Test Range data- LR/PRS shooters especially what do you need?

[whiddengunworks]

We're about to open the can on some exciting improvements to our Rimfire Ammo Test Range. I'd like feedback on what new things the Test Range can provide that would be useful to you (besides of course plenty of cheap ammo of your favorite brand... that's out of our control).

When we test a rifle, we currently send a report that shows how each lot of ammo shot for accuracy at 50M and 100M. If the test is shot on the Megalink lane at our shop (tested with ammo other than Eley Tenex in other words) down range velocity data is also on that report, but you sort of have to look for it.

What if all of the data was presented in inches rather than millimeters? ...and measured center to center as we tend to do in America?

What if we could provide estimated wind drift data for each lot so you could compare?

What if we could provide estimated accuracy at long range? For example we can look at 100M accuracy and velocity spreads and can make a reasonably good estimate of 200 yard and 300 yard accuracy. Would this be valuable?

What if we provided velocity spreads in an easier to compare format?

What if we reformatted the entire results into a little cleaner summary? This might make it quicker to determine the best ammo, but we'd also include the current detailed report.

Your ideas will be welcomed!

That sounds like progress
Sounds like you are always thinking and working hard to make your service even more valuable.
We are all lucky to have you
Out here -shooters keep improving--matches get harder by the month to win--scores continue to get better so any improvements on your end are welcome
Thanks!

What if we could provide estimated wind drift data for each lot so you could compare?

This could result in slower lots outselling faster ones with little advantage to customers and it doesn't tell them how well the ammo will perform. Of course, when two lots of match ammo perform very similarly the slower one has the attraction of slightly less wind drift.

The question of wind drift due to velocity differences is far more important when comparing standard velocity with high velocity .22LR ammo.

On average wind drift will be directly related to MV. The slower the MV the less the drift. But there must be quite a big difference between lot speeds for it to matter significantly. Much more important for shooter success is ability to deal with wind.

To illustrate, consider two lots of .22LR match ammo, one at 1050 fps, the other at 1100 fps.

At 100 yards each 1 mph of crosswind results in about 0.03" more wind drift for the faster round.
At 200 yards each 1 mph of crosswind results in about 0.1" more wind drift for the faster round.
At 300 yards each 1 mph of crosswind gives about 0.17" more wind drift for the faster one.

With a 1 mph crosswind a high velocity .22LR round with an MV of 1234 fps will drift almost 0.2" more than the 1100 fps round at 100, about 0.5" more at 200 and about 1.0" more at 300 yards.

Would it be useful to identify lots with slower shots printing higher in the groups?
Just a thought.
