Greetings @Micky Duck,
And use that load is exactly what will happen. It is just my nature that when I see an anomaly I just have to dig into it to see what is going on with the load data that is so different to what I am getting. This is magnified by the shite weather we have been getting in HB lately. @Bos has kindly supplied some data in the previous post which will enable me to draw some conclusions in a separate post.
Greetings @Bos,
Thank you very much for that. Using the same AR2213SC powder, I assume, and the 129grain Nosler LRAB we are both getting almost exactly the same velocity. The difference is that I need an additional 3.5grains of powder to get it. I spent part of the morning going through old load data from old Handloader mags and loaddata.com and all of the data from the 1970's and 80's agrees closely to the rifle I am loading. Your rifle is more in line with current data. There must have been some changes to the barrels which would account for this. Some of the loads listed in the old data would take a modern one apart.
Thanks again Grandpamac.
No problem - happy to help
I was using 52 gr Reloder 22 but when Id used all that up, was forced to develop a load with the 2213SC. Not a big deal but 49 gr didn't group that well, nor did 50gr so I settled in the middle only to find that Id set the scales to 49.6, not 49.5.
That thing of mine has a carbon wrapped 22 inch barrel (1:8) so just how much difference that makes is any ones guess
nope...WRONG
BECAUSE all good reloaders will have followed the directions printed in every loading manual (yeah right TUI anyone) and reduced by 10% and slowly worked back up....
and that my friends is the difference between then and now...back then,30 or so years ago,people actually worked up a load or just stayed low..now its I WANT IT NOW NOW NOW NOW,,gimmi gimmi gimmi the exact data to use and I will go slay dragons at a mile with no practise....
manuals also used to have load data for weight group of projectile NOT a specific projectile.... people have got lazy and manufactures have got lawyer shy.
75/15/10 black powder matters
Bit late to the party but I get good results with n560 in the 130-140 range, have some 147s to have a play with pne rainy day
