Not much of a long range load, but I'll conjure up something with the 105 A-Max as far as that goes. Going to have this rifle punched AI eventually, just need to figure out when. No pressure signs whatsoever. Safely worked up to 46 grains of '17 thus far, might see how far I can push it for the sake of curiosity. Hunted with this rifle shooting 45 grains of '17, which pushed the 80 grain bullet around 3350 fps. I can vouch that the deer did not appreciate this load in the least. Accuracy was there, too. Shot two groups at 100 yards in haste after getting it on paper before the season. First was off a pretty unsteady rest and was 5/8" center to center. Second group was a CH larger than 1/4". I highly doubt that I'll be able to replicate the 1/4" group, but I'm not going to complain. Here's what Quickload shows. I just got the program last week, so if there's anything I messed up on, please let me know. Wasn't sure on your barrel length, so I inputed a nice average of 23 inches. Cartridge : .243 Win.

Figured that load was very likely near maximum in that rifle, and it appears that it is from your QuickLoad data. I should probably go ahead and get a copy of that. Going to load up some more TTSX's with 45 grains of '17 and reevaluate everything. Once we get warmer weather, I will be sure to ascertain as to whether or not this load is safe in higher ambient temps. As someone mentioned, Barnes lists a maximum in their book as 45.5 grains and that is the data that I used to work up to that load. The QuickLoad data with 45.0 gr RL-17 is spot on with my empirical results. prairie goat - FWIW, my rifle has a 24" barrel and the COAL was 2.755", would be curious to see if that changes the QL data by much or at all.

After reading this thread, keepin it a 243 vanilla wouldn't be near as much fun as converting to the A.I. version...

Not worth the cost and time for 100 fps. Won't see any difference in the field. Trimming is about eliminated. Big whoop. If you are rebarreling, go for it.

If you are rebarreling, go for it. I'm in support of this as well. If this barrel hadn't ALREADY been punched AI, I wouldn't have gone that route. But, it was so that was just an added bonus. As far as I'm concerned, a vanilla 243 will drive the 80s to 3350(ish), and the 105s a bit under 3100. That's a lot of smack from 45-49gr of powder.

prairie_goat Campfire Outfitter P Joined: Jan 2009 Posts: 8,896 Montana	Yeah, it's one of those deals that seemed like a good idea at the time, and later I kinda scratched my head and asked myself "why did I do this"? It was about this time of year, 11 years past that I sent in a Sendero 25-06 and a KS mountain rifle 280 and had them punched AI. Had some fun with them, but I didn't gain anything - and spent at least 400 bucks getting them both set up as Ackleys by the time the gunsmith was payed, rifles shipped, and new dies were bought. Like I said, worth doing if you need a new barrel anyway, and if you're not set up to load for the rifle in the first place.

I will say that if you've got a gunsmith buddy that'll punch it out for a 6 pack or whatever, then it'd be a good idea. But, there are a few benefits to doing it besides the new chamber... Jordan had his throated in accordance with his 105s when his was punched out (I believe?), and that's a huge part of this 243 AI and 700 action equation... I think it's almost time for me to order up a Douglas for this rig
