I've got a butt load of Federal 224 Valkyrie ammo if anyone is interested

SGC's original LA9, had some initial problems as it used a plunger-type ejector that chucked the short 9mm case out too soon unless you really worked the action fast. That model has been discontinued, but in 2020 they launched the new 9mm LAR, which is much improved in terms of reliability. There's a video on YouTube (gunmart tv) that shows it in action (21 dec 2020) and another on the 15 Jan 21 showing more detail. Really nice piece of kit and works well. Enjoy

308 ARs tend to be a bit on the heavy and potentially big side and being a hybrid system you can experience issues with primary extraction (unsticking the case from the chamber) an issue exacerbated by ammunition quality, or the lack of it. Yes Valkyrie does some good work, but I'd also say speak to Southern Gun Co too, as they have probably made more AR10-types than any other and have the most experience. Not sure if they still exist, but you could also see if anyone brings in LMT who made the Civilian Version of L129A1TM MOD “Sharpshooter” rifle. Shot that and it works pretty well, try firingsolutions.co.uk.

Interesting I had an original P7, what a sweet pistol

Anybody got any data for reloading the 17 Hornet with Hornady 15.5-grain NTX BULLETS?

I bought a T1x MTR last year and really like it, as an ex CZ452 owner I think they are about on par. but I prefer the T1's magazine and safety catch systems. The LOP is rather short and I fitted the extension kit and a rubber recoil pad as the original is smooth plastic and gives no shoulder adhesion. Also added the forend adaptor that widens and flattens the grip and the expanded pistol grip too. Plus a Kalix Teknik adjustable comb kit. All improve shootability, but on the downside they add a chunk of money and in truth Tikka should have put more effort into the stock design at factory, as it's pretty basic for what is otherwise a good rifle. Might have been better off looking for a second hand T1/T3 GRS Berserk or Bifrost.

I have two Bifrosts, one on my Remy 700 and the other on my Tikka T1x and really like them, the fully adjustable butt is good, but the offset pistol grip is superb. However, both had a strange quirk when you first torque them down, as you're winding the bolts in, suddenly there's a sharp crack. Both times, I stopped and took it off and looked for something broken, but nothing and no problems shooting after. Go figure.

Like all of the above wise men said, take it off, it only takes second to put it back on again... as the alternative is not worth thinking about.

22 semi's can be fussy, I found the best sub-sonic ammo for reliability was Winchester's 42-grain MAX, that extra 2-grains of weight, seems to give a bit more cycling reliability.

Pile of chod, everyone seems to feel they need to offer some form of military look-a-like these days and as you said the R1 is a very bad investment. Anschutz did the same thing with their 'dynamic shooting' semi- based on the awful ISSC copy of the FN SCAR, terrible...

HMR is a super cartridge, mine a Ruger M77/17 All-Weather (stainless heavy barrel) can head shoot out to 200 yards on a fine day, but is not so clever in the wind, that's just the way it is. If I was moving up then it would be the 17 Hornet, as that is a little peach; fast, flat-shooting and good accuracy potential.

I've got one, I've used it for boar shooting for many years, the only problem is that the illumination doesn't work and Zeiss UK did not seem interested in repairing it, apart from that it's 100% and a great little scope for up close and personal, that can also reach out to well over 100 yards.

Blimey, someone else who owns a Grendel, don't you just love them? Mine's on a CZ527 action with a Pacnor stainless tube at 22". I do have occasional feed issues and tend to load four and not five rounds, but for a light and effective, mid-range small/medium deer and fox rifle its sweet. I run mine on Nosler 100-grain Partitions and Viht N530 powder.

The R1 is not that good and the Kriss is quirky and a bugger to cock until you know how to do it, even then it's no AR in terms of shootability. Have not shot an SGC or a CMMG in a long time, so I reckon it's the Tippman. However, and put your hate of plastic on hold for a moment, the S&W 15/22 is quite some rifle, I've had one for 8-years and it's all tricked up: Cerkote FDE finish, Magpul furniture, etc, etc and it's a shooter. Very reliable and a good little rabbit basher, with Winchester 42-grain MAX subs, even out to 100 yards for body shots, plus great fun as a plinker and it scratches an itch as I come from the time before the SLR ban.
