Default 300 weatherby mag jamming

Was shooting tonight. No issues shooting weatherby loaded ballistic tips 180gr. No problem shooting hornady loaded eldx 200gr.. but nosler loaded 180 nosler accubonds.....they........ Shot the lights out, but jammed after every shot. I could stagger nosler for hornady for weatheby brass loads.. and the nosler brass jammed each time.

The bottom of the case was shaved slighty and almost scrape marks a the top of the empty , bolt handle was very hard to lift and had to give a bit of gas to pull it back.


Any thoughts?

Sounds like too much pressure for the Accubonds , maybe because the Accubond has a different profile , try backing off the powder charge a bit for them,or maybe a different seating depth.

Come on Alberta Bigbore ! You know the answer to that question.
You seen the flatten primer ! Every different shell brand or powder or amount or bullet brand or style or even primer can change the pressure ,even how deep you seat the bullet makes a difference .

I think you posted this because you just did not have 4 test loads you were testing , but maybe you loaded 100 rounds and then you said f.u. c. k. what did I do !

Too much pressure, I have seen it before with 300 Weatherby brand factory loads. And the brass will likely be scrap because of loose primer pockets. If you have one round that does this be careful, two rounds, stop shooting them.

Difference in brass volume and or softness and possible bullet profile and or hardness = pressure changes .

As they say “ keep brass separated “.

Are these factory loads or handloaded?

lol YEA ! That factory loaded Nosler 180 ABonds are too HOT loaded For YOUR rifle !
Simple FIX ! Just Don’t shoot them ! RJ

You could email Nosler with the LOT number from that ammo and ask them if there is a problem with lot being maybe overloaded ? See how they respond .RJ
