In the Encore, sticky extraction is one of the better pressure signs to watch for. The extractor system on these rifles is pretty week and you will feel sticky extraction long before you would on a bolt rifle.
That said, always watch for flattened primers, primer cratering and such.
With the Encore, they will generally shoot the best if the rounds chamber easily. A snug fitting case will often cause fliers with these rifles. As such you need to size the cases more then would be common for a bolt rifle and as such you may see more case stretching as a result.
Simply put, a chronograph is the single best way to get an accurate idea what your pressures are doing. Velocity is a direct result of chamber pressure and time.
When loading for others or customers I always load to what the recognized loading manuals tell you to, to the letter. These are proven loads and while they may not be the very top potential a certain rifle or round can produce, they will certainly get the job done and will keep you from paying some lawyors kids way through school.
Best thing to do is include your boss in the process. Have him come over and be involved in the process.
Again, do not look to hotrod loads for someone else, will just get you in trouble. You are looking to load for total reliability in all conditions because you do not know where they may be used.
For pronghorns, temps can range from below freezing to near 100 degrees so you need to load your ammo accordingly.
Remember there is some degree of liability issues you are taking on here. Some I know make guys sign waivers to use their ammo. That is up to you. Legally I am not sure how much water that holds but I know several guys that do it.
Good Shooting!!
