If something gives you satisfactory results, and does not harm the rifle, then I suggest that you keep doing it. On the other hand, if you would like to see different results, you will probably need to change something. Over the years, I have found it pretty common that shooters say that they want to have better results, but when you give them a rundown on what would be required, they reject anything that their buddies are not doing, or they have not read in an article in a newsstand magazine. This would include simple things like putting out sticks with surveyors' tape tied to their tops to be able to see what the wind is doing.
Custom dies can be made for virtually any chamber including a factory one, but using them may not improve results that come from a bad barrel, nonexistent bedding job, crooked action, bad scope, or excessively heavy trigger. The trick is to have some idea as to where to start, or even if starting is called for.
I once had a factory .220 Swift that, with only a trigger adjustment, would put five premium factory rounds into a half inch or less, and handloads into about 3/8. Since that was plenty good for what I was using it for, I left it alone, and enjoyed it as it came.
I have a .243 sporter in the safe that I picked up just in case I get a chance to go deer hunting, taking shots at distances that are realistic. The first load that I put together with out prior testing grouped 3/4". I put it away because it will do everything that I bought it for as it came, no bedding and only a little trigger work.
On the other hand, my rifles that only shoot paper are another story entirely. There is no end to the experimentation, and I enjoy every bit of it.
