Maybe, but perhaps not. Loads that are shown to be below “maximum” in our test rifles may prove to be too hot in your particular firearm. It is important to understand that maximums vary with several factors, such as temperature, even within the same gun. That load you worked up last fall may be more than a bit rough on your primer pockets when summer rolls around. Ask any prairie dog hunter who has had to shade his gun, put his cartridges on ice and avoid leaving a loaded round in a hot chamber too long. Now, take into consideration variations in components. This powder may be the same brand and type, but is slightly different in burning rate than the last lot you used. Your cases may vary within the same brand as to both volume and strength. Guns can vary dramatically from one another in internal dimensions. A short throat, a tight bore and a host of other internal variables may combine to create substantial differences even between two guns of the same make, model and chambering. HEED OUR ADVICE: START LOW AND WORK UP YOUR LOAD CAREFULLY!
