Need some help from "Bullet Math" guys

[JWFilips]

Well That Long NOE 65 grain MX bullet will shoot in my 1 in 12 twist. I was very surprised and very excited!
Didn't have any loading data so I just picked 10 grains of 2400 ( Well my drop really was 10.1 grain) Picked a COL to have the nose snug in the throat
Loaded 10 up and tried them today
My first shot out of cold barrel went right and at 2 o'clock ( I also pulled the last shot ...never fails! 5 o'clock bottom )
I weighed these out at 65.4 gr

Also fixedthat plain base problem with the NOE 55 ( Which weighed 62 gr)
I just washed off the lube with naptha and annealed them in the 400 deg oven with a long slow cool down. (Now BHN 11-12)
Re-lubed with only one coat of BLL since that was all the time I had
From not being able to keep them on the backer board last week to this this for 15 shots Seems like in my rifle "soft and slow" is the way to go

Nice shooting Jim. Yep, I've heard that before, wuss loads softer alloy, diamonds not needed. "Hardcast" causes more problems than it could ever solve. Is only useful for commercial caster to ship their product and pollute the minds of those without the experience to know better. Harder bullets can have their place but light plinking loads and most handguns ain't that place.

Rick,
I knew that Dance many years ago when I started shooting "softer" "fatter" bullets in my pistols... The pistol range crowd were in an uproar! Especially when I started shooting commercial cast "Cowboy Lead " in my 40 S&W! I started to outshoot all my pistol buddies & they refused to accept the concept.
I guess that's why I have laid my pistols aside and only shoot cast in rifle now!
On our rifle range; I'm that "Special guy" that Shoots Lead bullets in his rifles!
Not much respect but at least I have a "Title"

I have just about that same title.
I think it's 'that nut down there that's always here shooting cast bullets and blowing our stuff on the ground with his muzzle brake'.

 

[Ian]

Yeah, you must be a nut to push cast fast enough to make a muzzle brake work

I got run off a range once after cutting loose the first full power paper-jacketed .308 load. The RO couldn't get his head wrapped around the fact that I hadn't just shot a cleaning patch out of the barrel even after I showed him a loaded cartridge, and everyone on the line was totally freaked out by the confetti. Actually I didn't get run off, I just left after he said something like 'that's only safe for black powder". Whatever.

Jim, now you see what we were talking about with matching alloy more to the load you're using and also about stability and twist. Greenhill says you're borderline, but as we know "thresholds" are meant to be stepped across. A pointy or hollow pointed bullet will exceed the lower end of stability limits Greenhill predicts by a wide margin whereas a wide, flat nose or wadcutter not so much, so keep that in mind.

hey now.
I even got the muzzle brake on the 300 b.o. to work.
I have it clocked all wrong and it throws the sound from the blast all over, except it seems down range, but it indeed works on the 16" barrel.
the sound thing actually works in my favor out in the field, I have had rabbits hop over to check out the dirt puff when I mis-calculated the wind, rock chucks do not give you the second chance.

There are a fair number of members of our club who shoot cast. They probably shoot a lot more jacketed than cast, particularly in rifle, but a goodly number shoot cast in the pistol pits.
The more I shoot primarily cast on the range the more I run into serious casters. It is however a club with a large number of members with folks who are interested in just about all forms
of shooting. We are fortunate to have a club with such excellent facilities, and range officers on duty to keep folks aware of a number of factors, but primarily of safety.
