HM1000X initial chronograph measurements: A Google GLASS perspective

Check out the video of initial chronograph work on a Rapid Air Weapons HM1000X.

Air Gun Hold Over with a Weaver Kaspa Scope

So I have several different scopes that I have been using for air gun competitions. I have two Kaspa 3-12X scopes, 30mm bodies that reticles which help deal with hold over.  So lets compare what the difference between the velocity available to a TM1000 (about 800 fps) and and HM1000X (about 940 fps, so lets use 920 fps) for the kill zone as well as the point of impact for this scope.

Shooting a 40 yard zero with the 25 caliber TM1000 at 795 fps with the 25 grain JSB Diabolo Kings, the following ranges match up with the reticules.  The software, Hawke ChairGun Pro (v4.1.3) is really a nice tool for working out shooting angles, kill zones, etc.

Weaver Reticle View at 90 yards

The Weaver scope has (at 12X power) cross hatches at at 2, 4, 7, 12, and 15 MOA (15 MOA not shown).

First lets compare the kill zones (since the flatter shooting pellet can be zeroed out more).  The kill zone I established is +- 1/2 inch on the point of impact (POI).  So you can shoot at most targets dead on in the kill zone range.

800 fps  11.4 to 45.2 yards with a 40 yard zero
920 fps:  13.0 to 50.8 yards with a 45 yard zero

Now lets compare where those reticles cross using the above power levels
                          POI (yards at moa)
MOA            800 fps            920 fps
0                     40                    45
2                     55                    56
4                     64                    66
7                     74                    79
12                   84                    96


So obviously we get a bit flatter shooting, a better kill zone, and of course more kinetic energy.  About 48 fpe at 920 fps, and about 36 fpe at 795 fps.  In the coming weeks I will test the accuracy and find out if that extra power comes at a cost, or if we can shoot the HM1000X at full power.

Stainless Steel F-Class Rest (by Gary Hayes)

Check out my video regarding the assembly and basic operation of an F-Class front rest.  This all stainless steel rest is built by Gary Hayes in Canada.

Quality father daughter time at the range

Quality father daughter time at the MRPC bench rest range.  Weather was pretty nice, and it felt great to get my rifle zeroed in for the meet next week

Freedom Arms Pistols

I finally got out to do some shooting. I loaded up my 7mmBR Freedom Arms pistol with the following

1. I had some Lapua brass that I had neck turned for a 6BR project. 45 pieces to get started.
2. The decapper on the 7BR die is the wrong size for Lapua brass. So I had to steal it from my 30 BR die and decap the once fired cases
3. I lubed inside the neck and sized it up to 7mm using a Sinclair expander tool
4. I resized the cases with Redding 7 BR dies (minus the decap pin). I still used the expansion ring so that it expanded the case neck to have normal tension
5. I cut the cases down to 1.51 inches using a Wilson tool
6. I used a sinclair primer seating tool to seat Federal 205 (small rifle) primers into each case
7. I added 23.0 grains of H322 powder to each case using a
8. I seated 177 1/2 grain Bob Cauterucio bullets to an overall length of

I check the cases in the chamber and closing was a bit tight. I will need to set the shoulders back a bit more on the remaining cases.

Firing the gun was great. Recoil was very manageable.
