What I would love to see are Berger trial packs where you could buy 20 bullets so you could try out 4 or 5 bullet weights to see how your gun likes them before you jump into buying a full box. I know that would have helped me when I was trying to find the bullet my gun would shoot best.
I've thought a few times a sampler would be good. Then I realized it would have to have at least 50 of each bullet to give them a fair chance, especially varmint bullets because my varmint rifles need to be more accurate than my deer rifles - I shoot tiny ground hogs at longer distances than I shoot the relatively much larger deer. That's a lot of bullets, and once one works "good enough", a lot of extra bullets, especially for flat shooting varmint rifles because barrel life is frequently the most expensive per shot cost compnent. I tend to buy a rifle to shoot a particular bullet weight and type at specific game. I stop experimenting when I get the first bullet to work.
I don't need a lot of bullets for my deer rifles. So when I buy bullets for my deer rifles, I buy a box of 100 and know that is a several year supply including load development. I seldom need more than 40 rounds to have a useful (1 MOA or less cold bore 3 shot groups) PA deer load for a bullet in either my 7mmMAG or .30-06. I seldom go through more than 9 rounds in a hunting season. 2 fouling shots, 3 cold bore cold zero shots at the range to verify the scope and get reacquainted with the rifle, 4 shots at deer if I am lucky, less if I'm not. My scopes appear to hold their zero for years, so I don't use ammo adjusting them.
When I buy bullets for my varmint rifles on the other hand, I tend to buy at least 200 bullets knowing that is probably a 3 year supply including load development. I shoot 30 to 40 ground hogs in a typical year plus 3 fouling shots before the first hunting trip and 3 more following a typical mid season bore cleaning. If I buy varmint bullets locally I tend to buy less at a time than if I buy online for shipping/handling cost reasons. If I was a PD hunter I'd probably buy bullets in boxes of 500 or more. As it is, 200 or 250 count boxes work just fine.
When I find a good accurate bullet/load for a particular rifle and the game I hunt with it, I usually stop experimenting and just buy more of the same components.
Sometimes I have a hard time finding a bullet that works well in a rifle. My .17 Remington being a case in point. It doesn't like the V-Max bullets so I'm going to try the 25g Berger varmint bullet in that one next month.
Finally, on infrequent occasions I luck into another bullet that works significantly better with the same load than the one I developed it for. 34g DogTown working much better in my CZ Hornet (accuracy and terminal performance) than the 35g V-Max being one serendipitous example. A friend was going to pitch the bullets and gave them to me instead. I was barely satisfied with the 35g V-max in the Hornet, so tried the 34g DT, loved the accuracy and terminal performance, and immediately bought 200 more. Had a dozen or so one shot kills with them this spring out to 160 yards on young GH just venturing out of the nest.
