F-Open build - 7KWS - What is it?

This particular build has been a long time in the making. I commenced this project in 2020 and only now have the finishing touches come together. The stock is a Cerus XR and to my knowledge, the only one in Australia. The stock is fitted with a RAD system and adjustable cheekpiece. Barrel is a Maddco, 7mm, 8 twist, 6 groove finished at 32". Tuner is a Dan Bramley tuner. Action is a Borden BRMXD, left bolt, right feed, left eject like my other Bordens. Trigger is a Triggertech Diamond. Scope is a March HM 10-60x56 sitting in a set of Gen III March rings. Calibre is a 7KWS, basically a 7SAUM improved made with a custom reamer and requires custom dies. I am yet to commence fireforming so I can't comment on load development/accuracy at this stage - further videos to follow showcasing hopefully what it can do...Thanks for watching! Latest Update 1 October 2022: Load development is looking promising. I decided to test CCI BR2 primers against S&B magnum primers. Powder was Reloader 23, brass ADG, bullet is a Berger 190gr hybrid. The S&B primer won with a nice node between 56.8gr and 57.2gr. 56.8gr averaged 2850fps with an ES of 9 and SD of 3.9. 57gr was better, averaging 2860fps with an ES of 5 and SD of 2.2. 57.2gr averaged 2865fps with an ES of 8 and SD of 3.3, so the 57gr charge is definitely the sweet spot. Next will be seating depth and tuner adjustments...
