Good Grief! Use the 130 grain data.~MuirHi chaps just wondering if anyone out there is running this combination? i can find data for 130gr heads and RL17 not the 129sst. Hopefully someone here can help me out cheers.
Precise? Really? Have you weighed those SST's to make sure they are 129 grains? A random sampling of 15 of my 140 grain 6.5 SSTs gave weights from 138.4 to 139.8 grains with the majority weighing in at 139 grains. You might want to weigh them before you start talking precision. SST's really aren't a top end precision bullet. (I shoot a lot of them)There is a very wide range and i like to be precise.
Just a hillbilly with too many guns and internet access.1gr difference,read what muir wrote as he invented reloading and is sd guru, ive only ever weighed a couple of bullets just out of interest, if I had some good digital scales I might batch them
You're not far off.Hi Muir.
Since you were described as The Hillbilly with too many Guns and Internet access I have always had the Jed Clampett image in my Head .
Caution is good. Carried to an extreme, or letting it overshadow good common sense, can turn it into a real stumbling block. It is a common ailment of the new reloader to believe that everything is in absolutes: A 129 grain bullet weighs 129 grains, velocity listed is what you can expect, any load under maximum is safe... All not necessarily true. As you have noted, the heavier charge listed for the 129 is the same charge as the 120. In this instance it makes sense: less bullet weight should be safer -or as safe- with regard to pressures. ~MuirMuir im a cautious reloader certainly way of being an expert. Currently running the 120amax and RL17 and was only seeing what I may have to drop back by although the hornady manual says use the same for a 120 as the 129sst
