120 grain hornady SST 0n a .270 Winchester

[shekarchi]

Hello gentlemen
I am a novice reloader at best.
I am trying to find some target load recipes for the 120 grain hornady SSt in .270 Winchester. I [now] know the bullet is designed for the 6.8 Rem cartridge but I bought these before I knew this and now I am stuck with them and want to at least get some trigger time out of them...
I have W760, W780, and IMR4064 to chose from...
thanks for your help!

Hodgdon lists loads for 120 grain bullets -not Hornady for IMR4064 & also for Win 760. The starting load for either powder should be safe and at least get you in the ballpark.I hope this helps.

thank you- I will not do anything unless I am sure it is safe- As I said I am new- that's why all the "elementary-sounding" questions. Here's another:
Hornady tech support said I can load it as a 130 grain bullet....
So if it were to be loaded like a 130 grain SST - what kind of velocity difference should I expect there to be?

e.g. 54.8 grains of WIN supreme 780 drives 130 grain SST’s at 2600 f/s. What would I expect velocity wise for this charge behind the 120 grain SST? consider this though- the manual says 54.6 grains of same powder would drive a 140 grain SST also at 2600f/s. It puzzles me the how lighter charge with heavier bullet gives the same velocity...
And how much would I need to cut back in order to get velocities in the 2400-2500 f/s range?
Do appreciate the advice!

Look at Hornady's customlite line. They use the 120 grain sst for their 270 win load.
Test Barrel (24") Velocity (fps) / Energy (ft-lbs)
Muzzle 100 200 300 400 500
2675/1907 2454/1605 2244/1342 2044/1113 1855/917 1678/751

Thanks- Wish I knew what powder/charge to use...
