The 308 Plan

[Gator 45/70]

Thanks men,When I can get back to the testing it will more than likely be the 180 gr. gas checked for starters.
Probably do a 5 shot sting, But due to fear of baffle strikes after a couple fired minus the can first to avoid keyholing
In other words, If I see key-holes the can's not going on there until I've worked up enough for a nice round hole in the target.

I don't know if these are still around, But at one time Winchester had put out a few sub-sonic jacketed 185 grain rounds

Friend of mine had gotten a box from the rep, I pulled 1 apart and weighed the donut shaped powder.
I want to say 10.8 grains of possibly bullseye powder?

Any other donut powder out there besides bullseye?

One of the advantages to a cast boolit over a jword is that in theory anyway you ought to be able to get a heavy boolit at a shorter length. I plan to use a soft (heavy) alloy as well, no worries about leading at sub speeds. Stability is really about length so keeping them short should help.

Bullseye is a flake powder, not a "donut" powder.

Bullseye also is the best choice for subsonic loads in most every rifle cartridge as it ignites easily in larger cases reducing position sensitivity. It also will produce the smallest amount of gas and the lowest muzzle exit pressure; the smaller the charge of any powder for a given velocity [such as sub sonic at 1050 fps] under a given bullet the less "noise" will be made with, or with out, a suppressor.

In a 10" twist 308W I've shot a lot of cast at sub sonic velocity and never had a stability issue even when well below sonic using bullets up through 1.2" (GC'd 311299) in length. Also with WFN bullets you can have feeding issues with staggered magazine fed rifles. I always found the Lyman 311041 (178 gr fully dressed) to be adequate for the job at 1090 fps. Also the blunter the nose , or flatter, the lower the velocity will be before the bullet starts to snap or crack on exit from the suppressor.

Sorry, I meant trailboss,Thanks

Thanks Mr.Gibson, Brain sneeze on my end, Thinking trailboss typed bullseye, There once was a thread on here by Bruce B, May he rest in peace
The old gent was doing a lot of pistol powder testing in the 308's and had posted a lot of recipes.
What ever happened to the thread,My search-fu powers are lacking today?
EDIT,I've located the BruceB thread

Here is BruceB's loads put together by Jack,After looking this over he was primarly in the 1700/2100 fps range on 99 % of his loads.

Very interesting project Bruce was doing

oops, didn't know you already had the 308. Short story, friend's wife (good shot) hit a hog (7 mag bolt gun) couldn't chamber a new rnd before the hog was lost in underbrush. I tried a head/neck shot @ 50 with BO and he ducked it! Unfortunately, last rnd in the mag. Another guy hit 13 of 15 220gr BO sub @ 100 and still never found the hog. Isn't so much the gun shot but the whack when you hit one that spooks them.

Lol, I have poured corn in a row strait back to the stand and waited....Sure enough about 8/9 lil porkers ran out and being pigs they are they line up shoulder to shoulder to eat, I waited until 2 I wanted lined up, Bang went the 308, 2 pigs down 1 shot.

I loaded them up and when I returned to the camp one old man was like, You got 2 pigs ?
Me, yes sir
Old man, I only heard 1 shot ?
Me, Yes sir, I let em line up, Shot thru one and the bullet exploded hitting the second pig in the neck, lung, liver.
lol true story !

wales uk not new zealand

Oh,sorry about that, I hope that's not an insult about New Zealand and all ?

Is there a good number of rifle casters and reloaders in the area?

Only knowing very little about gun ownership in the UK, Like you have to be in a club I think?

Hello everyone, 1st post here and trying to get into casting -

I have the 230gr lee mold on the way, and a similar hope to get a load in a suppressed 30-06 that works for a "quiet " varmit/hog first shot - any experience with what alloys are suitable for subsonic use in this situation? I'm thinking something soft enough to potentially expand instead of pencil thru.

Thanks,
Terry
