thank you for the reply. Since I am not a builder, what consists of a vapor barrier? plastic or some specific material, is there a name for it? Lined with a water resistant material was my thought also but I don't know what material to look for. I have seen them in videos but no one ever...
I want to build a walk-in cooler for hanging deer in my barn. I plan 8x8x9 ft with barn having a concrete floor. I will still insulate the floor. The barn was designed for a walk-in cooler (before I bought it), so it has a drain installed in the floor. For those of you with building...
With my 18" barrel, I feel like I am good to 500-600 yrds, @2800 fps+ 168gr LRX. The rifle is well balanced with the suppressor attached and very manageable.
FYI I have been getting Herters 22-250 ammo for $24/box at Cabelas to reload. Its Winchester brass. For the cost of brass alone, its a tough price to beat and I get to shoot the 20 rds of ammo first to fire form it to my gun....

Update on my load workup. I went down many rabbit holes and ended up back where I started with 168 grain LRx bullets in my 18 inch 7 PRC. I loaded 10 rounds with 72.3 g of H1000. I ended up with about 3/4 MOA group at 200 yds with 2850 avg velocity.
For those curious about using a faster...
I can't speak to virgin brass as I have started with once fired brass from Gunwerks. I can speak to the changes I have seen. With my comparator the shoulder on the once fired brass from Gunwerks was 48.10mm and now after multiple firings I get a fired measurement from my gun chamber of 48.18...
I was not expecting the brass from another chamber to have similar readings. I was expecting that after 4 firings the the brass would not be .004 different from the first firing in my rifle (which is actually the 2nd firing on the brass). Not a huge deal, just curious if others had experienced...
I guess I either bump the brass to the "new" length or continue with what I have been using. I will at least test the "old" vs "new" length to see if any velocity or impact difference is significant.
Thanks for the reply. The brass I purchased was from once fired Gunwerks reportedly from the member here. I was all in good condition and all measurements were consistent for them before I started shooting them to form to my chamber.... trim and shoulder.
That is what I did. If my wording made it sound like it wasn't, my bad. I used the fire formed measurement from my gun to base my loads off of. I didn't think that twice fired brass would move much more but apparently it does, at least for this gun.
Loaded up some 7 PRC rounds with H1000 and 175 gr ABLR to test this weekend. Plus cleaning guns from this past weekend and cleaning more brass and getting it ready for the next cycle.
