Hello all,

Trying to decide on either the 6x47 lapua, or the 243 ackley. Primary use will be long range target and coyote. Plan on shooting bullets in the 105-107 grain range. Please feel free to add any positives or negatives of either cartridge.

Thanks in advance,

Tony

I've shot both .243 and 6XC, obviously similar to your cartridges-in-question. Both are great, velocity edge would be with the Ackley I believe - see cartridge info on home page. .243 Ack. info is on the .243 cartridge heading. 6XC info is applicable to 6x47 L.

i was in your shoes once. i say go for it either way. i went 6x47L cuz it can do everything the 243ai can with less powder and has a slightly better accuracy potential due to its case design. i really wanted the 243ai and had tons of brass, but i'm glad i went 6x47L and would do it again.

I love my 243 AI 's. I also own a 6x47L.

Both great rounds. Both shoot the high BC bullets well. Lapua is getting easier to find....

the thing i love about the 243 AI is if you ever go on a trip and forget ammo, you can still shoot factory 243 rounds with great accuracy and then have fire formed brass.

Great way to not ruin a hunting trip.. (ask me how I know) LOL

sent ya a email too.

Out of interest what kind of velocity do you get with the 6x47's?

I have a .243ai which i get 3140 with both 100gr gamekings and 87gr vmax's

Thanks so much for the info so far. I really appreciate the knowlege found on this sight. A few more questions, what is the case capacity of the two cartridges in question, and are they similar in velocity when loaded to max. From what I understand the 6x47 is more efficient and can match the ackleys performance with less powder.

I shoot the 105 in both rifles.

6x47 is 3157 fps at 4695 asl 40.7 grains H4350 7.5 Twist

243 AI is 3320 fps 45.5 grains H100V 7.75 Twist

I also shoot both cartridges.

6X47L=38.5 Gr's. H-4350, & 105's= 3050fps.
243AI=47.5 Gr's. H4831Sc, & 107SMK's= 3230fps.

I can get over 3100 fps with the 6X47 but accuracy diminishes.
