The N140 load was set at a lower velocity performance level because I was uncertain of its temperature sensitivity at higher temperatures, and I didn't want to reach over pressure levels. The IMR 4166 load used was the same grain weight value as the IMR 4064 load since the two powders have been reported to have comparable performance. The IMR 4064 load was calculated using QuickLoad V.3.9 (2015 database) to achieve similar velocity using a Berger 200 gr hybrid bullet for the bullet value and default temperature setting of 70 F. 308 Winchester bolt action rifle with 30 inch Bartlein 5R 1:10 barrel Lapua Palma brass (4X reloaded following neck resizing at 0.002 tension) CCI BR4 primer Berger 200.20X Hybrid bullets loaded at 3.02 inches COAL (0.02' off lands)Ī Varget load for the cartridge that gave 0.39 MOA accuracy performance at 200 yards (2583 FPS at 71 degrees Fahrenheit) was selected.

Data from the first test would be used to conduct a more detailed second test with promising powders. The initial tests only used 3 replicates shots per powder per temperature. The first test was a wide-range survey of 4 powder temperature-velocity responses. The temperatures I used in the tests cover the range that I experience in F-TR rifle matches in North Central Florida (34☏ to 102☏). The purpose of the studies was to identify a powder or powders that may have temperature insensitivity comparable to that of Varget. This website reports results of temperature-velocity tests that I ran with Varget and 3 other rifle powders reported to perform well by competitive F-TR shooters. Unfortunately, this popularity and high demand coupled with limited importation of powder produced in Australia and marketed as Varget in the United States has resulted in recurring shortages to U.S.
Varget's positive reputation for being relatively insensitive to temperature-dependent velocity changes puts it in great demand. Like many other F-TR shooters, I have been using Varget powder for bullets in the 175 to 208 grain range. Tests for a Possible Varget Powder Replacement in a.
#Quickload 3.9 update
So you say you got the Enduron Powders in the 3.9 updates, my update they sent me is dated Jan 2016 and has no Enduron Powders. I don't know ? am I missing something ? thanks for any help. when I set up for 375 dia and go to 300 gr I go from Colorado bonded bullet to FMJ RN. the other day we were talking about a 375 ruger using a 300 gr cutting edge bullet. I still can't find cutting edge bullets by doing a bullet dia search. QuickLOAD has a default database of predefined bullets, cartridges and propellants. Note that there are, if I remember correctly, 1200 bullets, too many to list here. As related to another post - QuickLoad Powders - here is a listing of the bullet companies represented in the latest QuickLoad update for '3.6 through early 3.9.' I don't know if there are more in the whole new program of 3.9, which costs the big bucks.
#Quickload 3.9 software
Will run on MAC with Windows emulation software 3.9 is win 10 compliant You can now import information from the QuickDESIGN program into for QuickLOAD for ballistic analysis-exterior and interior! Schematic and/or photos of most cartridges in library are available at the click of a button. Version 3.9 requires Windows XP or newer OS. A brief explanation of how I choose a powder using the QuickLOAD reloading programme.
