Hammer Bullets in the STW

[JakeWes]

Hello everyone, I am new to the forum. Last year, I purchased a new RemArms 700 in 7mm rem mag on sale from MidwayUSA to build my stw. I stripped the action and installed a short chambered barrel from Shaw.

Here are the specs:
RemArms 700 action
Shaw Remington Magnum contour 7mm STW 26" 1-8
HS Precision stock, bedded
Triggertech primary trigger
Leupold bases
Vortex Pro rings
Arken EPL 4 4-16

I built this rifle to use Hammer Bullets, specifically the 172gr Absolute Hammers. Since then, I have used many different types of bullets, and here are my results.

172gr Absolute Hammer

140gr Absolute Hammer

160gr Shock Hammer

The 160gr Shock Hammers are by far my favorite because they produce almost 4000 ft/lbs of muzzle energy, just barely enough for rock chucks .

5 shots on the left are the 140gr AH and the 5 on the right are factory 160gr Nosler Accubonds.

Here is a video of me producing the 160gr Nosler Accubond group on the right. I only fired three in the video and once I saw how well they grouped I fired 2 more.

The 130gr Absolutes do 3700+fps in my 28" barreled 7stw and 1/2" @ 100yds.....

Try a bit more neck tension on the hammers or use a lee FCD to incrementally crimp 1/8 turn at a time and those hammer groups will tighten up.
All great groups there but hammers like a bit more neck tension
