As rabbitslayer illustrated, most of the reloading manuals lump all of their certain-weight bullets for a given caliber into the same powder start/max recommendations, regardless of flat-base, boattail, ogive, etc. While jacket thickness and amount of jacket contact with the bore are probably the two things that affect pressure variations the most, if I use a certain weight bullet as shown in the manuals that is of different manufacture, start at the BOTTOM of the recommended powder settings, I feel pretty safe in having worked up scores of such loads over the past 50+ years and have had no bad incidents over-pressure when starting out. Keep in mind this only applies to when using copper-jacketed, lead-core bullets. If using solid copper bullets, steel core or such other types of bullets, additional care and scrutiny should be applied - as well as ascertaining the load data in the manual isn't rifle-specific - such as for a bolt gun if you are using a semi-auto, etc.,
If you are just plinking, and not concerned with extreme accuracy, the "bulk" bullets can be fantastic deals as compared to the "premium" bullets. Interestingly, the bulk FMJ military-style of bullets that are so often sold in bulk actually often cost more than certain name-brand varmint bullets (like V-Max and Nosler Varmageddon, etc.) and USUALLY don't shoot NEARLY as well. I have bought bulk varmint bullets that cost as low as about $9.00/100 (look at those "Varmint Nightmare" bullets from Midsouth Shooters Supply, as an example). They shoot about 1/2" MOA in my rifles. While I have other loads with other bullets that do a lot better - sometimes I don't need better. Really cuts down the cost of shooting in these days of high prices for components. Shooting "seconds" can provide a lot of savings, though the quality of the seconds varies a LOT depending on where you buy them. Go to Midway, USA and click "Clearance" and hit tab "over 50% off". Midsouth Shooters Supply also usually has a selection, as does Shooters Pro Shop (all Nosler products). From my experiences, Shooters Pro Shop quality is the best of the "seconds", though their prices have really come up in recent times.
