I have one in .308 Win and probably should have gone with the 6.5 Creed.
Mine is about 4 ounces heaver than advertised.
I went with a heavier optic, but that was always the plan.
My goal was 8.5 lbs or less suppressed, and I chose .308 Win because my suppressor is .30 Cal. I beat that in spades, but I'd have probably been better off with the CA Mesa FFT. I was lured by the price, I got the SL for just under $900 after shipping and FFL fees.
I've shot 125 to 168 grain bullets in mine, suppressed the recoil is manageable and it's quite sharp without it. Especially with anything over 150 grains. I actually gave up shooting it unsuppressed, it just wasnt any fun from the bench.
The issues I've noticed with my rifle.
Accuracy, yes it will print a group for 3 shots measuring MOA or less with factory ammunition. It will not print the next 3 shots on top of the previous group, after letting the rifle cool completely. It also usually throws the first cold bore shot, and settles in after. On a good day behind the trigger I'm at 1.5 MOA for 5 or more shots, usually closer to 2.25 MOA. The rifle seems to like 168 grain SMK and Horn HPBT bullets the best and that's what I shoot the best.
There is no extra room in the magazine. Howa shortened the 1500 action on this rifle to reduce weight, I can't load a round longer than 2.8" and feed. Think Remington model 7, so IMO 6.5 Creedmoor will be a better fit than the .260 Rem. Plus I think you'd have to rebarrel to do it, as a .260 reamer won't clean up a Creedmoor chamber because of body taper.
Feeding is hit or miss. The rifle feeds flawless with dummy cartridges. Under recoil I can't always pick the next round up from the magazine. Thats with slow deliberate fire as well as rapid cycling of the bolt. I don't think the spring retention is enough to keep the mag in the proper position 100% of the time. Pushing up on the magazine fixes the issue. It will usually fail to pick up any of the 3 rounds from the mag, so running it 3+1 rounds, 3 rounds from the mag only, or 2 rounds only doesn't make a difference on feeding reliability.
Polymer bottom metal, magazine, with screws weighs 2.8 ounces, so it is extremely light. I'm torquing to 35 in-lbs on the front screw, and that makes me worried I'll crack it as it is extremely thin. I've contacted OG, JO, and DIP and there are no plans to build an alloy bottom metal like they do for the Mini action at this time. This would IMO fix my feeding issues having alloy BM with an internal magazine.
Ejection, as the rifle just dribbles the cartridges out. It doesn't fail to extract, but the cartridge barely clears the port. I've tried removing and cleaning the ejector, but it doesn't help. It'll take a stiffer spring to fix and I haven't ordered any.
Forend flex, it's an extremely petite and light stock. Even though it is carbon fiber there is a good amout of flex. Anything attached to the forend will more than likely introduce a POI shift from POA, especially if attached to the sling stud.
I do think the rifle has potential, and that I need to learn to shoot it better. If I can get fix feeding issues and get it to eject better it'll make a solid hunting rifle on game inside of 400 yards. Jefferson Outdoors was the only company that said they might in the future build a bottom metal for the rifle.
That said, I'm debating sending the rifle back to Leagacy. Just for the feeding and ejection issues, but I'm not sure it'll do any good. It meets their accuracy guarantee, so they may say it's good to go.
