Drew I ended up sending the AI barrel back... wasn't what I was looking for and I ended up just going with a vanilla 243.
I went and shot some milk jugs at 435 to see if they'd stabilize that far. Both the Retumbo and H4350 loads did just fine... I'm done worrying about 100 yard groups. It's not a custom barrel and I'm not a good enough shooter to blame anything on powders, barrels, or bullets.
Now, to chrony whichever I go with, and move on out. My dope from QL got me in the ballpark to shoot out to 435, but I'm gonna want to know what I'm running to air it out I think.
Tanner just a little advise. Retumbo is not 243 powder even with the heavies. I have a 6mm-284 that has quite a bit more case cap. than a 243 and it is still way too slow of a burn rate. RL22 is about as slow of a burn rate that is realistic, my favorite in the 243 with 95-105gr bullets is IMR4831. Right now on this forum many are gacking allover themselves that RL17 will do anything...it is a much better choice than Retumbo. VVN160,RL19,H4831, hell even JB's TAC that he claim's you will never need to clean for the life of the barrel is a better choice than Retumbo......you've been gettin bad advice
Retumbo is the powder of choice for the 243 Win in my little world. But then I would hardly be inclined to push the silly lil 243 Win as much of a gun.
Buy an MTM drop tube if you want that 243 Win to run with 105s.

I have all the sources. They can't stop the signal.
Swirling technique.. Tilt your funnel just a bit.. Pour the powder directly into the side of the funnel up high.. You should get a swirling of the power like water going down the drain.. If you don't get the swirling then you aren't doing it right.. Some say it works better than a drop tube, but I don't know as I have never used a drop tube..
Since part of this thread was cleaning, anyone used the outers electrolysis system to decopper a barrel?

I've got a commercial mauser action, beautifully figured Boyd's JRS stock that Karnis has just reshaped for me, and I'm hoping to put an 8- or 9"-twist 24" Douglas tube on it chambered to 6mm Rem. I've got a couple of those Burris FFIIs lying around and am going to send one in for the mods.
Thanks again; I'm excited to hear about your results here!
the Burris, while sporting some nice glass (at least in my small experience), could definetely beef up their turrets a bit. I haven't used it on the 243 yet cuz I set up the Bushnell on it, but you just have to really pay attention to what you're dialing in because the clicks are a bit mushy. That being said, for my intended purposes and the guy just looking to have some fun, I'm sure it'll turn out to be a great scope.

John, that is great you and a few others have got Retumbo to work in a 243, I have tried it in 243 6mmAI and 6-284 and always found a better powder for 95-115gr bullets. Every barrel is different and good luck with it if it works for you....
Alright guys... I got to shoot er at a little longer range today, went out to 530 and let er rip. But... I'm perplexed.
Checked my zero before I backed up, exactly 3 inches at 100, dead center. Backed up, and missed about 4 times. I went back up to my target, and I'd been shooting over it (I expected to be a little off, my velocity input in Shooter was just a ballpark guess.) So, I went back out, dialed my scope back down, and started nailing the gong.
Here is the weird part... I only needed 3.5 MOA of up to hit at 530 yards. WTF. That would mean my MV would be close to 3300 FPS I believe. Granted, I was shooting slightly downhill, but I still dont' think that would make this much of a difference. Shooter was telling me to dial a bunch more ele than I ended up needing.
Here's the info for the load/atmosphere: 105 AMAX- 49 gr Retumbo, CCI 250. COAL of 2.8
Man I know.. I'm gonna try to borrow a clock tomorrow. I think when I get my real velocities it'll shape up... But shooter shows 9+ MOA at 530, when I change the zero height to 0".
