162s will be the common pill around here id suggest starting at 70gns with 215 primers
Cheers Kelton. Already running 162gr eldm. Just looking at trying the sierra too. Awesome thanks mate .
#1 pick up reloading manual #2turn to 7mm magnum page #3 find data for 150grn projectiles #4 scroll down till find powder you actually have on hand#5 select load 10%below maximum and try it#6 if all is good try slightly more powder in next batch#8 be happy with accurate load. Or just pick load in middle of range of your rifle is NORMALLY happy there,load some loads and also be happy
I deliberately left out #7 so the anully retentive can tell you all about seating depth variations.i personally set up die using existing accurate load and call it good
Cheers Micky.
basically bud...its a cup n core pill so any data from older manuals will be relevant..its only in last 5-10 years that data has been projectile specific.....because people got lazy and manual makers got lawyer shy.... Ive got 4-5 manuals here if your stuck,tell me what powder you actually have and we can go from there,no use giving you best most accurate load with unicorn tears powder you cant find LOL.
Any reason why your looking to switch from the eldm?
Thanks Micky. I have 2217 and have found a load for h1000 which is the same so I can start there I guess.
@keengunNic not looking to swap as such but just thought I'd see how they go. Bloody good question though ha ha
ASSUME NOTHING.... I shall have a look and see if have something on paper.Quote:

that data is from ADI MANUAL early 2000s do you spot the irregularity/possible error in the 2217 data?????
thats why I always look at all charge weights n compare and dont just read one line or trust internet given data.
Thanks Micky I appreciate your help mate.
have you seen the error yet????
Is it the lower velocity?
nope.....162grn data is "out of line" with the rest 130-140-150-160 are all + ten grains bullet = -2grns powder YET the 162 powder is heavier than 160.....
if you look at the other powders in same way you will also see the pattern repeated the 2213 is the same..and again when gets to 162 it goes haywire.
spotting these things can save your arse.......if anything the 162grn powder charge should be fly shit lighter than the 160grn charge.
And this is why it is not a good idea to use data that does not specify the actual projectile used. Two years later Hodgdons repeats the same data for H1000 (same powder with a new name) and shows it to be a 162 grain Hornady SPBT a soft projectile.Quote:

A check of the Hodgdons on line data shows the same 160 grain data for H1000 (AR2217) and the 160 grain Nosler partition so there we have it. Both sets of data are relevant when you know the whole story. The same data, including the actual projectiles likely appears in the current on line ADI data, Always best to use the latest data possible.
Hodgdons also identifies their data for the 150 grain (again the same data as the old ADI handbook) as for the 150 grain Nosler Partition. This should be fine with the softer Sierra but once again work up from their start load. Surprisingly they list hotter data for the Barnes 150 grain TTSX, a much harder projectile. Now there is something to be concerned about Micky.

Thanks guys. That's why I thought I'd post it on here as I couldn't find load data for the gamechanger online.
Gpm. With all due respect... The actual projectile won't matter a fuck IF you have dropped by 10% and are working back up. The 162 data shown above is an abnormally and I wouldn't load to that level at all. To do so would be foolish when you look at bigger picture. The type of projectile is a moot point if the powder charge is that far "off the line"
Ttsx has more bands around shank to LOWER surface area of bearing surface and as I put above SOME of the game changers are harder than normal and giving high pressure..... Proceed with caution,as always
