Cartridge pressure signs

The big downside i've experienced with suppressors is they seem to induce stiff bolt lift in more circumstances. Can cause condensation or fouling in a chamber from holding that gas in the barrel and can cause cases to not grip chamber walls as well so you get more bolt thrust and in turn stickier bolt lift. Seems to get bad primarily for me in MN winters shooting into the wind

I feel like this isn’t spoken enough about, good information

I’ve noticed the same. Do we think that is due to increased bolt thrust due to back pressure, more carbon fouling or both?

The most notable issue seems to be condensation for me. Cold with some humidity, wind blowing from target direction seems to be the combo. First few shots seem fine but 5 or so without a break for the bore/chamber to equalize more with ambient and sticky bolt lift comes on.

A gas block is the link between barrel and gas tube that gets gas from the ports in a barrel into a gas tube back to the bolt carrier group to cycle the action on an auto when fired.

Not applicable to bolt actions.

Got it. Thanks-

ADG is a brand that manufactures brass, like Lapua and Nosler and any other brass manufacturer. ADG brass typically has harder case heads than most. Because of that it takes more pressure/bolt thrust to show ejector marks on the case head than brass that typically has softer case heads like norma, federal, and hornady.

Ok, Im doing load development for a 17 Remington. 30 Gr bullet using staball 6.5.

Beginning load. I noticed cratering but no primer even beginning to chance shape like filling in.
