    Just ordered a barrel for my savage 10 that I use for long range prone in crap weather. Sick of getting pounded by .308 recoil when the wind is high or when I'm out of .223 ammo ;) . Yep, I is a sissy that way. Anyway, ordered a 26" pipe in .243Win Ackley Improved from Columbia River Arms/Black Hole Weaponry. It's in an M24 profile with the muzzle threaded 5/8x24 as one might expect. It'll be a straight taper to .900 behind the muzzle threads. I decided I didn't want to get my .308 barrel in the coral snake pattern when I could have a much better chamber inside so decided to get the new barrel now. 3200FPS with 108gn ELD-M's without even pushing it hard. All the trajectory of a 7mag without the blast or recoil and barrel life should be pretty good considering the blazing speeds and overbore case thanks to a 40deg shoulder and polygonal rifling.

    Also found out I can use N550 and get some pretty spanky speeds. I'm thinking of doing a test load with US869 given the long barrel. A 100% load might just work with that long barrel.

    Took my .308 out for its last match with the .308 barrel on it. Man did that suck. I had to go to a hunting bullet due to stock on hand and then I found too many of my usual match brass were getting the shiny ring of death (incipient case head separation) so I culled the whole lot and went to a new batch of mixed fully sized and neck sized LC11 I had. Turned out it needed all full length sized and trimmed. 42 of the cases would feed at all, of 80 of them. I'd also decided to back down to human pressures to keep from having a case head separation during the match. That meant a new load, untested and undeveloped. I got to the range with about 30 minutes before the match start and had even tinkered with my scope rings to pull out 25MOA. So I had all of about 5 minutes to get some shots downrange, zero and double check all my fasteners. The SD's on the load was 46FPS across 5 shots EEEEK! It grouped over 4". Shit.

    The failures to chamber shredded me on time but didn't DQ me in any of the stages as I was able to get at least a couple shots off at each stage. I started out on stage 3 (meaning run 3-8 and then loop back for 1 & 2 to finish the match). My first stage out I hit 5 of 7 and flinched on the other 2 so I was really starting confidently. Misplaced confidence. Then the ammo problems started. The rest of the match was a disgrace. I managed to goose egg 2 stages completely and danced around the bulk of the targets missing usually by a bullet width to a couple inches.

    I didn't get the lowest score. Someone on my squad shooting a gen 1 RPR had his bolt shroud keep popping off and general gun problems and managed to shoot 4 of 8 stages before the gun problems became fatal to further shooting efforts on his part. He stayed with us though and didn't get a DQ, got a DNF which is subtly better. There were also a couple that just had bad days and shot lower scores because they weren't on their game like normal. I know those guys and they usually do very well but that day not so much.

    Stuff happens . I was at a match and foaming at the mouth , there was 22 steel targets plus a texas star . I just knew I was gonna smoke that stage , I started off one and done on each plate and popper target got to the star and fell apart . I had 6 magazines laying at my feet when the smoke cleared. I should of run the course in around 35-40 seconds but ended up with 90 seconds . the only thing left to do was laugh it off and move on .

    Might have to go to a single stack mag and maybe some ramp work to get the AI to feed 100%. Just went thru that whole ordeal on a Mod 12 223AI/6TCU. The AICS style single stackers feed AI good, the stagger feeds are yukky, shoulders will hit the sides of the ramps and bounce all over.

    6 Dasher woulda been good too. Sometimes takes a little mag massaging though.

    It's in an LSS chassis with AI single stack 10rd mags thankfully. I was hoping someone would bring that up in general though. I'm curious about how the feed ramp will deal with the 40deg shoulder. Don't know if I'll get bullet noses jamming between the breech face and the receiver wall. I get that problem when single feeding in my MVP and occasionally with my 7BR. The MVP really prefers feeding from the mag. My 7BR has a single shot sled bedded in but the short COAL and push feed bolt face allow rounds to get a bit cattywompus now and then.

    As a cheaper alternative the MDT polymer AICS style mags ain't bad for the price, only issue is tweaking them is permanent and a little tricky.

    There are 6BR follower and spacer kits for AICS metal mags out now supposed to solve the feed issues 100%. Some people report no issues with std 6BR and 308 mags, BRX/Dasher can be problematic.

    BTW do not recommend CDi bottom metal for a Savage unless its a really low profile stock, their pillar and trigger guard height is recockulously short.

    only 2-4 weeks to go before the new barrel arrives and promptly heads out to cerakote-ing.
