picked up a 1 pounder today was sitting on shelf looking lonley so i decided to help out the gun shop and the bottle....any one have any pros and cons for this powder...243 winchester, 308, 223, ? i got it for $20...figured it couldnt hurt to load a few and see... so anyone have experiance with it let me know...thanks
I did quite a bit of experimenting with RL17 a couple years ago. I found it to be the most accurate with the heavier for caliber bullets. It apparently also needs pressure to get speed. For example, speed with 70gr bullets (.243) was only so-so when compaired to a similar load with RL15 or H4350. But it was great with 105 A-Max bullets with both speed for the load and 1/4" accuracy, if I did my part.
The trouble with atheists is that they have no one to talk to when they are alone! Evolutionists and Creationists alike reject the truth.
I've used it in .280Improved with 140gr NBT and got mediocre results. I have about .75lbs left and am going to give it one more shot with 168gr SMK bullets. Of the three you listed I would try it in my .243 with 105-107gr bullets.
This is the next generation powder that is coming from Rhinemetal Nitrochemie. Supposedly the deterrent or retarder that controls the burn rate in the past was only coated on the powder granules. Now they figured out a way to mix it into or impregnate the powder. So now you get a more consistent and long burn after the initial spike. I was told the 500 series VV uses a similar process (that is why you see no 510 or 520). To take full advantage of it heavy bullets and/or a long barrel. A 150gr .308 with a 20" barrel, no big gain but a 190-200gr in a 30-06 with a 24-26" barrel it seems to shine. I've been wanting to try VV540 or RL17 behind a 190gr SMK in my 06.
The tricky stuff is best left to those who are highly experienced in operating at the ragged edge of stability and sanity.
thanks for the input fellas, I took the day and worked up 5 sets of loads (3 shots each) (some 4, I always seem to pull the #2 shot)starting at 43 grn and increasing 0.5 grn to 45grn max, on my 100 yrd range some expected thing happened and then some interesting things happened, 43 grns was way out there 2 inch group almost perfect triangle though if I do say so myself, each shot exactly 2 inches apart.... 43.5 got a little tighter but nothing real remarkable...here is the interesting part, 44 sucked in at about 1 inch group, so I figured "ok 44.5 is gonna get better or worse and maybe 1 inches is the best this stuff will do,...44.5 moved out to about 1.5 inch group, so at first I thought "ok 44 is gonna be the load for this, just not very tight or impressive (maybe that's why it had dust on the bottle when I bought it), so I figured what the h-e- double hockey sticks shoot off the 45 grn'ers call it a day, I fired off the first shot let the barrel cool, fired off the second shot, new I pulled it so I discounted it, fired off 3rd shot and it was touching first shot, so I made up 2 more 45's out of curiosity and grouped the other two touching all shots in less than .25 inches...I will post picks later but here is the info for anyone wanting...Thanks again guys, Dave
