Consistency/ Repeatability

[One Shot One Thrill]

As a shooter I enjoy reading the diversified theories and practices to achieve ones own goal. In my findings there are many ways to achieve the end result but it must be repeatable. I'm always looking for a better way. I'm fortunate enough to spend more time on the range than most. Recently I have used the terminal velocity to aid with load development. I have found this information extremely surprising/valuable. With this info I can assess each bullets BC and determine when it effects the location impact on target. This has greatly reduced the number of shots required to determine a load. With the historical DOPE I have found I can produce a great load in less than 10 shots. This process has proven itself with 7 setups thus far from PRS to Benchrest Setups. It has been the most consistent and repeatable process for me to date. I am curious if anyone else is currently using terminal velocity in load development?

There is at least one of us that would like to hear more about the process. Do tell. Thanks

It is pretty simple as I have to practice the KISS method.
I generally start with the projectile at or near 0 in relation to the lands. I already have an idea on starting powder charge and I always start low. I do not concern myself with velocity as long as I'm within 200 fps of what the cartridge is capable of and I don't mean max. Depending on case size I adjust my charges accordingly example for 300 wsm I adjust in half gn increments. I only load 1 of each charge. I then fire them with lab radar at muzzle and electronic target captures speed at target. It is extremely easy to see/record what is happening. Usually I'll find 3 points with very little vertical that's all I'm looking for. At 1k it's .7 or less. I then load up 3 each of the different charges fire for group once again easy visual report. Note with the terminal velocity you can detect a bullet with a different BC. Every bullet has its own BC.
Then some final tweaking and I'm done.

Glad to read your post . Happy to hear DOPE used and understood .

Bob Collins used terminal velocity re: rimfire benchrest tuning years ago. Any overlap ?

I am not familiar with him but I'd like to talk with him.

Interesting as I need more than 10 rounds just to confirm seating depth, curious as to what kind of accuracy and consistency you are achieving with your minimal round testing?

The 10 rounds are to qualify a powder and charge window. Yes it can take a few to find the best seating depth. When finished load will shoot 3 shots a 1k in 3"range or less.

I qualify powder charge typically 10 rounds or less
