Against my better judgement I have ended up with a quantity of .243 WIN home-loads from a well-meaning friend, who insisted they would be so much more accurate than factory amo. Trying them out they do not group any better or worse than my preferred factory Federal Power-Shok 100Gr SP amo. And that doesn't surprise me as you can see, with the naked eye, and without using any measuring tools, that the bullet seating varies by some 2-3 mm, resulting in it being impossible to use some of those bullets, as the bolt cannot be fully closed on them. Hmm. The neck of the cases has been trimmed so irregular that the cases are also clearly of a different lengths, again with variations of some 1-2 mm.
Another also well-meaning friend, has also 'insisted' I learn home-loading and gave me a crash-course one afternoon. Once again the resulting amo was anything but of regular appearance.
Both explained to me the importance of measuring the neck-space (whatever that is...) which apparently comes down to hundreds of an Inch, only measurable with a specialist tool.
I find it quite impossible to reconcile that essential accuracy they deem necessary with the actual results of the amo they both produce. And I fear the worse if I would have the amount of Grains of powder checked.
So having drawn my own conclusions I will stick to factory amo...
