Titegroup is perfectly fine and a very good choice in any place where a really, REALLY fast burning powder is desired. Think: small case & high pressure (9mm) or large case and low pressure (.38 Special). As I wrote earlier, it also works very well for VERY light target loads in a huge case like .44 Mag, where I run a 5.7 grain charge.
The fact that it can be doubled, tripled and quadruple charged in a large volume case is not the reason I say it is a horrible idea to use it in .44 Magnum, that is merely a side characteristic and easy visual indicator.
The fact is that when you use Titegroup in .44 Magnum at the top published loads, here is what you do:
You build a round that has the absolute MAX allowable pressure-- all the while returning the LEAST amount of velocity considering that pressure-- in a round who's pressure curve is irrationally quick, sharp and vertical.
When you use H110, you have built a round who's pressure curve climbs consistently and predictably in a manner that is specifically designed for a cartridge case of that size, to peak in a predictable and expected fashion -AND- return the top possible velocities that the round is capable of doing.
Using H110 gives you:
--top velocity, more than Titegroup could ever produce
--rational, predictable pressure curve, with no radical spikes unlike Titegroup
--powder being used precisely as it was intended, unlike Titegroup
--far, far more safe loaded round, with no pitfalls like Titegroup
--no ability, even if you dumped a case full, to blow up a Super Blackhawk
WIth the PROPER powder, you can pick a place to start...
See what happens, slowly advance the load and you can witness all the little things we look for as the pressure climbs along with the load data.
You cannot do that when you load Titegroup in to .44 Magnum!
Titegroup, for full bore top-drawer magnum loads in .44 Magnum is not only an awful choice, it may actually literally be the worst POSSIBLE choice of the popular powders widely available on the market.
