Why don't you go to the 22 Dasher. 6 BR necked down and blown forward. 80 grains at 3400 and is a top 600 comp cartridge. Dies are available, great brass and easy to do. Go to www.6mmbr.com and look at James Phillips gun under "Guns of the Week".

The dasher is great , it will get 22-250 ackley speed with less powder. The question about barrel life in a 22-6mm would be anything past 400 round consider rechambering. My 22-243 ackley opened up from the.2's [img]/ubbthreads/images/graemlins/cool.gif[/img] to 3/4 moa at 400 rounds so she got rechambered and is shooting great again. I rechamber when heavy fire cracking starts way before the rifleing is gone. Good grouper i love many cals but compare the b.c of 22-243 ackley with 80 a-max at 3600fps and 243 ackley with 105 a-max at 3300 fps and the 22 cal is kicking ass at a 1000 yards. Yes the 6mm has better barrel life but what is free in this sport. I believe every caliber has its place. Its just matching the right b.c bullet weight with how much powder to meet the speed ,wind bucking, and energy requirement you need. [img]/ubbthreads/images/graemlins/cool.gif[/img]

Reed,

You picked a high bc bullet for the 22 and a mid range bullet for the 6mm. Run a 95 grain berger VLD at 3400 from that 243 AI and see what you get. Or better yet, look at a 115 dtac at 3100. It drops more but will edge the 22 in the areas that count. And then there is all that RPM against design specs cancelling out inherent accuracies and on and on.

I can still hit smaller target easier and farther away with my 6br fast twist than I can with my 22-250 AI fast twist and a lot of that has to do with bullet spin/accuracy and better wind drift with the six. Tain't lyin. Go look at some 1k br equipment lists in the back of the NBRSA news or PS magazine. More 6's in there than 22's by a looooong shot! But I agree with you that the 22's are just dang fun. One of my favorite things to do is show up at a long range fun shoot and whip out the 22 and hang with or beat some of the boys using 300 whizbang mags. The look on their faces when you tell them it's a 22 is priceless. [img]/ubbthreads/images/graemlins/wink.gif[/img]

Replacing barrel's after 400 rounds does'nt allow a guy to do much load development,after trying 2-3 powders and bullets for the best load combination?
Hoping to get a bit longer barrel life with frequent cleaning,ridding of carbon deposits,and more importantly,not allowing the barrel to get hot from too many sucsessive shots.
How much difference in barrel life could a guy expect to see between a .22 and 6mm?
Not worried so much about throat life,more so in the pursuit of consistant accuracy at 4-5-600 yards hunting varmints.

I have a.224 Vais with a 14 twist barrel,built on a Rem 700 action,so I've got the die's, had the bolt face opened up for it,that's why I'm leaning towards that choice,do a re-barrel with a 8 twist and go with the 80 grain bullets.

I would'nt hesitate to go with a 6mm if I was comvinced it was clearly the better choice.I'd give the 6mm-Vais a go.

Planning on making my next build a 6-284 using 105-107 bullets.

Thanks again Fella's for your input.

The 6-284 isn't going to be any easier on barrels than the 22-6mm or 22-243 ackley. If you want barrel life go with the 22 dasher 22 br or 6 dasher 6br 6x47 laupa or maybe 243 ackley. My 22-243 ackley was not shot out at 400 rounds just had coppering and fire cracking. I could of let it go another few hundred rounds but accuracy is everything in this game. Anything to fast flat and bucks the wind well is hard on barrels. Look most 1000 yard benchrest shooters rebarrel 6.5-284s at around 1000 rounds. Are they shot out, no. they just won't shoot the 4-6 inch groups they once could have done. I now one 1000 yard shooter that rebarrels his 300 wsm's every 500 rounds. After that he says they loose there winning edge. Still his barrels at 500 rounds are better that most barrels that people will ever have. Than on the flip side I say one guy shoot a heavy gun 300 win mag with 2000 plus rounds and compete and win. Just some food for thought

I know a bunch of you will [img]/ubbthreads/images/graemlins/frown.gif[/img] on this but a .223 wssm works great for me with 90 SMKs. I use 46.5 grs of Ramshot Mag. with a velocity of 3050 fps. Its very accurate. The barrel is 26" 1 in 8 twist and has no problem stabilizing the 90 SMK. A lot of people do not like the wssm brass but I have 2 .223 wssm and a 243 wssm and have not had any problems what so ever [img]/ubbthreads/images/graemlins/smile.gif[/img].

Thanks Guys.
I got it....Staying with the .224, as per plan.
Reed,I figure I'd save allot of time and barrel,by going with your suggestion of 7828ssc,and call it good....Would it be better to try a 1 pound bottle or go ahead and purchase an 8 pound keg and just stick with it?
Would very much appreciate some load data for your 22-243AI using 7828 with 80 grain A-Max's.
Thanks,Gary
