My .22/250 ackley has accounted for an awful lot of foxes, and with the amount of shots i've put through it (1,000+ in last 12 months, I like playing!) I think its time for something else.

I've shot the RPA's and think that will be the make to get, but cant decide what calibre, as a pure fox/light vermin round. I all ready have a .243ack, 7mmRemMag and a 17hmr. I've got a nightforce and a PES mod ready.

What do you chaps have thats got a flat trajectory, and good for the red ones out to 400yds. i'm tempted by another .243ack, but set up for light VLD bullets. I'm not sure if my FLO will let me have two though. Guidance please!

I'm using a slow twist 6-284 with 71g berger bullets for fox and coyotes - the 71g bergers do very little pelt damage. What are you shooting out of your 243ai?

Hi, i like the 6-284 also,but another nice round is the 22-243 middlestead if you want really flat trajectory.You could either go with something like 55 grain ballistic tips or 75 grain a-max.

SWS ,
By light VLD bullets I assume you probably mean the 95 gn Berger . Bear in mind that this projectile doesn't seem to shoot well at over 3150 FPS . My .243 AI (9 inch twist) is capable of 3300 with this pill but accuracy is poor .
Have you thought about a 6BR Norma ? Probably a single shot proposition only . Do a Google search on it and you'll find a forum with all the info. you need .
Reckon a .204 has got to be close to the perfect fox rifle if you don't collect pelts and want reasonable barrel life .

sws whst about 6mmbr ?

If you want something a little different to a standard 6br how about a 6 dasher? Also another nice round with more go in it and less hassle than the dasher due to no forming is the 6x47 swiss match,the brass quality from RUAG is excellent.The new 6.5x47 lapua would also make a nice efficient and highley effective round if necked down to either .22 or 6mm

SWS,

I also have a 22-250AI, it has done about 1300 rounds and is showing very little throat erosion (5 thou extra oal) I use almost exclusively 75g A -max for foxes, and 63g Speer for roe in scotland. If you want another fox rifle then why dont you just have the barrel set back with the AI reamer? - you already own what I consider to be the best chamberings for fox anyway. If your barrel has a slow enough twist (1 in 8), try the A maxes, they are very, very good out to the distances you mention. If you want to go a bit more extreme, why not get a 22-250 AI with a 1-7twist and try the new 90grain Sierra SMK or the 105g Wildcat ULD RBBT?

Thanks for all your advice.

I do quite fancy an RPA, and will have a chat to them about Andy Mass's sugestion of the 75g a maxs.

I'll let you know how the project goes
