Gungrinner Posted November 2, 2019 Report Share Posted November 2, 2019 After many hours of research, deliberation and cogitation I have managed to find an action for my .223 build. I hope to use the rifle for 300,600 and 800, 1000 when the conditions allow. Action has been delivered to my rfd and the barrel is on order. The waiting game begins!! (could be a long wait but in or around Christmas would be nice) Barrel spec Sassen button rifle 28" screw cut 1-7 ( I want to use the heavy Berger bullets) Throat to suit long bullets More build info to come Quote Link to comment Share on other sites More sharing options...
Re-Pete Posted November 2, 2019 Report Share Posted November 2, 2019 My 223 is a Tikka M595 with a 30" 8 twist barrel.............good fun at 1000 with 26 grains RS52 and 80 grain SMK's or JLK's on a calm day........... Pete Quote Link to comment Share on other sites More sharing options...

geek Posted December 28, 2019 Report Share Posted December 28, 2019 What made you choose the Onyx chassis, over the other MDT Chassis systems; weight? Quote Link to comment Share on other sites More sharing options...

Woodlander Posted January 4, 2020 Report Share Posted January 4, 2020 Be interested in how it shoots. Will you get it cerakoted? Why did you choose a buttoned barrel? Quote Link to comment Share on other sites More sharing options...

Why did you choose a buttoned barrel? I was advised the barrels where good value and from a British company. Leaving barrel bead blasted for now but could refinish later on. I hope to keep updating post with load dev when I get the rifle. Quote Link to comment Share on other sites More sharing options...
Ronin Posted January 5, 2020 Report Share Posted January 5, 2020 How does one set the barrel bore to run at zero run out in a three jaw Chuck prior to any machining ? Quote Link to comment Share on other sites More sharing options...
Gungrinner Posted January 5, 2020 Author Report Share Posted January 5, 2020 An expensive machine is my guess😛 Quote Link to comment Share on other sites More sharing options...
JR FIREARMS Posted January 5, 2020 Report Share Posted January 5, 2020 My 3 jaws are adjust-true chucks, they have an integral spider so they can be adjusted for runout. I have some runout videos on my facebook page, take a look. 👍🏻 Quote Link to comment Share on other sites More sharing options...
Ronin Posted January 5, 2020 Report Share Posted January 5, 2020 No problem, I didnt see the Set Tru ajustment in the image, thanks for clearing it up, the six jaw Set Tru is sublime to use Afraid I do not trust "social media" so have no face book Quote Link to comment Share on other sites More sharing options...
JR FIREARMS Posted January 5, 2020 Report Share Posted January 5, 2020 They are much nicer than a 4 jaw. I’d like to get a 6 jaw version, but the 3 jaw on the colchester was a bargain, and the Haas came with one luckily. I don’t blame you. I only use it for business purposes these days.

Gungrinner Posted January 10, 2020 Author Report Share Posted January 10, 2020 Completion date received so in preparation I have purchased some plinking ammo and loaded some testers. 62grn federal 80grn eld match in starline brass with n140. (seating depth to be sorted when I get my hands on the rifle) Quote Link to comment Share on other sites More sharing options...
stephentri Posted January 10, 2020 Report Share Posted January 10, 2020 Looking good, what powder are you using. Quote Link to comment Share on other sites More sharing options...
Gungrinner Posted January 10, 2020 Author Report Share Posted January 10, 2020 N140 as it's the only suitable powder I can get locally. Quote Link to comment Share on other sites More sharing options...
Gungrinner Posted February 13, 2020 Author Report Share Posted February 13, 2020 Had the rifle a few weeks now and managed to do some load testing at Bisley Siberia yesterday. Found a good node that should get to 1000 yrds at 1300fps. Happy days. hopefully stretch its legs later this month at 300 and 600. Quote Link to comment Share on other sites More sharing options...

Re-Pete Posted February 15, 2020 Report Share Posted February 15, 2020 That's an MV of approx 3200 fps with an 80 grain bullet...............can I ask what powder/bullet you're using to get that? Pete Quote Link to comment Share on other sites More sharing options...
Re-Pete Posted February 15, 2020 Report Share Posted February 15, 2020 OK, I started at the beginning this time 😁 How did you arrive at a speed of 1300 fps at 1000 yds with N140? I ran this through Quickload, assuming a 100% fill, and it didn't get anywhere near. I'm interested because I have a 223 M595 with a 30" barrel, and I've had a lot of fun shooting it at 1000yds. I use RS52 powder which gives me an MV of 3050 with an 80 grain SMK, just about supersonic at 1000yds on a good day. Pete Quote Link to comment Share on other sites More sharing options...
