parntz Posted December 7, 2019 Share Posted December 7, 2019 (edited) Hi, I just picked up a CZ tactical sport orange and a Accu Shadow 2. Im shooting box range ammo through them. Mostly Fiocchi and Magtech 115 gr and 124 gr. I was wondering what would be a good pound recoil spring to use in each of these guns? The TSO comes with a 16 # which I feel is on the heavy side and the Accu shadow 2 comes with an 11# which I feel is a little light. I was thinking a 13# for the tso and a 12# for the Accu shadow. Im not shooting any competitions these are just for the range. Just looking for them to be reliable and have no issues. Any help appreciated.

GeneBray Posted December 7, 2019 Share Posted December 7, 2019 Depends mostly on what round and pounder you are using. As a guide cases should fall about 6-8’ from you. After that it is what you like for the load. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

BJB Posted December 8, 2019 Share Posted December 8, 2019 1 hour ago, parntz said: ..... Any help appreciated. After you fire, notice what the front sight does. Does it dive back down past the target after reciprocation and you have to adjust back up? If so, there's too much spring. Does the sight stay up too high & you have to adjust back down? And, the spent brass is getting flung far? If so, you need more spring. Have someone video you from the side and watch the gun movement in slomo if you have trouble telling what the gun is doing. Also, as mentioned above, brass landing about 6'-8' is an effective tell too and should put you at least close to where you want to be spring wise..

Just looking for them to be reliable and have no issues. If these are range guns, why not stick with the springs that came with the guns? The primary reason for changing springs (if the gun is otherwise functioning fine) is to provide quicker follow-up shots, by limiting the dip/flip from being over/under sprung.

mveto Posted December 23, 2019 Share Posted December 23, 2019 I run a 12lbs spring in my TS and an 11lbs in my SP01. These are with anything from 124-147gr rounds. Haven’t shot any 115’s since I don’t like the recoil impulse. Link to comment Share on other sites More sharing options...
