[QUOTE="orkan, post: 2590132, member: 25377"] Bingo. Exactly what I was describing earlier in thread. You have to give up spring rate/weight to achieve equal bolt handle lift force... and you're most often giving up ignition uniformity when you do. Primers are the limiting factor here. They need to be hit hard enough to start all of this correctly. There are tricks you can do to limit it, such as pushing some of your cocking force over to the bolt closing, rather than opening. ... but I don't like those methods as they introduce their own unique problems. ----------- [URL='https://www.instagram.com/primalrights']Follow on Instagram[/URL] [URL='https://www.youtube.com/user/primalrights']Subscribe on YouTube[/URL] [URL='https://amzn.to/3txlBnp']Amazon Affiliate[/URL] [URL='http://www.primalrights.com'][IMG]http://primalrights.com/images/signatures/sig1.jpg[/IMG][/URL] [/QUOTE]
