Slug Loads with RL-17 powder

[leadhead 500]

Been trying out some 12 gauge slug loads with RL-17 powder and want to know everyone's experience has been with that power and slugs. I tried some rl-17 in 3 inch hulls, bp gas seal, bp flex seal, shot cup, and Federal 209A primer with a strong roll crimp also tried using a fold crimp. Shows no signs of pressure but there is unburned powder in the barrel after the shot. I also have a Lyman .735 round ball mold and wanting to get a accurate full bore slug mold to try with the RL-17 powder

Slower burning shot shell powders would probably be a better choice. For higher velocity slug loads I have been using ProReach, Longshot, Steel. For the round balls I am using medium burning powders.

I have loaded a bunch with blue dot and steel. Check out the super blazing sabot thread on using the RL-17

[Hogtamer]

Hey Leadhead, don't know about that powder but always interested in what you're up to! The search is on here for a good full bore slug that weighs less than my Toyota! Longbow and Jmort are on the hunt too.

[leadhead 500]

I have read a bunch of the fullbore threads and lots of good info. Good to hear from you Hogtamer

You aren't using enough powder.. what weight slug in

the wadcup. does wadcup have its own seal.

Anything under 525gr you want all the RE 17 you

can get it un der a seal. THere is danger of squib loads

with too little powder. Ed

^^^ This is from the man who would know.

The load I tried is a

Remington 3 inch nitro hull
Fed 209A
100 grains RL-17
Ballistic products gas seal seated to 90# wad pressure
Ballistic products flex seal
Winchester AA12 shotcup cut off from was
Lyman 525 with base glue filled with hot glue

There is unburned powder in both of my guns H&R ultra slug hunter and a Savage 210
Tried a fold crimp and a heavy roll crimp

[hubel458]

I only cut Re17 loads back to 100gr powder when using bullets over twice
that heavy. If using BPI powder seal leave
out the flex seal and fill extra room with powder
and thin cushion wads if needed .
Should get in max of 130gr in 3" case, if learning start at 115gr,
it'll be ok, and go up 5gr at a time. and you'll get the speed, we all
found is possible. Use roll crimp.

But load might work with AA12 one piece shotcup with its
original seal. Check other threads here about using the Lyman
and see what combos of seal, wadcups, etc they use.

Also make roll crimp is down on the top outside edge of the slug
so that the slug opens it on firing. Crimp can be down over the
top edge of wadcup, but it must be down on the slug.Ed

Why Pay for and Burn 100Gr of powder when 35-45 would do? It's simply a waste of Money, and additional recoil. The 525 Grain Slug does not require super slow Powder to work. Slow Powders in the 12 ga are needed when you exceed 800-1000Grains in weight. You'll save alot of money and Time using a more suitable powder, 4756, Longshot, Blue Dot, etc. I would even think Alliant Steel would be too slow, and have excessive muzzle Flash in your Application.

I think this powder is far too slow. Those unburnt grains are there because it isn't getting up to the pressure and temperature which will make it burn fast. In theory you can compensate by using more of it, and the only disadvantage could be the expense. But it is unlikely that the proportion of burnt and unburnt grains is going to be constant.

That could be a sweet load what would the FPS be for that and could one use 7/8 oz slug with that load must be close to 2000fps?

[megasupermagnum]

Bluedot is great powder, especially for the slug weight you are talking. I'm actually looking into trying RE17 myself, as my 770 grain slugs are about topped out at 1150 fps with Bluedot, and gives sticky extraction past that. 100+ grains of powder is a real heap, but if I were trying to conserve, I wouldn't be sending nearly 1/8 of a pound of lead downrange every shot.

[pashiner]

I somehow doubt that 7/8 oz slug would provide enough pressure for re17 to burn. Of course, I haven't tried it myself, so ymmv.
