Need help with a load. I need to see what a 160gr ftx bullet does or doesn't do at 1,400 to 1,500fps.
I have everything from full power down to about 1,700fps covered. Less than 1,600fps gets tricky.
For full power 2,150 to 2,200fps I'll use leverevolution.
To get 100yd velocity of about 2,000fps at close range I'll use a start load of 748.
To get 200yd velocity of 1,800fps at bar fight distance I'll use a middle load of IMR4350.
To get 300yd velocity of 1,600fps at close range a start load of H322 should do.
To get 400yd range of around 1,450fps could be a little less than a start load of IMR4350, maybe around 29 to 30gr of N555, maybe a less than start load of H322. If they won't expand satisfactory at say 400yd velocity I'll abandon that idea assuming they expanded satisfactory at 300yd.
And I'm open to suggestions?
I have heard too many stories of people trying to fire from brass with way under start loads of ballpowder and their gun blowing up so not doing any under start loads with ballpowder. Down loading say 748 to get 1,400fps could do unexpected things.
If 400yd expansion surprises me I'll think about a 500yd velocity test, 1,300fps that doesn't seem like a real possibility now, I'd probably be looking to use something like unique, HP38, CBI at that point.
And don't say shoot the target at 400yd. The range I go to to shoot over 100yd is unavailable till summer time.
There's one shooting area there, targets go in the same spot regardless of shooting distance, you move further back as needed out to about 700yd.
When the range opens up I only want to do the live tests at 300 or 400yd I don't want a bunch of "pristine bullets" laying around from say the 200, 300 and 400yd test that could contaminate my findings.
