This week I got to velocity and terminal check my last batch of Hornet loads: ADI AR2205 9.8grn. Sierra Varminter/Hornet #1200 40grn SP. I didn't shoot a cardboard target too assess grouping, just carried on from the previous load #1210 45grn SP with same powder charge. Surprisingly I hit more than I missed so POI must have been close to the same. That was just lazy prep and lack of time.
I ran a few through the rabbitonagraph velocity checker and was pretty happy with the results:
Then I ran one round through the possumonagraph:
The possum was 50 or 60 metres, standing up on the ground, looking the wrong way.
I'm pretty happy with these little 40grns and reckon they might become my go to.
Be interesting to see how they go on goats....
Velocity is hard to guess!? The various reloading manuals, (for similar or equivalent Brand powders) show:
- ADI AR2205 2421 - 2567ftps
- HORNADY 2400 - 2500 OR 2600 - 2700
- Sierra 2100 - 2300
- Speer 2639 - 2782
So it's really anybodies guess?
Is the NZHS Forum north island chronograph anywhere near Wellington/Kapiti? I wouldn't mind doing a more scientific velocity check? @SmokeyJason @Micky Duck
@Marty Henry how's your K mate getting on sorting out processes?
Also @blip how are you getting on with your K?
