Thread: The race for speed

I've sort of growen out of this now but the photo still impresses me........

22-243 case full to the brim of reloader 15 and a 30 grain berger

This proved to be utter useless on rabbits but it did tear the rifling out of the barrel

That impressive

Shit thats fast.

I like it!
22-243 is somthing I like for that reason and would build one if it not for the fact I'd need to buy a barrel making business to run it

I got over 1500 rounds through an old 22-243 before it started to open up, barrels are cheap. I'm onto my 5th rifle with this chambering.......

At that speed I bet you didnt!!

no, that rifle was on its way for a new barrel a few days later...... The first one I got was pushing 55g ballistic tips at 3900fps, I got it second hand with about 800 rounds through it, it was a grunig barrel.

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

Shit nearly as quick as a Falcon aye Gav

Be careful , with running AI reamers into std chamberings already machined in the barrel , as one gunsmith said its something hes asked alot to do , but something he him self will never do , as he feels as the front of the reamer is initially unsupported/guided that the chamber does not cut true , as the edge ( at the back of the case starts cutting before pliot has any guidance or alignment ) .
He feels the chamber does not get cut straight ,

Well I finally had a chance to have a play with my new 22-243, just to prove I haven't grown up either, hope I never do !! :grin:

It is a Kimber Longmaster VT 22-250 unfired, I sent it to Robbie @ Gunworks Canterbury to put his 22-243 reamer into it, he did a Kimber Provarmint for me years ago, unfired as well.
They have a 1-14 twist like most 22-250s so only really any good for the lighter pills
The VT has a 26" barrel & is looking like it will push the 53 Vmaxs a little quicker than my old one would have.
The 53 Vmax is quite new & has a high BC, .290 according to Hornady, I will check it soonish.
It looks like I will be able to push them @ 4050-4075 ish fps, I can go faster but it is a bit hard on brass....
But this post is about speed so here it is 30 grain Bergers at silly speeds















Thats probably enough pics, good times :grin:
