Who uses this powder and for what? Thanks...

45-70 and 30-30 here.

Please enlighten me as to RL5 & RL9. I didn't know Alliant produced this?

I suspect he means Accurate No5, No7, No9.

Totally different powder and would be a bad thing to use them in Reloder7 applications. As a matter of fact someone did.

I use Rl 7, in 223s, especially with 40 grain bullets....

It is my main "go to" powder in the 22.250....

It also works real well in varmint weight bullets in 243 to 30.06.... Nosler use to list it as the most accurate powder for the 125 grain Ballistic Tip in the 30.06......

I also use it in the 7 x 57 and 8 x 57... with a 170 or 175 grain bullet in the 8mm Mauser, it is an accuracy/velocity champ (working up of course)....

The bigger the case mouth and the smaller the case, Rl 7 works well in those also, like the 30/30, 32 Winchester, 32/40, 35 Rem, 300 Savage...

375 H & H, 416 Rem, 416 Rigby, 444 Marlin, 45/70, 40/65, Most of the black powder converted to smokeless powder cartridges....

Its downfall is being a fast burning powder, when slower burning powders are the most trendy...

It has excellent accuracy potential...I am never without 5 lbs or so of it in the powder cabinet...

.45-70 and RX7 go together like tires and cars.

I use it for 350 and 400 gr bullets in the 458 lott. It's a great powder where suitable.

I use Reloder-7 in my .222Rem. where it performs rather well, gives me good accuracy. I find it a rather temperamental powder though and would be careful not to exceed maximum even by a couple tenths of a grain. That's a lot in a small case like the .222Rem. I found this out the hard way, but fortunately didn't harm the rifle. I've had no further problems but watch my loads more carefully now with Reloder-7. I want to try it with my .17Rem. and .222Rem. Mag. but haven't got around to it yet. It seems to me to be very close to IMR4198 in performance.
Best wishes.

My CZ 550 458 Win Mag loves 450gr & 500gr with a dose of #7 to fuel the fire. I always thought it kind of wierd that #7 likes the great big guns and big bullets and also the litle guys too, but not too much in between.

It always seems to be a powder of choice for the .221 FB....its all I use in mine.

i use it for cast loads in 375H&H

FWIW--nosler says its the most accurate powder for shooting 125 ballistic tips in a 30-06. They recomend a max of 43.0 for a velocity of around 2900

I can use Unique to IMR4895 in the 45/70 and they work just fine. For academic perfection, I use Re7.

Seafire's use of fast powders is a challange to my process for choosing an optimum powder, but I have read so many load books, reality seems strange.

I have used it in:

218 Mashburn Bee
22 Savage Hi-Power

-Spencer

Works very well in 223Rem in AR15s, 700VS for 55gr. bullets. Powder of choice for the 45-70, from what I heard. Jay

218 Bee and 45-70.

I use it for my 375WIN, the only round I use it in.

I use it with cast bullets in Hornet and .243, very accurate in my guns.

Reloader 7 is also THE powder to use for the 7.62x39; especially when using the 123 gr. bullet.

I know it is almost as cheap to buy factory, but I just cannot resist reloading for it anyway. I must be sick.
