Thread: DIY bullet tips for flat nosed cast bullets

Being such a wet and crappy year it's taken me a while to get out and test. OK, so mixed results. I did get a flyer that I believe was caused by a tip coming off. Wasn't happy about that.

But the BC data from the labradar was sufficient to give deffinate results for each shape.

I sent 10 normal NOE semi flat nose bullets downrange and got an average of .250 G1. Not too shabby.

The home made pointies did noticeably better with an average of .285 G1.

The blob tips were a disaster and I stopped shooting them. I believe they were .256 but I had climbing velocity due to residue in the barrel.

Those results were all over the show but for .05 gain in bc... nah the blobs are a waste of time. But the pointed rounds I feel had merit. The accuracy was good. I was forced to only shoot in 2s as this rifle doesn't like heat at all (SBL 45-70).
I also need to check I didn't kill the scope lol. Testing for another day.

So this would be using the keith hollowpoint mould and avoiding the mag tube. Single loading only. Gonna jump on an app and see what gains I would get on applied ballistics using those bc results (they worked out pretty well when I ran them out to 200m last time and took real world drop data

OK so feeding all this crap into strelok to get the suggested hunting zeros it came up with a very interesting result.
The flat tip bullets are best set at 106m giving 86m of "flat shooting". They drop to subsonic at 285m.

The pointed rounds are best set at 116m zero, giving 115m of flat shooting. They go subsonic at 365m.

(The flat shooting distance begins at 20/21m for both). Strikingly similar tradj to a .22lr really when you look at it. But my original aim was to get 50m extra usable hunting distance. 29m is what it turned out to be. So a 33% gain in killing distance. 28% further supersonic flight (you can't actually rely on those full distances as anything transonic / near the sound barrier can lose stability apparently)
