Rechamber from 7 RM to 7 STW?

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

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.
