Jaymo Posted June 15, 2017 Report Share Posted June 15, 2017 Hello Anyone with QuickLoad who could run a few calcs for some powders as I'm trying to obtain less than 4500j and 1000m/s And 7000j and 1000m/s hme rules for a .300 WinMag Thanks in advance Quote Link to comment Share on other sites More sharing options...
dicehorn Posted June 16, 2017 Report Share Posted June 16, 2017 Before any sort of answer can be given, can you please state the exact bullet name and weight, barrel length together with the exact 300 win mag in question - there are 6 different 300 win mags - so I would assume it is the SAAMI one Quote Link to comment Share on other sites More sharing options...
Jaymo Posted June 16, 2017 Author Report Share Posted June 16, 2017 Dicehorn If your able to help that would be great. Guessing you would like my powder choices too........ Quote Link to comment Share on other sites More sharing options...
dicehorn Posted June 17, 2017 Report Share Posted June 17, 2017 If I can I will. Your powder choice would help unless you are open to suggested powders. Quote Link to comment Share on other sites More sharing options...
Jaymo Posted June 17, 2017 Author Report Share Posted June 17, 2017 Will Pm you when I'm home from work in a few days if that's ok? Quote Link to comment Share on other sites More sharing options...
Jaymo Posted July 8, 2017 Author Report Share Posted July 8, 2017 It's only me............ Was hoping to receive some help but this seems to have gone awry. So, anyone else have QuickLoad and mind running a call for me? Cheers Quote Link to comment Share on other sites More sharing options...
seeker Posted July 10, 2017 Report Share Posted July 10, 2017 (edited) http://kwk.us/ibsw.html Is there anything on this list that might work for what you need? The old Powley computer possibly? Edited July 10, 2017 by seeker Quote Link to comment Share on other sites More sharing options...
Jaymo Posted July 10, 2017 Author Report Share Posted July 10, 2017 Seeker Thank you for the link. Unfortunately not, many of those pieces of software have not been updated in a good few years. Think I'm going to have to purchase a copy of QL or just keep paying for 145gr PPU ammunition which they sell at Bisley for this very reason/purpose.

dicehorn Posted August 10, 2017 Report Share Posted August 10, 2017 (edited) Jaymo - sorry I did not get back to you - as it was nearly 3 weeks before you replied I had assumed you had found the answer to your question and therefore I binned that info + I do not visit this group often mainly because of keyboard know alls!!! So........Started again. Info provided by you: 300 Win Mag (assumed the SAAMI variety) 26" barrel shooting 178 Hornady A Max using H4350 or RS70 with criteria >4500 j 1000 m/s and 7000 j and 1000 m/s with COL at 3.340". Quickload calculations do not take into account primers so the following could have a minimal bearing of the figures. Bear in mind max pressure for this case is 64000 psi H4350 66.84 gr = 4500 j with 883 m/s giving 52710 psi Re 7000 j and 1000 m/s 71.38 gr = 5051 j 936 m/s giving 63707 psi RS70 70.5 gr = 4494 j with 883 m/s giving 45730 psi Re 7000j and 1000 m/s 78.12 gr = 5501 j 977 m/s giving 63900 psi It must be born in mind that with effect from around June next year certain American powders will be subject to new Euro laws regarding powder additives and the signs are that just about all Hodgson powder may fail therefore we will no longer be able to import them. Having said that I give below two more alternatives that would still be OK under the Euro rules. Alliant Reloder 25 73.1 gr = 4489 j with 882 m/s giving 44754 psi Re 7000 j and 1000 m/s 81.2 gr = 5533 j 979 m/s giving 63990 psi And the one I personally would put near the top of my list:- RS62 67.7 gr = 4497 j with 883 m/s giving 49180 psi Re 7000 j and 1000 m/s 73.72 gr = 5230 j 952 m/s giving 63918 psi As with all reloading please start lower than the above weights by at least a couple of grains and remember case prep is 70% towards accuracy.

Jaymo Posted August 11, 2017 Author Report Share Posted August 11, 2017 Thank you Peter very useful Will send you a PM later once I have checked out which powders we have in the 'box' Know I have some Swiss but think it's RS70, I know I have two tubs of Vectan SP7 plus Viht in two flavours too.
