Chris I am definitely seeing progressive improvement in your groups. Sub o.4 MOA at 300 yds is nothing to sneeze at.👍
I'm willing to bet that at least part of that is better brass prep.

I have a mea culpa to come clean on: The printer I use for my targets is a new Brother laser, it replaced a Samsung laser that passed away after many years of service. Unbeknownst to me, the new printer does not allow for tight border margins, it just changes the scale of what actually prints on the page, in other words, an inch is not an inch  . When I posted my last target I assumed each grid on the page was in fact 1"x1", nope, more like 0.95866"x0.95866". Because of the way MOA calculations are made, some targets had higher MOAs, some lower, not by much but enough to p*ss me off  .

Anyway, mistakes happen, lesson learned, "trust but verify", "measure twice, cut once" and so on, lol.

Grant, very nice build...I hope mine turns out to be a shooter

Steve, I have a couple pounds of H4350 and an eight pound jug of Reloder 16 and Reloder 26

Thanks everybody, parts are starting to show up.

Quote from: Denver Steve on Yesterday at 12:19:58 AMDid you ever test out the retumbo in it like you said you where going to try?

I have heard reloder 23 is a great powder for the 7prc as well. Less throat wear than reloder 26 and temp stable.

Denver I did shoot just a handfull of rounds with retumbo.. the speed was a little low with it with pretty much a case full of powder.. I could have got a little more powder in it but the 1000 was giving me good speed and I didn't pursue the retumbo any farther

Worked on a load for this thing quiet a bit today with h1000.. had good speed with it but the precision just wasn't there for me.. the gun didn't react to changes with it like it should and I finally abandoned ship.. switched to rl26 and the gun immediately started acting like it should.. didn't take long and I had my groups down to a inch at 300 yards and I think I'm one more seating change to get it where I want it.. I'm a full grain below max charge in hornadys book and averaging 3015 fps.. that 4 groove 28 inch pipe is walking the dog boys!!

Every creedmoor I own, or have owned, absolutely loves the 140 grain hornady bthp and H4350 combination.

Tom here's a thread where I built the same gun a couple years ago. Not sure if it will help ya any or not but it might..

jvv2008, I have several boxes of Hornady 140 match that I was going to use in the beginning. Then start working up a load using either H4350 of Rolder 16, I have more 16 than 4350. Also I have Starline large and small primer brass.
