Thread: 308 Max loads

As stated by others, you can probably cram more powder in if you want to, but why would you want to? Loading to max pressure or possibly beyond is to take the track of diminishing returns. Your brass doesn't last long, any extra velocity gained is mostly gone in the first 100 to 200 yards, shock stress to your action is cumulative and you risk a premature action failure which could be to you or to the poor bastard that you on-sold it to. If you are looking for better long range performance, then seek a better bullet. The highest BC bullets in 30 calibre require a larger case than the 308W to give good performance at reasonable pressures

Valid point but often book data max is well below even factory ammo speeds which of course have to be loaded to be safe in the lowest common denominator.(old worn weak actions)

IMO and only my opinion (for a hunting rifle)if you are not achieving close to or above factory speeds with better accuracy then why bother reloading?

Not quite sure where you got the idea that factory ammo is faster then home loads. I'd suggest you go to the SAAMI website and see what the max pressure limits manufactures are allowed. They have to account for old actions, hand loaders don't. Try 47grn 2209 under a 208 match. Pressures are way over the spec of 50,000cup but the action is a barnard and cases binned after three reloads.

Factory ammo is often faster than book max data which is why one should work up a load to find max in your own rifle which may or may not be many grains above book max.
This is the point I was trying to make.

Ok sweet il try a nice day & a bit more powder , I was hoping to seat the bullet just behind the lands but the mag wont allow it ..thanks for the reply's team.

Everyone is entitled to be as innovative and adventurous as their intelligence allows. Why, I knew a chap up this way with only one arm as a result of fishing with gelly. Go for it I say, after all, what could possibly go wrong?
