The Precision Ballistics Software () breaks down the right/left wind () and head/tailwind () deflections from wind direction and speed. Without knowing what you are shooting, this may be like comparing apples to oranges but. Reckon so, but I have not entered any wind into the data.Īnd the calculations indicate the boolit will impact ~7' to the right at 200 yards-To me that's absurd. And that's what you see reflected in loading manuals.quick powders work, but the velocities are lower while hitting high pressures. Regarding quicker powders than ideal in QL - if you don't push them to extremes, they can work great in milder loads. Was this a QL theoretical run, or based on dialing in QL Burn Rates for a given powder using real chrono data? That's the only way I've found to truly dial in with QL. It's hard for me to believe that the numbers are true considering the zillions of rounds that have been shot out of 1911 style pistols using 231, HP38 and RD. Power Pistol and AA#5 are too slow and Unique is the perfect powder. Just using numbers alone it looks to me like the old standards W231 and Red Dot are too fast. That's what really got me thinking about pressure. I ran a similar scenario in the past only I varied the case volume instead of the extra powder. Unique hit the red line with 0.6gr extra. Unique had 17% less pressure but more important to me, RD hit the red line with 0.1gr of extra powder. RD burned 100% while Unique only burned 90%. Just ran a few numbers - 200gr SWC, 1.250 OAL, 45acp using Red Dot and Unique to produce 900fps. In return for the wasted powder I get significantly less pressure and way more margin of error while still maintaining the same velocity. If I use something like Power Pistol, as you said, I use more powder and waste 30% of it so it costs more and burns dirtier. Also, with Red Dot less than 0.3 grains makes the difference between safe (MAP-25%) and risky (MAP-15%). In some cases, just the variation in case dimensions between manufacturers is enough to get you over the red line.

Thousands and thousands of rounds with no issue whatsoever however QL shows that bullet seating can make a safe load dangerous real quick. Specifically for 45 acp - I use a lot of Red Dot. I've also read that the impulse from faster powders produces a more reliable slide movement and less felt recoil. I agree that going too slow will eventually leave you without the desired velocity. Lower percentages may or may not get to the desired velocity because the powder is too slow, and while the pressures will likely be lower, so too will the efficiency, accuracy, and cleanliness of the burn ('dirty ammo syndrome'). Higher percentages of 'Propellent Burnt' indicate too fast a powder and can give you dangerously high pressures to get the top velocity. Based on my experience, a calibrated load (meaning real chrono data to dial in the QL burn rate) providing a 96-98% 'Amount of Propellent Burnt' is the most efficient way to produce the desired velocity, and will produce best accuracy. Camobob - I think you're close, but my opinion is that it's more of an 'optimum' pressure versus a lowest pressure.
