While the terms Reloading and Hand Loading are often interchanged, they really is a difference in the two. It’s the sort of thing that only matters to those it matters two, and then, those people are likely to be hand loading.
At some point, you have probably heard the term Ballistic Coefficient. People on ranges love to compare and argue about what bullet has a better BC. But what does it actually mean?
People reload their own cartridges for a variety of reasons. For some it is financial, some it is because you can’t source the ammunition any other way and for some because they want to maximise the performance of their firearm.
A grain, as a unit of measurement is equal to 64.79891 milligrams, or 0.06479891 grams. 16 grains is just under 1 gram. The unit originally comes the Bronze Age – where a grain of wheat or barley was considered a legal definition of mass.
I was talking to someone on the weekend regarding sizing and different calibers. Trying to explain caliber sizing to someone who knows little about firearms can be a bit of a challenge – mainly because it really isn’t a standard convention anymore. I thought I would put together a short article on how, why and the differences in naming calibers.
The Annealing Made Perfect machine is a new(ish) New Zealand made unit that bridges the gap between home annealing and factory/lab systems.
Five factors that affect your reloading scales accuracy
Are you potentially chasing your own tail when it comes to neck concentricity?
I am always keen to develop and test new methods of load development. Anything I can do to speed up the process of finding optimal loads – it means less component use and more time to practise my shooting and confirm ballistics and less testing loads.
The new generation of VLD (very low drag) projectiles have brought with them more accuracy, and more requirements to optimise. It won’t be new to shooters that bullets have a sweet spot when it comes to seating depth. For a long time F-Class and BR shooters have been ‘jamming the lands’ – setting seating depth out long enough where the bearing surface is actually touching (or even slightly pushed into) the throat of the rifling. Minimising jump eeks out the final bit of performance.
