Seattle. Shoot at the Seattle Police Athletic Association (SPAA) Happy New Year!

" ...sweet spot at 53 grains under a 300 gr Hornady pill..." Going over and logging my data into the book noticed it was actually 55 gr Varget, but highly unlikely anyone is going to be relying on a 308AR forum for obsolete cartridge data anyway...

It's a fun process if you are in no hurry. Month's worth of work spread out over several years. Thanks for the kudos.

Been a work in progress, 7-8 years or so. Started with basically no wood, my dad did the furniture from scratch, bore was in great shape, rest of metal not bad. Old local smith did the finish. .223, .308, .405, 45-70

Took my "Good Medicine For Lions" 405 cal '95 Winchester to the range today, been trying to get a decent load for it over the last couple months, hadd spreads close to 100 FPS with H4895, over 60 spread with factory loads, tried Varget today, sweet spot at 53 grains under a 300 gr Hornady pill got a SD of less then 4! Managed shoot a couple of 100 yard groups that rivaled the scoped gun next to me, wind blowing rain sideways kind of a an equalizing force! 405 Winchester M1895 1929 build. 300 gr pill over 53gr Varget Truly a gun that earned the "Punishes at both ends" title.

OK, Range report Started with the Seekins adjustable block closed, wanted to see how much extraction force was required for a couple different rounds, seemed about right but nothing to really compare to. They extracted without too much force. for future may be a good way to judge chamber pressure. Then using some wimpy loads, took it out about 3-1/4 turns to get it to cycle and just lock back. took it out another 1/2 turn for good measure. Then ran a couple hundred rounds through it, 2800 fps 150 gr bullets AR Comp powder, 180 gr RL-15 hunting loads, 180 gr AR Comp loads, bunch of misc BL-C2 and Varget loads from earlier testing. Cycled flawlessly over the entire range of loads. Brass stacked up in piles varying from 11:00 to 5:00 depending on load. Wimp loads stacked up on the shooting bench. Shot over a couple hundred rounds, Re-lubed BCG after first 100 rounds. Now ready to start tuning rifle and loads for accuracy.

Month and a half or so not too bad wasn't expecting miracles. Took about the same or more for the Leupold I sent back, busy time of year. Probably won't get back to the range till next year, hunting season, vacation, holidays. Have to have a little patience, but definitely taking all the rifles out while its still cold to get some chronograph data in winter temps. The Strelok Pro lets you enter several temp/velocity pairs for ea round, uses it for fine tuning the dope table based on current conditions. Think I can do that with the BDX stuff also.

Not only no FFL required, but new rifle didn't even come with signature required. Sitting on front porch when I got home yesterday. Brand new lower and complete upper, including barrel and newer design floating handguard (longer barrel nut and more clamping surface, 3 screws instead of 2). Still a DPMS based recoil, however before I replaced it with the longer tube out of curiosity I pulled the spring, dropped the buffer and BCG back into the tube, and clearance looked good, wasn't ramming into the ears anyway like last one. Got to say, Anderson making every effort to make good. 12.06 gas tube looks to be positioned correctly. Completely disassembled and mostly back together last night, still need to fit the Aero bolt catch, put the M4-72 brake on (How to get the old locktight out of the threads?) , mount the new Sig Sauer BDX scope and a few rail accessories.

Got the email from Anderson, gun is on the way back, should have it in my hands next week. No FFL

the Barnes X claimes a BC of .432 but if I use the 0, 20, and 80 yard average from the Labradar and the 100-200 yard drop I get a bit less, so I used that number in the ballistic calculator. Need to do some further testing at longer range to confirm. Then all I need is a lot of luck, and a cooperative critter...

Not sure if there is a autoloading sporter shooting a heavier caliber.

They shoot clean, Browning spent a good bit of their design budget on making a gas system 1000% trouble free.

Elk gun. After all the autos we picked up a Sharps today, shooting consistent 9 rings and clipping the bull at 100 yards, (until our shoulders turned black and blue) better then the group next to us with scoped black guns at the 50 yard berm. Never shot a set trigger before, you're about halfway through thinking about squeezing and the bullet has left the barrel...

Like having a spotting scope right on the rifle. What can I say, my eyes ain't what they use to be. We have a similar weight scope/ mount / rings on a 300 Weatherby Mag been holding zero for 70-80 rounds so I am optimistic this will work out. Not like you would want to shoot 100 rounds a week out of one of these anyway...

New optics on my (B)AR, not a 308 and not an AR. BUT, cool rifle nonetheless. 338 Win Mag / Viper 6-24 x 50 HS-T Alignment and lapping the new rings Found a set of mounts with an offset rear, perfect fit for the Vortex Medium ring height Off to the range this weekend. Should be an upgrade from the Leupold VXII 3-9 x 40 Kevin Knight's brake job. Lots of practice makes perfect!

Welcome from South Park How do you want to build, ground up, buy a complete rifle and add a few mods, or somewhere in between ?

PITA all aftermarket parts removed and stock reinstalled

Earlier in the thread we were discussing 11.75 gas tube vs 12.06 gas tube I think I asked where the round was when the gas tube cleared the gas key answer was somewhere down range/ how much pressure was left in the gas tube answer was none. Also discussed short tube caused timing issues. Trying to understand why timing is affected if no pressure left when tube and key disconnect. Thanks Al

So back to gas tube length... If the tube does not clear the end of the gas key until after pressure drops to relative zero with the correct length tube, as discussed earlier, does it clear the end of the key prior to relative zero pressure if it it 1/4" too short? Is that what causes the timing issue?
