Got a few questions as a new reloader.. I've seen some videos on YouTube from some great competition shooters. As well as digging through all the forums regarding powder charge and SD and ES.
Does ES matter if im only shooting out to 500-600 yards or should I ignore it?
Few people have told me you don't need a chronograph to get your es just shoot paper? Elaborate if possible?
I doubt I'd shoot out past 600 yards ever. This would be for a hunting application.
Shooting a rem700 tactical 18" 1:10 Twist. the load I'm looking to work on is the eldx 178grain. Varget powder.
Any and all other information/advice welcome. Thanks.
Yes and no....
I would never tell you MV or ES/SD "don't matter". They certainly matter but the main point is the priority is on the target not the chrono stats.
If your recipe doesn't agree with your rifle or if you load sloppy then those stats are an indicator of a problem.
Poor ignition will also lead to sloppy ES/SD issues, so a chronograph can be used to monitor the health and cleaning needs of the rifle as well as help with external ballistics.
Now, within reason you can get away with a less than stellar ES/SD and still have a recipe perform well up to about 600 yards for a hunting application. Many folks learned to develop very good loads and shoot to very high performance levels before personal chronographs were proliferated.
As a rookie, you have to give yourself time to set your foundation and get some experience. As you build your skills and process, you will learn to smooth out your workflow. Your recipe may or may not be optimum, but basic skills can still get you to performance levels that are perfectly acceptable for hunting situations up to about 600 yards.
By definition, when you develop a load by letting the targets do the talking, the velocity stats will be "good enough". However the opposite is often not true in that really great velocity stats are not a guarantee the gun likes the recipe in terms of the target performance. There are no prizes given for chronograph stats, so keep the target prioritized.
When folks said you don't need a chronograph, they were not wrong because it is technically true, however....
Whenever you are still in the learning curve of internal and external ballistics, it is good to know the velocity as a proxy for the pressure and as an indicator of quality control, even if the ES/SD does/doesn't spoil the vertical performance at distance.
Just one more comment, Do not stare at the chronograph as the priority. Too many rookies fall into the trap of "The 10 Shot Satterlee Method" and think they can develop a load by looking at chrono stats or "flat spots". Those "flat spots" in velocity ladder tests do not exist.
Your priority as a rookie is the safety first, then performance on the target, then the chrono stats as time passes.
