mountaingunRe: Are "we" everywhere ?????
Aladin,
I enjoyed your exchange with that other distinguished moldmaker at that other forum.
There is a lot of truth in what the distinguished mold maker said about the drawbacks of bore riding bullets. But the real reason went unspoken --
because 2-diameter molds are more difficult to make, owing to the tight tolerances required. A 1-diameter mold can be made oversize, and the bullet sized to fit, but a bore riding mold has to drop out darned near perfect. Tight tolerances do not come easily, not even to distinguished moldmakers.
In an earlier thread, the distinguished mold maker was a little more candid. In that thread he admitted that he no longer made bore riders because "two diameter rifle bullets .... were killing me time wise."
Likewise, there was a lot of truth in the discussion of aluminum as a mold material. But the real reason went unspoken.
Because aluminum is easier and faster to machine. Honesty counts for a lot in my book.

aladinmountaingun I was aware of those facts but my intention was to leave said 'maker with some wiggle room.
Methinks your leaning on the riders too for some of the same reasons.. I mean it HAS to be a major main to cut them indentical. But the pure fact remains.. the rider rules for groups in BR. But for all the 'know-edge' of the BR boys, methinks the same thing happens in that venue. Someone stumbles into a combination that just works... for whatever reason and they fly with it. I do think a spitzer fitting the throat and used with what I'll call 'zero rudder' clearance could do same. One of the bullets Gray shot back when was an Eagan tapered nose pour which amounted to a spitzer ogive albeit with the nose pour flat.
Another point I forgot to de-tale in a thread speaking to the BR accuracy. This is accomplished with the one case method of shooten. Load and shooten one case for the whole string. Sure points to variables in the case for consistency with cast.
Agreed on holding some semblence of reality around Veral's 'forum' which in reality is just sounding like a continuous talking advertisement. He don't walk on water and he's dated somewhat for accuracy.
What you makers could employ is the DD design.. Simplier to cut and makes for easier extraction in tight situations. I'd tap ol' Veral with that one but seenig as another maker claims to have originated it... he's just ignore or scratch dung on the idea. Course I might suggest it anyways....
