Which cases, what powder, Primers? A couple of pictures would help too. When doing a run up on powder, you should be increasing by about 0.25 increase per load with that size of case. Single round increase for each powder loads. That's only to see what it will handle in powder charge . Generally I don't do a velocity check at that time. Barrel is new, and needs to be broke in. Velocity after brake in increases. Now you need to watch for pressure signs as you are shooting each load. The reloading manual is only a guide line. I only found one time that the loading data was away off in 60 yrs. I started off on there max load. Out came the primer and very hard bolt opening. I got to looking at what their power loads is, and other powder loads for other bullets. The were 5 to 7 grains more powder, and about 8 grs more in bullet weight in about 40gr case. Never repeated that again (I did find my sign "STUPID").I did the break-in on my new bergara B 14 wilderness Ridge today. I was shooting 130 grain burger 6.5 mm, and a nosler factory seconds for us. I did powder amounts between 49 to 55. I noticed that some of the braas was showing signs of pressure. I'm not even close to what the max was recommended by Berger. Let anyone run into this in the past and have any recommendations I am still new to reloading.
