seeker Posted July 31, 2016 Report Share Posted July 31, 2016 If its one off the major manufacturers it should be on the spec sheets on their web sites ...

Savhmr Posted July 31, 2016 Report Share Posted July 31, 2016 CZ 527 twist rates varied between older and newer models. I think the later ones were a 1:9 twist. You can check yourself by marking a cleaning rod with tape wound around it with a 12 inch interval. Put a nylon brush or dry patch and jag onto the end, and pass t through the barrel. If you put an ink mark on the rear tape, just count the number of revolutions as the rod passes through 12 inches. Quote Link to comment Share on other sites More sharing options...
bullet1747 Posted July 31, 2016 Author Report Share Posted July 31, 2016 Well I've had a bash the barrel is 600 mm I recon it's a 1.12 twist does this sound about right and is this ok for the heavier grained bullet Quote Link to comment Share on other sites More sharing options...
Walker570 Posted July 31, 2016 Report Share Posted July 31, 2016 You really will not know until you try it. Barrels are female, they like some things and dislike others but with no reasoning. Get up to 1-14 and you may struggle to stabilize the heavier ones but I would lay odds the barrel will shoot them OK. By the way I have shot that model rifle and itwas a tack driver, great calibre as well and will still do the job. What are you looking at 60gr, if so the V Max is a good bullet and I have shot a lot of roe with the 60gr Nosler Partition if you can still get them in the UK.
