Any issues with these cases - Pressure Signs

So what would you guys recommend as next step.

I’ll redo the ladder at 300 as I made 3 of each charge so have some.

The range is far so I want to maximize the visit.

Based on the data above. Should I explore the 41.5!/ 2700 range with 5 shot groups?

Should I load higher then 41.9 and see if better mode at higher charge.

I’m happy at 2700 so wouldnt go higher unless it would provide significant accuracy benefits.

Or should I just redo ladder and look at that before anything else.

Appreciate all the help.

As stated, if you don't have pressure testing equipment, a chronograph is the best indicator of pressure.

All other "signs" are mostly subjective and are all notoriously unreliable, but worth noting. In particular loose primer pockets suggest high pressure (at least for the strength of that particular brass) and I'm reluctant to lose brass before at least five firings and will lower the load even if it's "safe", so long as accuracy remains acceptable.
 
What is your goal with this rifle? If you find accuracy adequate at 41.2gn and the velocity good for you at +- 2700fps then stay around that and play with sitting depth. I would do a five shot group at 41.2 and record each shot where they land( my last 5 shot group I had 3 inside .75” and then a fourth that made it just under an inch and the fifth one screwed it up lol!
Anyway what ever you do keep the info coming here!
 
Ya I was thinking of a 5 shot group around that charge..

Im trying to get into the 1000 yard game so want to develop a good long range load. Obviously challenging round here as not many places to actually shoot that distance for practice.

You're title asked, "are there any issues with these cases?" Yes there is, my response is, "purchase quality brass." You have scraped the bottom of the barrel with Hornady brass. Lapua, Peterson and Alpha would be an excellent start.
