Thread: The race for speed

Have you tried any heavier pills in your 22-243? I'm using 80 targex's @ just under 3500fps in mine but haven't tried anything lighter yet.

I've have vairous twist rates over the years, 1:12, 1:14, 1:8, 1:7 and back to 1:14 now. I only use it to shoot rabbits to 400 meters max and have only used 55g Ballistic tips. Except for the 1:7 twist that now kiwi greg owns which I build to shoot 90g bergers at about 3200fps I've had no need to change.

I got a few FPS faster with my slow twist 22-243, 30 bergers & 2207 but was blowing primers, got them cruising at 5000 but never shot any thing with them.
I have the 1-7 mentioned above, it is bloody awsome, 90s at 3100, I can get 3400 but they don't get to where they are supposed to far too other
It is very consistant & will normally hit the steel 1st shot out to 1100.
The best I have done with it is bunnies at 900 yards, got one the other week 1st shot at 646
I'm tempted to get another Kimber 22-250 & get Robbie to rechamber it for the liitle pills real fast, I might grow up one day.........Nah probably a Tui add

Nah too slow, get it reamed to 22-243.

The problem with 22-250 as a donor rifle is they are 1-14 so only little pills will work well.

It will be back from Robbies tomorrow, in time for some testing in the weekend if I'm not busy......probably will be.....bugger...will have to make time
