Finished my other 7mag this one has an 8 twist and will be for McGuires and Hammers whichever performs best. I love the burnt bronze. 
Look Basil Twins!

They look great but they are both wrong handed.
The last one was a 1:8.7 and it works great with the 180 Bergers. Hoping to get some copper up to 3100ish
With this one.
Day one is in the books. I’m gonna try 72 grains and keep working up to pressure. I thought I would have hit it but not yet. Look at the notes this was also a shoot clean session. Fist shots were way faster then second two shots for each charge were very close. I think this is gonna be a good barrel. These are all 143 McGuires .020 off lands with Retumbo. I’m hoping to get a solid group with a 3100 avg. 
Ill post up some more pics tomorrow didn't have time yesterday but those were the 143 McGuires. Got up to 73 yesterday and produced another 1/2 inch group north of 3100 fps. I had loaded up the last of the McGuires I had at 70 and ran them out to 600 and the group wasn't that good. Ill try some more when I get them but if they arent grouping good at 600 I may try the 155 hammer.
