baldie Posted March 12, 2018 Author Report Share Posted March 12, 2018 Managed to stick 25 rounds down it last weekend. After the barrel had broke in, the groups started shrinking. This one was half way up a load range, and produced 3150 fps with an ES of 10. All loads, right up to .1 over max gave no problems at all with extraction. Recoil felt less than a .223, and these speeds were with a 70 grain Nosler RDF. Having done all that brass prep to the cases, I didn't expect them to be stunning whilst fire forming, but I would live with regular .4" groups out of an AR....especially at those speeds. I feel better is yet to come on the 2nd firing. Hopefully, brass won't be too long now. Link to comment Share on other sites More sharing options...
The Gun Pimp Posted March 12, 2018 Report Share Posted March 12, 2018 Where's the brass coming from Dave? I've been looking to get some myself. Link to comment Share on other sites More sharing options...
baldie Posted March 13, 2018 Author Report Share Posted March 13, 2018 I had to make it Vince, from 6.8SPC and a modified die. I think the first place it will appear, will be Brownells. Link to comment Share on other sites More sharing options...

Hobbit Posted April 14, 2018 Report Share Posted April 14, 2018 looks interesting - barrel length/MV relationship a lot more linear than usual Would 224 valkyrie in an AR be legal in a CSR match or must it be 5.56/223 rem? Thanks Link to comment Share on other sites More sharing options...

Thanks It would be legal in Practical Optic class, but not in Service Optic. Remember that the maximum permitted MV on MOD gallery ranges is 1000m/s (3280 fps), so be careful not to exceed this if using lighter bullets.

baldie Posted November 1, 2018 Author Report Share Posted November 1, 2018 An update on the Valkyrie. A long and tortuous path. ? After several range visits, I concluded the 6.8 SPC brass was simply not good enough, and shelved the gun. Then good old Gavin at Brownells, let me know some Starline brass was inbound, so I had 500 cases. This made a big difference, and we experimented with various powders, most of which were just not quite right. I beat the cfe223 to death [probarbly because I have 10 tubs of it ] ? The yanks keep on about it, but no matter what i did with it, the ES spreads [and groups ] were not great. Tried a variety of bullets, mainly nosler RDF's in 70 grain and 85 flavour, and got good speeds and accuracy with the 77SMK. Then Adam at Sassen, asked if I would test them a new cut rifled blank in .224. So on went a 1 in 6.5" twist at 24" this time, so I could see what an extra 4" difference made. Surprisingly...not a lot in speed terms. The new sassen cut rifled blanks are something else. The bore is like a mirror. These patches show what came out, after 100 rds. The last patch had sweets on, and was left to soak . No copper whatsoever. The cartridge is a pernickety little swine, and only likes certain powders, but it seems to handle various bullet weights well. I found the RDF's definately have a sweet spot, at 0.040" back, and I suspect , 0.050" will be even better. Despite my crap bench technique, I have had some satisfactory results now, with two loads shooting around 0.4" . I think to wring the last out of it, it would need to be bench rested. AR's , off a bipod on a concrete bench , are like a roller skating pig. Speeds ? 2850 with an 85 grain, and 3050 with a 77. Couple that with perfect extraction, and you have a very marked improvement over a .223. The BC's of the 85 RDF's are huge, compared to a SMK, and that translates into less drop, and a lot less wind drift. I have a fat box of sierra 90 grain matchings come today, so will give these a whirl too. Many thanks to Adam and James at Sassen, for their help on this project. A beautiful barrel that just works. I will now see how it fares in next years Practical class at Diggle. Link to comment Share on other sites More sharing options...
baldie Posted November 13, 2018 Author Report Share Posted November 13, 2018 Hopefully going to test the 90 grain SMK this week. Other news is that I have some 6.8SPC bolt heads for the Bighorn actions on their way. Those, coupled with my BR converted mags will make a top end bolt gun possible. I was having this conversation the other day, when a friend asked ...Why ? Why not use a 22br etc ? Recoil. There is a fair bit less, giving faster target re acquisition . The valkyrie reamer will handle the 90 grain bullets without throating too. Having done all this testing on an AR, i'm fairly certain a bit more could be wrung out of a bolt gun.

Andrew Posted November 17, 2018 Report Share Posted November 17, 2018 It will end up getting better. A stunning development with thr Valkyrie here is that the inexpensive ($11/20) Federal American Eagle 75 grain FMJ will shoot ridiculously small groups from AR's. Better or equal to the heavier match loads. Valkyrie ammo and components are now available and inexpensive here. I wonder when that will materialize for UK shooters?~Andrew Link to comment Share on other sites More sharing options...

Anything remotely exciting and gaining traction/popularity Stateside means the importers & distributors here will instantly bump prices up 50%. I can already see them rubbing their grubby hands with glee at the prospect. Link to comment Share on other sites More sharing options...

Scrumbag Posted February 4, 2019 Report Share Posted February 4, 2019 Baldie, would this go into a CZ527? Scrummy Link to comment Share on other sites More sharing options...
baldie Posted February 5, 2019 Author Report Share Posted February 5, 2019 It will go in anything that a 6.8 SPC bolt/head can be had for. I'm going to open out a Tikka at some point for a demonstrator. Link to comment Share on other sites More sharing options...
baldie Posted February 9, 2019 Author Report Share Posted February 9, 2019 First time out today at Diggle. A truly horrendous day with winds gusting up to 45 MPH. It was too windy to use hand held targets, so we rigged up our electronic targets and shot the 300 yards match. Had I not been too slow on the 2 x 5rd stages, i would have shot a perfect score 10 wash 9 wash 10 wash. The cartridge took half the wind of the .223's and 6.5's....it proper hammered them. Well worth the last 12 months of experiments, and the bolt gun will be even better. Link to comment Share on other sites More sharing options...

I can appreciate things cost more in the UK but I think that is ridiculous... Scrummy Link to comment Share on other sites More sharing options...
