762 ULTRAMAGA
WKR
My wife has been hunting with my shorty 6.5 saum ultralight the past few seasons and really hates shooting it. Last year she missed an easy shot at a good buck due to flinching.
I decided to design her a 6mm magnum wildcat for short barreled suppressed hunting with the goal of getting her to shoot more.
I like the concept of the 6 prc but it's a little too much for what I'm wanting, and I really dislike short case necks.
Sooo I shortened that baby down, lengthened the neck, and blew the shoulder out to 40 degrees.
Meet the 6 Short Action Suppressed (6 SAS). My inspiration was the 6 BRA, the long neck allows for throating heavy for caliber bullets (like the 115 vldh) above the neck shoulder junction, while also leaving plenty of neck to run 105 or 108s close to the lands with plenty of neck to capture the short bearing surface.
I've also found that short fat cases tune extremely well and single digit SDs are effortless.
I've only recently received my barrel back from Karl at Kampfeld Customs, and just started fireforming cases last weekend.
I went with an 18" Rock Creek barrel that finishes .730 at the muzzle, it's built on a Tikka action in an XLR element 4.0 SA chassis.
So far fire forming loads with 115 Berger VLDH bullets are clocking 2900 with an SD of 8 using 51 grns H4831SC. I'm shooting clover leaf groups and went 7 for 7 on an 8" gong at 550 the other day.
Fast forward 3 days and I've made my first kill, a solid buck at a whopping 50 yards.. I purposely put the 115 vldh in the shoulder to see how it'd penetrate at close range, I'm impressed!
It blew through both shoulders, shredded the lungs/heart, and lodged in the offside skin.
The recovered bullet weighed 55 grains for anyone that cares, the buck literally dropped dead in his tracks.
I've never seen a deer die that fast, for some reason they almost always run 30 to 100 yards with perfect shot placement in my experience.
Here's a few pics of the case compared to the 6.5 prc, sized down, then fire formed.
Cartridge OAL is 2.810 with the 115 seated where it should be.
