guys i need some good info about this caliber i have a 6mm rem. sporter that shoots decent and would like to chamber for this wildcat. should i shoot the sporter out , or go ahead and get a barrel and have it chambered .is it worth the extra money to have it done just bought a 6mm varmint that i was going to put on becuase i like the varmint fill. will be shooting coyote and deer would like to keep it in the 1-10 twist . also will it be hard to use it as a repeter. all and any info will be accepted.

I think you know you don't need a new barrel, just ream the one you have to 6mm AI. As far as using it as a repeater, alot depends on the action.
Is it a remington. A push feed short action in 6mm AI could give you some feeding trouble , but a good smith should be able to get it to work.
Using different bullets and playing around with seating depth I would bet you would find a good combo that would at least feed the 1st 2

I have not had any real feeding issues with the 244 AI( 6mm Improved) in the 700 short action. I seemms to feed better than the 243AI.
I am not a fan of rechambering factory barrels.

To do it correctly you need to set the barrel back and rechamber.

All AI cartridges should have a slight crush fit to properly set headspace. You should feel a little resistance when chambering a round the last 1/3 of bolt travel.

I picked up my finished 6mm AI rebarrel on Monday and took it to the range for the first time today. The rifle is an old Remington 700 6mm Rem that I bought 40 years ago. I still want a light weight sporter, so I picked a take off .243 24" sporter barrel. I hope this works out, if not I will be buyimg a new SS barrel.

I was just fireforming cases today using max 100 gr. 6mm Rem reloads @ 25 yards. I chronographed some and was getting 70 fps higher than in the old 6mm Rem!! Strange, but I guess adding 2" to barrel length means a lot for this cartridge.

If you are comparing 2 different barrels I've had 2 barrels the same length show that much difference.
