How new are you to using a bolt action (roughly how many hours have you gamed one?)
Any name brand bolt action can be good, it just needs proper upgrades, and to be properly upgraded.
Spring is much more consistent than gas, you can produce more accurate results with a spring rifle than a gas rifle.
Using a bolt action is 90% movement, 10% your gun... don't expect to be standing at the back of the field shooting people's hands as they come out from cover.
