It eliminates vertical stringing at ranges over 600 yards. I use a regular RCBS electronic scale that measures only .1 grain. It does work pretty good, but I want low ES for a few of my custom rifles. As for hunting my regular scale suffices good enough, but when you like to take it to the bench, I like better stuff.
Stan,
the issue with the RCBS scale is that the weight shown is not necessarily the true weight. The scale tends to "drift" over a loading session. As an example, pick a bullet to use as a check weight. After callibrating the scale, weigh the bullet. Check the bullet weight periodically and you may see a different weight displayed after 30 minutes or an hour. The bullet obviously does not change weight, but the scale is no longer showing the true weight. I've had a few of the RCBS scales and they all start off ok, but with time tend to drift, up to 0.3 gr over one loading session. Depending on what is being loaded, 0.3 gr difference makes a noticeable difference even at 200 yards, which is well within expected hunting distance.
That's pretty neat to be that exact, but why/what real need is it for? Bench rest or other type of precision shooting? For your average, above average hunter is this necessary? Not saying it's a waste of time but this level of precision weighting is geared for what type of rifleman?
Bass,
To my mind, shot placement is the single most important factor for making a clean, humane kill of an animal, and we as hunters owe that to them. I really do not want an animal to suffer.
I do not own a benchrest rifle, but strive for the best possible performance I can out of the rifles I do use.
I want the bullet to go where I aim, not kind of in the neighborhood of where I aim.
There are four critical components to making an accurate shot - the rifle, the scope, the ammo, and the shooter. All have a role in accuracy.
Ammo is an easy place to increase accuracy, and an easy place to lose accuracy.
Here is a typical practice target at 100 yards using my main hunting rifle, a 308 with a bipod and rear bean bag. It definitely not a benchrest setup. It is a long way from perfect, but striving for consistency and proficiency, which increases the odds of making a clean, humane kill on the animal. The practice is to shoot with a quick followup, stand up and move back from the rifle, then get back on it shoot two, stand up, repeat. This forces practice of getting on the rifle in a consistent manner. The difference in position can be seen, especially on the third line, second group on the right. The quality and consistency of ammo can show up even on this 100 yard target.
Better precision yields better field results. My wife is doing the shooting on the deer, I was running the video, but this is what we strive for with every shot.
