gbal Posted November 6, 2013 Report Share Posted November 6, 2013 wonder why no ones made this an AI cartridge might give it a bit more fps........Tony,I'm sure it's been done-and outdone. The 20/250 is probably near the limit of this desire for ultimate achievable velocity in a 20 cal. It is extreme and 'impractical' but comes closest to the 'idea' of 'hold on fur' out to 350y.But that is coyote-fox might just be on the wee side. The 20/250 AI anyone? If you are thinking hot '6mm', you are sane,but too practical-and,damn it,someone else will have one! Gbal Link to comment Share on other sites More sharing options...
BOB LEE SWAGGER Posted November 6, 2013 Report Share Posted November 6, 2013 i did have a .204 for a short while, but bad experence as the rifle was a bag of sh*te, so like you say recoil does not come into it. i spoke to neil mckillop and said i wanted a 1:11 twist pac nor, prob go with 22" barrel, but i just needed to make sure i dont want the 17rem............20 tac seems to be my choice at the min got till thursday when he gets the action........... I have a 1in11 pac-nor on my tac 26" shoots 40vmax lovely Link to comment Share on other sites More sharing options...

The 20's ballisticly would be the superior but nobody would notice the difference in the field in real life!. Steve. Link to comment Share on other sites More sharing options...
silpig Posted November 6, 2013 Report Share Posted November 6, 2013 The 40 gn Noslers from my .20 Tac are doing 3890fps. That's from a 22" 1:10 Lothar Walther barrel. Link to comment Share on other sites More sharing options...

silpig Posted November 6, 2013 Report Share Posted November 6, 2013 Snap! N133. 25.5gns to be precise, though that is probably a bit hot. I did use it all through a pretty warm summer with no problems so will keep with it now. Link to comment Share on other sites More sharing options...

I did use it all through a pretty warm summer with no problems so will keep with it now. ive looked at his data he sent me and, he uses 25grs of n133, so that sounds consistant to me which give me hope as, ive got n133 left over from my .223 loads and i am going to use 39sbk or 40gr vmax, it will be interseting to see if any what fps a slower twist will give as mines a 1:11 and 3groove.....

BOB LEE SWAGGER Posted November 6, 2013 Report Share Posted November 6, 2013 What barrel you got on br and what ammo mate? its a cooper arms own barrel 1in 8 and I will be using 105 a max and vit 140 Link to comment Share on other sites More sharing options...

You might find it hard to get hold of those 39gn SBK's, I gave up trying to find someone who had any in the end. I did try some 40gn Vmax but I didn't like how big the boat-tail was. I found that when the bullet was seated anywhere near the lands, there wasn't (imo) enough bullet in the neck. I've been really impressed with the Noslers though.

The 204 Ruger is about 4/10at 300,but a about 28/24 by 500. History repeats!Or rather ballistics does.Once drop/drift get that much.esp drift,with inevitable wind reading erors,it becomes a very iffy shot.

Tony.H Posted November 7, 2013 Author Report Share Posted November 7, 2013 if i wanted too shoot over the 300yard mark then id of kept my fast twist .223. but i want to shoot fox and vermin so, will be happy to shoot them upto 200-250 with the 20 tac,as i am looking for a point and shoot type rifle that is fairly flat out to 250-300 yards, with lets say no recoil, so the 20tac or the 17rem fitted the bill, saying that i would be suprised if ive ever shot a fox past 200-250yards most 90% have been from 50yards to 180yards away. atb tony Link to comment Share on other sites More sharing options...

My 1-8 shoots vmax bullets into sub .25 moa and 75 amax / hpbt about .3. So the 223 is a better allround cart imo with no lack of reloading goodies unlike the 20's.
