Way over max load, no pressure signs...WTF?

Here is the thread I'm watching there now it is on 200gr & 230gr Beartooth WFNGC's and IMR 800X powder.

I have about 250 of the 200gr Beartooth bullets still I didn't know Marshall made 230gr ones though, I'm thinking that I am going to have to try and get some of them. :cool:

Just called Beartooth the lady there stated that they aren't making the 230gr bullets I'll have to call back and talk to Marshall when he is in.

I do not share that opinion at all.
I have found primer pocket tension to be a very valuable tool in estimating pressure.If the primer pockets are loose after two or three firings,I reduce the load even if the load is not listed as a maximum load in a manual.If there is resistance upon lifting the bolt,or if there are extrusion marks on the case head,I reduce the powder charge.
As well the maximum powder charge listed in manuals can vary by up to five grains from manual to manual in the larger capacity rifle cartridges,and two or three grains in the small rifle cartridges,even with identical components,so which manual is correct for your rifle?
Blindly trusting that all loads listed in all loading manuals will be safe in your gun,is a good way to get yourself into trouble.Even the loading manuals themselves post a disclaimer and suggest that you work loads up from a starting load WHILE WATCHING FOR PRESSURE SIGNS.

someone may have already said this but the signs of over pressure might be noticeable in a 300 win mag but in a 38 sp for incests would take crazy high pressures to crate any signs. That being said i have accidentally raised the pressure in my .303 br so much that it flattened the head stamp beyond recognition without damage to my rifle.

The .38 reacts quickly to high pressure. If ejection becomes sticky in a good quality sixgun, you have exceeded safe pressure with your.38 Special. Unless by accident, why would anyone fire such a high pressure load in a .303, or any other cartridge for that matter? Accidents happen, but chances are you could read the headstamp in reverse on the bolt face, and you probably had to pound the bolt open.

Why would anybody fire a 303 with such a load? Because he didn't know that kind of a charge was in it.
A load that makes that kind of pressure didn't come about by using a bit too much of the slow burning powder, normally used in bottle neck case rifles. I think the writer was pointing out how strong the rifle actually is, to take such a load and stay in one piece.
Almost for sure, the 303 accidently had been loaded with a faster powder, not the powder he thought was in it.
 
I agree that not all cartridges lend themselves to reading the primers as a reliable indicator of overpressure. I have to wonder if this might be related to the interior case volume of older cartridges close to the era of transition from black powder to smokeless.
