For a hunters rifle, the vast majority of all this garbage about, "What my gun likes," is absolute hogwash.
Unless the rifle left the factory with something like the bore not being dead centre of the barrel, a poor made bore, or unless the rifle later got damaged, such as a bent barrel or damaged muzzle, there is at least a 99% chance it will shoot to hunting standards, or maybe much better, if the action and barrel are properly bedded.
The key to the whole thing is if the rifle will shoot five shots, one after the other, letting the barrel get hot, and maintain a suitable group. During the glory years of shooting and hunting, the fifteen or so years following WW2, there were a great many competition shooters and every one of us tested our rifles, to see if they would maintain POI as the barrel warmed. If they wouldn't, they immediately got bedded, because there wasn't a competition in existence, that allowed enough time to let the barrel cool between shots.
During this period I was looking for a new rifle and poured over all the ads like a kid with a Christmas catalogue. I was concentrating on what the ads said about accuracy and settled on a Sako L61 in 270 calibre. When I went to the range to check it I was almost pleading, 'please be accurate!' But no way. The groups went a good three inches in vertical spread at a hundred yards, as the barrel heated up.
Took it home and went to work on the bedding, ending with the usual pressure point under the barrel at the front of the stock and I had a deadly accurate rifle until the barrel was worn out. And there was no such thing as having to adjust the hand loads for that particular rifle. My only adjustments was to seat so the cartridges would work through the magazine and the bolt would close on the round, plus I would check charge weight, to see what I could load to, until signs of excess pressure showed up.
It was a very accurate rifle, with any good ammunition, factory or hand load, fed to it.
I don't relate one bit, to the much over used phrase, it is only the first shot that counts in hunting. I relate to the famous phrase from post WW 1 time, by Townsend Whelen, "Only accurate guns are interesting."
