.308 too much powder?

[victor1echo]

I do not recall what powder (4350) I was loading for my sps tactical, but the amount of powder came nearly to the top of the case. I felt like the bullet would be seated right on top of the powder. Is that okay?
Thanks

There are legitimate powder/weight combinations that will nearly overflow the case (i.e., compressed loads) BUT without knowing what powder/weight, bullet design/weight, OAL, your question cannot be answered with confidence.

There are so many variables: depends on the bullet length, case internal capacity (I have lots of LC with very thick walls), powder type and weight, maybe others I don't remember off-hand. If the max load indicates it would be compressed there's your answer right there.

I do not like compressed load. I use about 42 grains of IMR 4064 and it is fine for me. About 42 grains of IMR 4064, 4895 or Varget is a good load.

I concur. I have pulled the bullets from rounds that had compressed powder
charges after they were stored properly for over 5yrs and had caked powder at
the top of the cases. The powder probably found some leftover case lube
residue on the case neck and became one big clump of powder.

Would most likely would only affect accuracy, however one's biggest reason to
load one's own ammo is for creating accurate ammo.

Limits

I think military brass holds 56 grains maximum.

Winchester commerical holds 58 grains.

because generally, military brass often has thicker webs or casewalls.

Most load charts I've seen have powder numbers in the mid 40s and one on this chart is 47 grains..that's almost topped off...

me thinks you are mixing up info for 30-06 and 308.. I don't know of ANY 308 case that will hold 56-58grs

[Shoot-it]

I have that problem with H4895 with the 223 case. max load is 27.5 but it's hard to get it all in I have to tap the case.I now just load 26.8 it is more accurate anyway.

What bullet gr were you using in the 308 ?
I like H 4350 in big case's 270 7mm mag I never had any problem with them over flowing.
Be care full you don't want that rifle blowing up on you.

I was using IMR 4350 (BECAUSE i HAVE IT) with speer 168 BTHP, and Nosler's reloading guide #6 suggests 46 -50 grains. 47 was nearly to the top. Also there is nothing about being acompressed load.

Actually they are all Compressed loads. When you look at the table, look all the way to the left, where is states "Load Density Volume". A volume over 100 is compressed, and is also denoted with asterisks.

46gr-101%,
48gr-105%,
50gr-110%.

If you tricle it in slowly though a long drop tube, the powder will settle better and you might not have to compress it.

[G-forceJunkie]

How your funnel it in can sometimes matter as well. Try a funnel with a long neck and fill it from the bottom up and give it a few taps to settle it in.

Nothing wrong with that. I use 4895 because I found a good deal on 8 pounds of it.
Just go with a load that does not over flow this way you can pour fast and keep going.

Are you SURE you're looking at 308 loads and not 30-06 springfield loads??

No, that is correct. I checked my copy of the Nosler manual, and they are all compressed loads. IMR 4350 is not the optimal powder for that load, hence the compressed volumes to make it work.
