I havent done any Cast bullet loads yet.I am using Starline cases,WLR primers,400 Gr Speer softpoints and 22 Grs/ of N110.I have`nt Chronod it yet,but am hitting a 12" Steel plate at 100 yds. consistantly.I started at 16 grs and worked up.Right now its all I can handle.Suckers a handfull,but not pain full yet.I put about 100 Rds down the Tube and must say the revolver is more than I thought it would be ,quality wise.I cant wait to start shooting cast bullets.Should group pretty good with that cut rifled barrel. Later OB

That's great, OLBIKER!! I'm glad to hear that you like it. It's a great piece! Once you start pushin those 400+ grain bullets up and over 1300 fps, they will certainly get your attention from a recoil standpoint!

I know what you mean about being a handful, my BFR in 500 Mag is that. Now my 45-70 BFR is not bad at all.

I have shot bfrshooter's .45/70 BFR quite a bit and I agree that it's not bad at all. It's actually quite comfortable to shoot!

The only thing that bothers me is your starting load of 16 gr's of H110. That is too much of a reduction for that powder. I would not use less then 21 gr's for a reduced load.
My most accurate load with 296 and the 400 gr XTP is 25.5 gr's.
If you want a pleasant load, use 15 gr's of HS-6.
Do NOT fool with H110 or 296 at those low levels.

That is some great advice, H 110 and W 296 with reduced loads can produce some high pressure's and blow up your gun. If you read warnings on H 110 and W 296 you may want to reconsider your powder charge.

Low powder charges of H 110 or W 296 will actually explode in the case instead of burn.

Good catch, I did not look at the powder he was using and the low charge he started with. N 110 is about like H 110 or W 296.

You are right.I was using (N110)not H110.15.3grs is the starting load.I got about 8lbs of this stuff and like it a lot.I should be getting 1250FPS from 22 grs. 22.5 grs is MAX for about 1300FPS. later,OB

OLBIKER -- do you have a chronograph?

OK, good. I never used N110 so I checked the burn rate chart and it is faster, almost 2400 speed. Should work fine.

Be careful with the Linebaugh load of 29 gr's of 296 with a 440 gr boolit.
I have a 429 gr WLNGC boolit from my home made mold that sticks brass with 26.5 gr's. It is extremely accurate with some 5 shot groups at 1/2" at 50 yd's but I had to drop to 25.5 and 26 gr's. 26 still gives me 1348.3 fps. That did open groups a little.

You have focused on a problem I'm having with .475 loads, and to a lesser extent with .480 Rugers. Where do new shooters of .475s find pressure tested loading information -- online, or printed manuals?

Hodgdon's has substantial data on .480 Ruger, so the need here is no longer pressing. But their .475 data is sparse.

Not having a clue what I'm doing with .475s, I'm reluctant to use anecdotal reloading information first. Better to baseline on known data.

Yes, it is a common problem with the .475 and also the 45-70 revolver that can't use slow rifle powders.
I found some info here, www.chuckhawks.com/475linebaugh.
If you google .475 Linebaugh there is some more.
The caliber is not picky and shoots about any boolit great. I have made several molds and have shot 5/8" groups at 50 yd's and less then an inch at 100.
I am going to have to go to Photobucket so I can post pictures here.
Whitworth has shot at an inch at 50 and a super group at 100 with his converted SRH.
The Lee 400 gr boolit shoots real good with 26.5 gr's of 296 and the Fed 155 primer.
296 and HS-6 shines in the .475. Use 15 gr's of HS-6 with a 400 gr boolit, it will do at or under 1" at 50 yd's. Pleasant to shoot too.
Don't pay any attention to the rags with their 25 yd groups. The gun will beat them at 50 yd's.
The Freedom .475 shines with a 350 to near 400 gr boolits and the BFR's don't like anything under 400.

Yes I do.I have just been to lazy to set it up,plus we still have about 20" of snow on the ground.When the snow melts I will put my shooting bench back out and set up my Pact. later,OB

for reduced loads, try trail boss.
I use it with 400 gr bullets @ about 800-900 fps and it kicks like 9mm in my BFR. if you watch closely while someone else shoots that load, you can actually she the bullet slightly as it goes through the target.

Sounds like you got a great gun.
You don't have to run it full throttle all the time. It is fun to shoot the huge loads, but a 400 @ 900 fps can be fun to plink with also.

If you load the 475 to the same cartridge length as the 480, you should have the same usable capacity. Also if you load the 480 to the Linebaugh length you should have close to the same capacity. This may open up more sources of load info.

I really like Quickload, it is really handy for getting a second opinion when you're wanting to load where there is no load data.
You still have to use your mind and ask, does this sound reasonable?

If you're not casting your own, Mt. Baldy Bullets has a 405gn Keith style SWC for the 475, and only $30 per hundred.
They are great people to deal with.

I have been sent many different Keith style boolits to try. Some great guys have sent many boolits of all kinds and weights.
In every case I can't match the accuracy with any Keith boolit in ANY of my guns from the .44 up. Don't get me wrong, they shoot decent but will group about twice as large as the LBT style.
I have had groups down to 5/8" for 5 shots at 50 yd's with the .475 and groups to 7/16" with the 45-70. Bruce B's, Dubber's, Mountain Molds, Lee molds and my own mold's boolits.
I have not found a boolit the gun won't shoot EXCEPT the Keith. I have some left and keep them around just to look at, they are pretty boolits.

A question, BFR: is it possible the Keiths you are shooting are going plastic due to either velocity, twist rate or maybe too soft an alloy, and maybe a combination of all of the above?

Just wondering, as the Keith has always been very accurate for me in all my magnums. But I will readily admit that I can't shoot them the velocities the "super magnums" like the 475s, 460s, etc. can...

No, they are very hard. Even the RCBS, .44 boolit, cast hard and shot with light loads does not give the accuracy it should.
My feeling is that if it does not engage the forcing cone dead center it depends on the small edge to center itself.
Cast soft and driven hard can slump the nose, no support.
If you are happy with 2", 50 yd groups, I guess they shoot OK.
