Hi,
Well I finally got out to the range with my "new" Ross MkIII...
And it shot well!
Granted this was my FIRST time reloading... so I was using the following:
Brass: 1F Winchester
Bullet: Hornady 174gr FMJBT
Primer: Winchester LR
Powder: IMR 4895
The groups were very good... using iron sites at 100 yds the groups were:
34.0gr=2.25"
34.5gr=3.0"
35.0gr=3.25"
35.5gr=5.25"
36.0gr=3.0"
Now each group was 8 or 9 rounds (I needed a few rounds to set the sights!)... and each group had 2 fliers high (which weren't counted)... I'm not sure if that's me reloading incorrectly or what... but the core groups were very good... I should add that each powder load was measured individually using my Lyman 1200 powder scale/dispenser...
Also... The brass was FL sized before... and 5 out of 50 cases split the neck...
Is that due to a reamed out chamber? Or do I need better brass??? Or is the pressure too high (the OAL was the minimum in the manual... and my powder loads were 34-36grains... where the max was 41)???
Here are some pics of the groups...
I'm excited to keep trying to find a load that it really likes!
