At some point, I'm going to build a 22-250 or 22 cm bolt gun. But fast twist and run high BC heavies.
The gun world has come a long way in the past 15 years. Especially in case and cartridge design. Many of the cartridges just aren't particularly efficient. That's what has spurred the development and popularity of the creedmoor, prc and other families of cartridges. Is case efficiency and running proper bullet designs. Look st the 300 wm. Is does ok. Choosing a 30 cal pill at respectable numbers. But tweak the design of the case. Offer more capacity with the ability to run higher grain, higher bc bullets, at longer load lengths, and you get a much more effective round in the same action with the 300 prc or 300 norma mag.
