[QUOTE="proload, post: 515819, member: 34261"] Hi Richard, Thanks for your points / comments. Minor ... we're entering into winter here, so it can rain at a moment's notice ... as a result, I laminated my targets as they tend to rip to shreds if they get wet and I can't analyze them properly when I get home. I shot 3 separate projectiles on the same day (Nosler BT 55gr, Nosler BT 70gr and Scirocco II 90gr). The holes in the targets from both sets of Noslers were as expected. Hole punched through the middle with an even rip/stretching of the laminating material and paper on all sides of the hole. ie it's an even circle. On the Scirocco's, I can see that the hole is not in the center of the rip, and the rip around the hole is slightly (about 1-2mm) exaggerated on one side for all holes. ie uneven circle. I shot about 25 of these projectiles on the day. So in short, Yes I think that there is minor key-holing. Inconsistent. I've done a ladder test, and found what I believed to be the sweet spot. Fired 5 rounds in that zone. 3 rounds group under 3/4" at 100m, 4th blows it out to 2", 5th blows it out to 4" I'm not opposed to trying again with a bigger jump to the lands as I think that that may have been a factor in finding a precise load, but my concern is whether it's worth doing if the projectile is unstable. What do you think. I chose the bullet for it's impact performance at high speed. In other words, I wanted to have a projectile that I could absolutely trust to perform the business at anything from 25m to 350m. Thanks for your comments in this regard. I do appreciate any input that you can offer. [/QUOTE]
