ksubuck - what a fine group! It appears that we both have had excellent experiences dealing with Mr. Elkman Mine was only a rangefinder - but excellent shape and excellent price, and what a gentleman to deal with Happy shooting!

Elkman did pass on a treat to me. I feel guilty with the success I have found with it. Time to find another way to pass something on to a young shooter this summer. There are plenty of candidates at the gun club, though with all of the noobs I sometimes feel like investing in some body armor. Had a lady put 30 some 9mm rounds into the baffle not long ago... maybe she could use an old pair of my glasses

I have also had dealings with Bill (Elkman) and mine were very satisfactory!

Verified the load today. Not a bughole... but 20mph headwinds with gusts may have played a role in that. 100 yard 3 shot group 0.572 inches, 200 yard 3 shot group 0.866 inches with some horizontal spread. Chronos at 3165fps which is right on target. SD 10 ES 24. That load is done!

168g LRABs are gonna be a little more slippery... ran some seating depth changes to see if I could back off the lands more so I could fit the magazine, and didn't find any benefit yet.

A fine load, even with strong winds. Good job!

Congrats on the STW! I know Bill had more than a few choice words about that rifle and said it caused a few headaches also.

 

[ksubuck]

Got the 168gn LRAB dialed in I think.

76.0gn IMR 7828 looked good previously, so I loaded 75.7, 76.0, and 76.3 to see if I could narrow the charge down.

The 76.0gn load did this. I only see two holes and there were no extra holes anywhere on the target.



And the 76.3 opened up a bit



I think the third round poked through between the first two and tore the paper but I can't tell.

 

[Oldtrader3]

Think you are correct?

 

[SJB358]

Wow! That looks pretty promising! Great shooting. Any idea on the speed of that load?

 

[DrMike]

Most gratifying groups for you. Looking good.

Verified the load and ran it over the Magnetospeed today. Fouling group 1.027, second group 0.780. Magneto said 3208fps SD 8 ES 27 over 10 rounds. I expected just shy of 3200.

 

[SJB358]

That would work for me!
