Hey guys,

Has anyone seen a lead bullet mold for a 470 nitro? I could paper patch but that's kinda a pain. I would use them for deer etc with a 75% load. Any if you guys here have one that I could buy? Or, anyone have some ideas for cheap loads? I know they won't regulate but they are for my younger boys. Even pistol bullets like 475 linebaugh loads. 400 grain or better. Any thoughts guys?

To use the 75% Rule you'll want a 350 grain bullet for it to regulate not a 400. It's 75% of the original bullet weight. In you case with the 500 grn. makes it 350grn. for the light load.

Mike is right! The way the 75% rule works is, you use the normal full powder load, but substitute a bullet that weighs 75% 0f the weight of the normal bullet used in that chambering. With the 500 gr bullet for the 470NE, the actual 75% weight would be 375 grs, however a 350 gr bullet will work with just a little powder adjustment!

Brooks... You are right on that one. Or I Could run 500 with 75% of the powder charge I do believe. I won't have the rifle for another 30 days as it is but I'm trying to get things squared away so I'm ready to play when I get it. All though, if it doesn't regulate....

Sean, to find if the 75% bullet weight works, if you have a factory round simply pull a bullet and replace it with a 350 gr bullet, and see how it shoots. I'm not sure the 75% powder with the 500 gr bullet will work, but I suppose it is worth a try! The idea of the lighter bullet is to reduce recoil, and save money by using cheaper bullets and still get regulation!

Using 75% of the powder load doesn't fit the 75% rule and with some powders in some cases can be dangerous. (I don't know about the 470, or its powders.)

Best to find bullets or a mold or have a mold made for a ~350-375grain slug.

I have shots lots of pigs using the speer 400 gr gold dots in my 470,I use R 15 & my load was a few grains short of the max with the 500 gr bullets,they regulated perfectly at about 2200fps.

Good advice guys. I'm new to the DR stuff... My big bores are bolts so trailboss for the kids and a sight in and that's all there is to it. These buggers are different. If I don't blow myself up, it should be fun!

Bill, that's like having a 470 that you can turn into a 450/400 ... Roughly. What powder do you use?

Fellas:
From my own shooting with doubles I have found using the 75% rule with lead bullets pushes them too fast and causes leading in the bore. I have done some experimenting with the 75% rule in reverse and used 75% of the powder with a full weight bullet. Accuracy is not as good but acceptable and better with lead bullets as the bullet is moving slower. Most of my shooting as such has been with my .600 but more work will follow this summer.

BUT, shootaway tells me this will work with other calibers and he is the Guru of all things double. Just ask Mikey.

Cheers,
Cal

Thanks cal. I had heard that also, obviously. Only what I read on these forums... Remember, no DR expert here! I'm sure everyone can and would have different results from rifle to rifle as well. No hard and fast rules I'm sure but I can go both ways with it. Anyone have success with trailboss powder or is that not going to get even in the ballpark? I haven't looked up the data yet myself. I know trailboss can get funky if you compress it... Not a good way to fly.

Yeah, I got the intro to all the things that Snotaway knows and doesn't right off the bat. He is quite smart... And cordial also. Wonderful chap. Only guy I know that could go to take a leak, hold his thumb and piss his pants.

If you are going to try using a light powder load, please do your research. There are some powders which become unsafe with light loads. Read up on the powders you wish to try and make sure they don't have a light load warning. Some of the powders I use for my doubles do have light load warnings!

Bill is using R 15. You will find some data here on this forum, but some in a couple of manuals too, including Barnes. Graeme Wright's Book, iirc, "Loading for the English Double Rifle" will also give some tested data.

Sean, Keep in mind that the mukuluk telegraph says Cal and shothiswad are first cousins. I'd be very leery of trying this in your own rifle.
I'm very certain that the new guru of the DR's will set us straight with his vast store of self proclaimed knowledge very soon. ( Not that it'd be correct or even close to reality in this time space continuum or possibly this dimension. )

Trailboss also works well for greatly reduced loads in doubles. Regulation is usually off a little, but for target practice and pigs and such, it's great.

I used R15 with foam filler in all my loads,I have had two DR's in 470 NE,the first a Merkel,I shot cast bullets only in that gun,because it only went with me to Texas on pig hunts,the cast bullets were gas checked,I did not experience any leading at all,incidentally that Merkel just took an elephant in Zim this past november in the hands of a very good friend,
My second 470 is a Heym,this gun goes with me to Africa,I use the 500 gr bullets for big game & the speer 400's for warthogs etc,there are plinking loads available for the 470,I believe Butch Searcy has a very mild load with 5744,I however found that reducing bullet weight served my purposes quite well,& I still had a load that worked in the field for me.
