leave. No two loading manuals will agree on a particular load, it's confusing to say the least. Don't replace one bullet weght with a heavier one and use the same powder charge. 30.06 with 180 gr bullet, or heavier with lighter.
Pressure is calculated in the manuals changing anything changes everything.
Here is a tip for you. OK no big deal you say. The bolt latch bent but held and the casing was in about 15 pieces. This is a true story, I swear on my cowboy boots.
