Well the question was using match bullets and my question was why not just use a game bullet with match accuracy. The cost of the sgk is the same or less than the smk, so in relation to the topic (hunting with match bullets) isn't a relivent point. If you want cheaper you would be shooting a Speer bullet as they are the cheapest I've found.
You wanted to know why people would not use SGK and I told you. That was your question...
Why would one not just use a sgk?
However, my question to you is why use a game bullet when you can use a match bullet? For example, I know this sounds crazy, but let's say there is a global pandemic. People are dying, getting sick, missing work, and companies don't always have enough employees on hand to do a particular job and then the shortages start to hit and as crazy as it sounds, not only are people having trouble finding loaded ammo, but they are having trouble finding bullets and other components...and then Deer/Elk/whatever season is upon us and people want to hunt. Strangely, one of the types of bullets that seemed to be available or on hand on people's shelves after FMJs was
match ammo.
As seen in this thread already, lots of people were already hunting with match ammo and it has done a good job for them. Why change if you have something that works and is legal where you are? If it is legal and it works well, then you can make your ethical kills. Then lots of people during the pandemic experimented out of necessity. Some where happy with the bullets they tried. Some were not. I went through the gambit of everything from FMJ, TUI, varmint rounds, match rounds, tipped versus untipped, hunting rounds of various flavors (expanding, fragmenting, controlled expansion, uncontrolled expansion, deep penetrating, segmented fragmentation) etc. etc. etc. on hogs. I documented everything on video so as to help people make decisions on what might work well for their needs or more importantly, what would not. I started such work long before the pandemic started. For hunting bullets, sometimes I found that a bullet performed as designed and sometimes I found that it didn't. When it didn't, sometimes it performed better and sometimes it performed worse. In some cases, I found that the manufacturer's design intent of hunting was not a good application for the given bullet, even though the bullet performed as advertised (TUI).
I think at last count, I have tried about 35 different bullets for the 6.5 Grendel and have seen what they will do, not in wet magazines, plywood, or ballistics gel, but in actual animal flesh. Most hunters don't have the time, opportunity, or inclination to go through all this.
So going back to your other question of why not just use a game bullet? Simple. Some of them suck, suck from your rifle, or just suck overall. Not all "hunting" bullets give the hunter the kind of performance s/he wants. Sometimes, the performance desired is what is provided by some match bullets. Sort of like hunting bulllets, not all match bullets are created equal either.
As I indicated above and will expand upon here, if you have no other insights at all and are in a store to buy ammo for a hunting, chances are that going with an unknown performance (to you) hunting bullet is likely going to be a better choice than an unknown performance match bullet, but there are lots of match bullets that hunters do really like to use and they like to use them because the work well. So why not use them if they work??? These hunters are not going to limit themselves to a given manufacturer's claimed use.
