Fat bore rider bullet

[JWFilips]

After doing some mold modification on my Lee Mould I finally got a good size bullet to fit the throat of my worn 7x57 1916 Spanish Mauser. But I did notice now that the nose bore rider section is fat and while it fits the throat of the rifle and I have no problem with COL. it is too tight to be considered a Bore Rider anymore since it does fit in the muzzle without heavy engraving.
I was just wondering what are the consequences of this? ...having the entire bullet engrave.
I did try to nose size a few but they are just too fat for that without pushing up a good size donut of lead at the first drive band

if it fits in the rifling without engraving it still isn't a bore rider.

Yep ^^^^^^^^

That's the whole point, it's supposed to "ride" the rifling. A proper fitting bore rider will engrave the nose evenly all the way around. If it doesn't it isn't riding anything except air and going down the bore it will be tipped to one side. Mr. target will tell you what it thinks of that.

 

[fiver]

oh it will fill the rifling,,, just not quite how you want it to.

sounds good to me my .304. 299PB ENGRAVE ALL THE WAY AND I WOULDN'T HAVE IT ANY DiFFERENT..

 

[JWFilips]

Well this makes me feel better.
When I opened up the drive bands in the mould I was thinking I should have avoided applying compound to the nose section. Some where along the way I lost that thought and ended up enlarging the entire cavities.
Dan yes I do get full engagement now. Just wanted to be sure there were no negative concequences

I would rather have light engraving on a bore rider when it's chambered than none. I don't think the bore rider concept is all bad, but practical experience says that a bullet that is supported even while in it's static state is going to do better than the one that "rides the bore" supported by wishful thinking!

Mr. target will tell you what it thinks of that.

Exactly ! ! Mr. Target always gets the final word.
I've had hundreds of crazy ideas ( theories ) in the past 40 years, problem is that Mr. Target didn't always see things my way.

FULLY ENGRAVED " BORE RIDER"

I want a firmly engraved bore rider also.
the nose of a bore rider doesn't just sit there bouncing down the top of the rifling.
well it does if it doesn't fit but you can see the negative aspects of that happening.
it actually guides the rest of the bullet into place and starts the whole thing turning so the body isn't just slamming into the rifling and then trying to spin.
if it's in there crooked/loose it starts everything crooked or lets it go crooked and once it gets in the barrel that way it stays like that until dirt.
if you hit it hard enough it will slump back to fill up the open unsupported areas, maybe a little more over here, and a little less over there, as it twists on the rifling.

Too much engagement?

 

[Brad]

I don't think so at all. You could have even more in my opinion.
That engagement is only into the powder coating, right? The coating will center the bullet under the forces of chambering but not the forces of firing.
Not if you get to a point where the bullet engraves even a little less than that into the nose of the bullet itself then you have enough.

 

[Rick]

It's too much engagement when the nose sticks in the rifling and pulls the bullet when un-chambering a round. Also too much in a hunting round if chambering is difficult.

 

[fiver]

that's when I add a crimp. LOL

if your really fighting chambering [unchambering] then you got a bit too much.
the throat and the muzzle are 2 different things usually a tight fit at the muzzle is just showing you have a tight fit at the muzzle and gives you an idea what your barrel is like.

all the good/bad happens back at the other end, the first 3/4' is where everything happens.

 

[JWFilips]

That photo is tapped in from the muzzle.
From the chamber it is just noticable. The cartridges don't stick at all unchambering

 

[Brad]

If just noticeable on chambering and they eject fine as a loaded round the. You can still go bigger.
