I had the same result with the 4831 right about at 52.5 grains I had a tight bolt and some marks on the brass. I was thinking this is max for my rifle with the 4831sc because I did not want to damage my rifle or me. My volicity was barely reaching 2800fps. I switched to the hybrid 100V and got to max book load at 49grains at about 45 to 50 degree temp outside. made a mistake the 100V is not temp stable. Vol was 2845. Went out and shot the loads at 80 degrees and had tight bolt lift with marking again. Vol was up to 2917. So now I am testing the retumbo out. So far it looks great. I'm going to do some more volicity testing to try and match my turret now since I originally bought one using the 100V at 2845. I'm also going to run the retumbo to max book load and see where the volicity ends up at but if my brass start getting marked and the bolt gets tight again I'll back off. But with all this being said I was seeing some similar results with the 4831sc like you are talking about but just not seeing the volicity out of it.
So I have a question about your load. What length is you COL and if possible the OAL as well if you care to share. Input would be greatly appreciated. Thanks. So for I know my COL is 3.11 on what I have been loading. My gun seem to like this length. I need to find my tool to measure the OAL.

Brent.
Not sure how good these pictures are. I took one of two 4831 brass and two retumbo. The shiny ones are the 4831 ( tumbled brass). The dull ones retumbo.

I'd don't have a device to measure to ogive. All I normally do is measure with one bullet and set the die with that bullet. Measuring several bullets to the tip with a set of calipers I come up with an average of 3.242". Because the tips vary some rounds measure as short as 3.238" and some as long as 3.246".

Thanks for the length measurement.

(Not sure how good these pictures are. I took one of two 4831 brass and two retumbo. The shiny ones are the 4831 ( tumbled brass). The dull ones retumbo.)

In the first picture the two on the left is from the Retumbo loads and the ones on the right are the 4831. So on the Retumbo loads there is scratching or marking between the 6.5 and the 284 that look like it is made from the bolt. I also had this same marks on my brass and then another little mark which I'm pretty sure is the little pin in the bolt face marking on the brass. This was all done at 52.5grn of 4831sc. Also the bolt was tight when lifting a fired round. So I figured at this point I was over pressure and did not want to go any higher. I backed off a grain and made some loads. They seem to be ok with bolt lift and only a very faint mark on the brass without the round pin mark. But the volicity was under 2800fps on the chrono I have. I just thought of something...I was also using another chrono graph at the time that gave me lots of trouble so my volicity may have been higher than I thought. With the old it always would the 51.5grns I was about 2770fps at muzzle. I now have a different one. But as anyone know the loads need to be shot at some distances to be valid. Good thing is the chrono I use now actually seem to measure the volicity pretty good. So I will be interested to see what Brents input is on your cases.

I am not sure if I can see well enough to tell. I will say this, I can take a brand new piece of brass and get scuffing on the face. What I look for is cratering, flattening, and the pin hole mark. In fact I am on the very edge with my rifle and occasionally will see a extractor mark. I think you have it figured out.


I shot my rifle again this weekend and I am pushing pressure I think, 3000 fps is what the program likes and the bullets are following that solutions path, but I am on the edge. Bolt life is fine but the signs are there. I am unsure of what to think about performance at 1530/1540 yards. Most of the strikes were hard to see so my groups were not easy to verify. At 1300 the groups look solid and under 1 moa. So far everything under 1300 has been great. Beginning to wonder if a 160 matrix would be better for the longer range. Not sure the 140 pill is heavy enough to buck the elements at those ranges.
