460-350 ranchdog plain based

[Roger Allen]

Hey just got this mold for my guide gun.

Was thinking about powder coating it.

Anyone like this mold plain based?

I'm going to use imr4198 and going to try for 1700-1800 fps or so

 

[Ian]

You'll likely need to powder coat it if you want to go that fast with accuracy. The question is how deeply you'll have to seat it to chamber after coating, and how much you will need to reduce your loads to account for reduced powder space.

 

[Roger Allen]

It'll seat about .1 shallower inside the case compared to my 405 gr.

Just asking if anyone has gotten the plain based version and liked it enough fast.

I've done fast and plain based before...mostly w 30 cal and powder coated and my buddy does it without powder coat w his 475 Limbaugh

 

[Roger Allen]

Oh and the nose length is same as my 405 gr and at the crimp groove I still can obtain the Marlin coal in my 45-70

Checked on ranchdog and his data and length of coal and my coal will still be in compliance

 

[Brad]

Never shot a plain based 350 RD. Fired quite a few checked though.
1700-1800 fps with a plain base is gonna be tough. Very tough.

 

[Roger Allen]

I bet it could be done powder coated

 

[Brad]

I bet it could be done powder coated

Only one way to know, isn't there? Let us know how it goes.

The 350 RD is a great design.

 

[Roger Allen]

I promise!!!

Good news is I've done similar big bore pressure plain based in 44 mag pistol w no leading but 200-300 fps less

I have shot a 405 gr plain based to 1500-1550 fps but not the same pressure.

I've shot 50 yard 308s at 2200 fps plain based and got ok accuracy 2 inch

I'm pretty certain I can come up w something resembling success

Have you already tried to chamber this cast bullet in your rifle with the OAL you describe ?

Ben

 

[Roger Allen]

I have not. I have to wait til this gun gets back from Marlin as they may be putting a new barrel on it. It's kinda in limbo right now

 

[Ben]

The reason I'm asking is " assuming " the OAL that Ranchdog offers is going to match well with the throat of your particular rifle may be " assuming " a lot ? ?

I have this particular bullet and load it in my own 45/70 Siamese 98 Mauser. The front drive band may fit your Marlin just fine, it was too large for my particular rifle and it caused me to have to deep seat the bullet.

Just asking if anyone has done this bullet this fast before.

Do understand that there can be a problem w seating depth. Pray to god I don't have to worry. I saw your loading yours lighter than I was going to....searched back a lot to find your post and others like it.

No one seems to be shooting this bullet powder coated at velocity near lever gun levels plain based.

 

[Ben]

Good luck with your goals.

Ben

 

[Brad]

I have never powder coated and have fired less than 50 powder coated bullets ever so I am of little help here.

 

[Ian]

Good opportunity to contribute to the edification of the hive mind here and for all the lurkers, too. Lots of ice been broken in these parts, sometimes you just have to jump in with both feet and share what you learn, the good, bad, and ugly.

 

[Roger Allen]

Promise promise. I'll take Picts. It'll be about a month before she gets her new dancing shoes

 

[RBHarter]

Not the RD bullet but a Mountain Moulds 453-350 .
PB and greased in a 45 Raptor I was tipping into the high 1600s with H322 . Since it is a 1 off rifle I need to make some adjustments for seating in the throat and some improvements to sight mounting .
On my list of adjustments to make to the load will include a wad card (paper gas check) . I may try 4198 if I can get another lb . A 20" barrel over the 16" now on hand would I'm sure get it we'll into the 1700s .

I've become a fan of long flat curve , slow powders for most of my cast shooting . More so where naked bullets go .

 

[Roger Allen]

Ok I have a report but no Picts, just trust me as this is a great moment for my cheap self.

Bought the plain based version of the 460-350 rd because I don't like buying gas checks at all.

Loaded in a 1895 guide gun 45-70 4 shots each load (very punishing) all shot w .460 sized bullets powder coated and powder used is imr 4198


40.0 1 1/4 inch
41.2 1 1/4 inch
42.4 1 inch
43.6 Threw my 4th shot disqualified
44.8 1 inch

No leading at all but I believe I have reached its limit at 44.8 gr imr 4198 at 50 degrees outside

My Lyman manual says that this flirts 1936 fps and 27 k cup in a 24 inch barrel.

"long flat curves"... If I'm conjecturing it right,applies to trajectory as well.We see it in archery.Would you rather have a fast flat curve for X amt of distance?Then,drop like a rock.

OR

Not quite as much speed initially,but "flatter" over the long haul?

I've played,and will continue to do so,on both sides.The more you can define the goal,the easier it is to... "pick one".Both have purpose.BW

 

[Ian]

No, he was talking about powder pressure curve, like draw force through the range...recurve-curve and compound eccentrics are a perfect analogy. Trajectory curves are only affected by ballistic coefficient (WFN bullets being, well, close to "unity"), all else being pretty much a constant on this rock.
