Re: Controlled round feed vs push feed.
For long range I doubt it's necessary - or even desireable. Some may argue that contolled round feed actions are less accurate. I have no idea whether that it the case. Some will argue not having an ejector under the case head is actually an advantage...
This though is the guts of it - if it's relevant to what you intend to use the rifle for (like DG hunting) it's a consideration, if not then don't sweat it in my opinion...
This is from something I needed to put into a firearm licence application, it was based on descriptions found on the net (don't recall whose)!!
A controlled-round feed type action will feed correctly with the rifle held at any angle and even upside down. Controlled-round feed designs also prevent double feeds. This is because when the extractor has captured one cartridge, a second cannot leave the magazine without the first being ejected. Either way, only one cartridge makes it into the chamber. With a push-feed action design, incorrect operation (particularly “double stroking” the bolt) can result in two cartridges trying to enter the chamber at once, jamming the rifle with potentially catastrophic results for the hunter of dangerous game.
Full length, Mauser type extractors not only increase feeding reliability, but they take a bigger bite on the rim of the fired case, making the extraction of dirty or oversize cases, or those affected by pressure due to high ambient temperatures, more certain. Most other designs do not take as positive a grip on the case rim as a Mauser claw extractor, making failures to extract more likely.
Professional hunters and those who have a lot of experience hunting dangerous game and particularly African dangerous game in hot climates with bolt action rifles widely favour controlled-round feed designs, such as the Mauser Model 98, Ruger Model 77 and Winchester Classic Model 70.
