Hey guys

Just picked up some 178 gr Hornady A-MAX for my first reloading session. It was all that was in stock in 308.

I see some comments that are saying 178gr is too much for my M14

Does anyone have any experience with this weight thought their Norc??

Thanks

From the reading I have done the 180gr bullets is pretty much maxed out as far as the gas system, I have shot 180's through mine with no ill effects. I don't think I would feed it a constant diet of 178/180's.
I would look into a grooved piston, which is supposed to let you shoot heavier loads more safely.
This being said I am starting to gather parts for a build, that I have every intention of exclusively shooting the 178 amax out of, assuming it likes them that is.
 
Turn off the gas and you should be OK.
Ive sent plenty of 180's thru mine with no ill effects with the gas off.
 
Those comments are incorrect. Doesn't matter if it's an M305 or M1A either. SA Inc., does void their warrantee if you use reloads. Not that it applies to you. Personally, I've never seen any semi-auto rifle get damaged by the ammo.
When you get that far use 180 grain data. Two grains won't matter. Mind you, 175's and 178's are best for distances past 600. 168's for out to 600 and 150's to 300. 165 grains for hunting bullets. Use either IMR or H 4895, IMR4064 or Varget. With IMR4064 being preferred over either 4895. These are not the only powders though.
 
I was once told that 180gr was confirmed fine by SAI, as long as it's not used for sustained fire. Let your rifle cool down between shots and it will be fine. That or zero your rifle with 180gr, go hunting then get back to lighter ammo.
 
Appreciate the input guys. We used IMR 4064 and loaded half on the lighter end and half in the medium range per the Hornady reloading manual.

Cheers
