Yes and no. This is from a guy with 59 yrs. experience as a handloader.... Yes, I've blown a few primers..... Look up the data for the bullet you are using. Use that COL. particularly if using Barnes all copper bullets. Look at what case they used to develop the loads. Some cases vary a lot in capacity/weight. .308 Winchester brass, for instance varies a lot.
Or, what I do is read the data several bullet makers and strike an average mid range charge. Load up 3-4 rounds and head for the range. On '06'/.308 size brass, I usually increase powder charges by a full grain. as I increase the load.
Pay attention the air temperature. Loads developed on cold days sometimes are too hot on hot days.
Last of all, don't bother chasing the last 50-100 fps. It's pointless and hard on the brass. E
