Ronan Posted May 24, 2015 Report Share Posted May 24, 2015 Lads, I have an AI AT in 22/250 with pm11 5-25-56, interested in starting f class Was thinking of a 30" fluted 308 barrel & f class bipod ( possible problem with weight ??) Really like the AI and scope combo Would it be worth my while staying with the rifle or say going with a dolphin dedicated f class rifle. I also like the option of going back to the 22/250 for long range varminting which makes the AI ideal. Would the AI with the right barrel,scope,bipod be competitive Link to comment Share on other sites More sharing options...
The Gun Pimp Posted May 25, 2015 Report Share Posted May 25, 2015 Competitive yes - but would it make FTR weight with the S&B scope? Unlikely. But, you have an Open Class rifle already - which would be OK out to 600 yards - why not try a few F Class shoots to see if you like it before spending any more money.

Can you shoot a 22/250 in f class. If I went down the road of f class what scope & bipod, barrel would make the weight with the AI Link to comment Share on other sites More sharing options...
The Gun Pimp Posted May 26, 2015 Report Share Posted May 26, 2015 Funnily enough, Bill Wylde (best known for his 223 Wylde chamber reamer fame) won the first ever National F Class comp. in Canada with a 22-250. You would be shooting in Open Class and the all-up weight is 10kg (22lbs) so, even with a decent bi-pod attached, you'd be in weight easily with the AI. Try a few shoots - see if you like it. What area are you in? Link to comment Share on other sites More sharing options...
Laurie Posted May 26, 2015 Report Share Posted May 26, 2015 If you have access to a private range, you have no problems with 22-250. If it's Bisley or an MoD owned facility, JSP whatever they are range certification rules prohibit anything with an MV exceeding 1,000 m/s (3,280 fps), that is the old 5.56mm M193 load with the 55gn FMJBT. This applies irrespective of bullet weight or muzzle energy. If your 22-250 has the standard 1 in 14" twist rate, you'd be limited to 52/53gn match bullets and have to download the cartrtidge a huge amount, so much that this raises some potential safety issues. For this reason, the Sporting Rifle people who shoot the Running Deer at Bisley don't allow the .22-250 even with match / FMJ bullets and with claimed downloaded MVs.

Laurie, It's a 1 in 9 twist good with the 69grn smks might try some 75grn a max. At some stage I will go for a 308 just unsure which road to go down with the setup I have Link to comment Share on other sites More sharing options...
