The factory hasn't been built yet but will be a joint venture between the the company in Europe making Re17 and ATK in the US
From the description, it sounds like the powder that has been loaded in short magnum factory ammo. There are very few ball powders in cannister form that share modern tech of the extruded powders.
I don't think these are high energy powders, just high density powders that are likely more temp stable.
Interesting and will be useful to those with progressive presses. There is so little tech info. Hard to know what they will really do for us.
In using the Alliant site looking at a few powders, it was funny to see Re17 listed as the slowest powder as compared to Re15 and 19. Look up the 243 WSSM 75gr HP load

Hello all,
New member here from near Helena, Montana.
I've been developing a few loads with RL17 in the 308, and 30-06. I've been achieving very good velocities without pressure signs too.
I use Quickload as an aid to load development. My top loads with 308/200s, calc 70-75K pressure on QL, but show none of the usual pressure indicators that typically show themself at around 65K pressure calc.
Interestingly, I ran some of the load data with RL17 on Alliant's website. Particularly the 300 WSM, and 300SAUM loads with the 180gr bullets. They calc in the 70-75K pressure range too, per Quickload.
I believe the properties of RL17, particularly the impregnated retardant lowering and extending the top of the pressure curve, are not clearly interpreted via quickload software formulas.
Anyway, here's the nuts and bolts of what I have been doing,
Rifle: Rem 700 VS LH, 308Win, 1/12 twist factory barrel cut to 20.5" and braked.
Brass: Win, fireformed/neck-sized
Primer: CCI 200
200 gr Accubond, moly’d
2.82" OAL (mag length, .130" jump to lands)
RL-17
48 gr - 2485 fps, very low pressure
50 gr – 2620 fps, heavily compressed, but no bullet deformation)
-------------------------------------------------------
200gr Sierra Game King BTSP
CCI 200
2.81 OAL (.140" jump)
RL-17
50 gr – 2620 fps
51 gr - 2670 fps
51.5 gr – 2700 fps
52 gr - 2720 fps (fairly heavy compression, just a hint of bolt resistance after firing, no ejector imprint or primer flattening).
----------------------------
208 AMax
3.00" OAL (touching lands)
RL-17
46 gr - 2380 fps
47 gr - 2430 fps
48 gr - 2480 fps
49 gr - 2530 fps
50 gr - 2570 fps
51 gr - 2645 fps
A few pics,
The 308, McMillan A5, Leupold MK4 3.5-10x40, and a couple test groups. These were shot at 100 yds, in a full-value 15-25 mph breeze, so there is some horizontal spread showing.
The rifle is known to handle the heavies well despite the slow twist. This 15x25" steel was shot at 1120 yards, with 208 AMax started at 2480 fps via 44.5gr RL15. Wind was at my back, 10-15 mph,
Good Shooting, Shane

I am in love with your left-handed rifle.

Hey, Shane, welcome to CGN.
It is interesting that this is exactly the same velocity as the same load you show in your Quickload printout with Re 17.
If not a typo, then this is further evidence that Re17 develops a much flatter pressure curve as the pressure is increased. If you had kept going to 51 gr with Re15, there would have been all kinds of signs of excessive pressure!
Great first post! You are going to enjoy it here.

Ted,
I pushed up to 45.0gr RL15 under the moly'd 208, and did get pressure in the form of bolt lift resistance. So I dropped back to 44.5gr, which shot well at 2480 fps, without any pressure signs.
No typo on the 48gr RL17/2480. I noted that it was the same velocity as 44.5gr RL15 too.

firemachine,
Thanks. I've got a couple more chambered in 30-06. A heavy rig, and a sporter. The three make up my boltgun battery. Keeps logistics fairly simple.
I'm thinking RL17 might be a good crossover powder for both 308 and 30-06, since I mostly shoot heavies in the 308.
The LH 30-06s,

Shane, welcome to CGN. I've followed your reports on 24hr for a while, as I have a couple short barreled .308's as well. Haven't played much with anything over 180 in them, but after this thread, I'm going to have to pick up some heavies to try...
Post the pic of your 1000yd range for the guys...(up on the hill)...

Brad,
I think this is the pic. It's a place on public land where I can set up a target down near the truck, then carry my junk up the hill. This is the 'benchrest'.....grin
Through the scope,
Here's another little shooting gallery where I can set up paper in close, or crack rocks at a distance to evaluate trajectory/consistency.

MM, great pics and love the camo jobs on those rifles. You have a few wonderful spots to shoot at. My location is very similar where you are based on a flat and shoot into a hill. I bet you find some very interesting winds coming off that hill too
Thanks for listing the QL pressures. If those values are accurate, that would be quite a high pressure load. but I understand what you are saying about a 'different' pressure curve.
I wonder if the prolonged peak pressure may actually put more strain on the action steel?

Okay, latest Norma 204 results:
180 Power Points at 2698 fps went into a tad over an inch.
220 Sierra was a disappointment, although not really unexpected. The deep seating of the bullet to fit the magazine, just takes up too much space.
Got a call from Shawn at the Sports Lodge. He has two pounds of 17 waiting there for me!

Well, we went to the range this afternoon, and burned up some Re 17 in the 308 Stevens with its 22 inch barrel. All loads were in W-W brass and used WLRM primers in anticipation of cold-weather hunting for woods bison. No wind, -14C, loads shot into less than 1 1/4 inch.
180 gr Power Points got way, way, over 2700 fps! One load was 2806 fps fifteen feet from the muzzle, however we will not be using that regularly. 2770 is plenty. Next trip will be to try 180 gr Partitions.
200 gr Speer Hot Cores got more than 2600 fps. Going to try 200 gr Grand Slams next. This may be what she ends up using if they get similar velocities.
This brass has been fired five times now. Okay, just sized them for the sixth time, and primer pockets are still tight.
Also tried some Re17 in the 9.3X62 Mauser. 270 gr Matrix bullets going 2500 fps, but that is another thread.

Now Ted, quit teasing us.
