Quoted:
I wanted Hornady's published data for RL15 because I have quite a bit on hand, it's been a great powder for my 77gr. .223 loads and my 178gr .308 loads.
I'm not dodging the RL17 or saying I'm not interested in trying the RL17 loads but from what I've read on Sniper's Hide, the guy who seems to be doing phenomenal things with the 208 gr and RL17 is using an overbore chamber to allow him to seat out to 3.00" .
I just want to see what my rifle will do with the RL15 data and if ANYONE had tried the RL15 loads.
Apparently not.
I have a bunch of RL-15 on hand, as well as a bunch of nice bullets.
I don't consider RL-15 an appropriate powder for shooting the 208 AMAX out of a 308 Win based rifle, even if your rifle has a 28" barrel.
We're trying to help you here. There's a reason why RL-15 isn't an appropriate powder for that bullet.
Because Hornady can get the 208s to exit their test barrel, doesn't mean it's the best choice for that bullet.
You seem to take the position, that because you have X amount of RL-15, you're going to make it work.
Hey, more power to you, but I and 1911 are trying to save you some money, as those bullets are probably costing you between $40-$50 for a box of 100.
Heck, we can get a fast pistol powder to work in rifles, if we spend enough time experimenting, but that's not part of the bigger picture.
Quit being obstinate and go locate some RL-17 and buy it if you must shoot your 208s out of a 308 Win rifle.
Save the RL-15 for your 150s-185gr bullets and move on.
We're only here to help. If you choose to waste your resources on some combo, it's no skin off of our backs.
