F class is shot by single loading the rifle. No mag is required or allowed. You DO NOT need a solid bottom action. I use a mag fed action with a Hi Score BR follower glued into the bottom.
The rig is very competitive even if the driver is not
F class is so much fun and the most likely sport to be found for LR comp these days. Quite a few ranges now offer it at distances from 300m to 900yds. You just have to check around to see what is available in each province. Check out the LR comp forum here and you will see events listed and contact people to help you out.
F class is also the least expensive type of competitive shooting. Many clubs are making the effort to put in a factory class so more shooters can come play without spending huge bucks.
You want to contact Obtunded and ask about what the rules and goals are. He has really done a great job of moving this class along in western events.
For the distances you want to shoot, the 223 in a 9, 8 or 7 twist will be a wonderful starting place AND there are classes already set up. Helps to keep the equipment race to a min.
A Savage HB in 223 would be my recommendation for a starter rig. The 12BVSS is likely the ideal rig and was around $750 (not sure what they are going for these days). You can put on a workable scope for around $400 to 600. Base and rings for another $150.
It will be very hard to hit sub $1000 on the line but you can get there without too much expenditure. You will also need to budget for a bipod but a Harris with pod lock works just fine.
Bed the action properly and work up some loads using 75 or 80gr Amax or bergers and you have a competitive rig in F T/R or factory. If you can find a 7 twist Savage, you can load up the 90gr Bergers and have very good LR ballistics.
Ballistically, the 90gr Berger VLD may make the 223 BETTER then the 308 at all distances out to 1200yds. This development is happening very rapidly as newer powders are released for this case.
There is lots of info on this board and many of the best competitors in this sport post here often.
You will get your questions answered but the most important thing....
COME OUT AND PLAY
