I bought some federal gold medal match ammo to see how my rifle likes it, but realy for the brass. I shot it all up and it stood up to its name. I just got done cleaning and primming it and decided to weigh it,84.5 gr. does it build alot more pressure than winchester brass and if so how should I adjust my load? Thanks for your input
 
Re: fgmm brass question

84.5 grains? Did you mean 184.5 with primer? Winchester brass is thinner and you can get more powder in the case. You should reduce your load somewhat. Also the brass is softer.
 
If you mean Winchester commercial brass then yes you’ll need to reduce the powder charge.
