Please describe the rig you are getting to 500 with. I would be interested to hear how much up you had in your scope to get that far. JS aka 308
There's a very good reason why the flaps on .22 Rimfire ammo are labeled "Dangerous with 1-1/4 miles".
On a similar note. I was out testing bullet penetration and weight retention at 200 yds in wet news paper. After I was finished I shot one shot with my 10/22 with American Eagle 38 grn HP. Made an elevation correction and did a double tap. Drove out and started peeling layers of paper one bullet had penetrated 8 inches. Paper was packed pretty tight in box. HP had failed to open probably due to loss of velocity.
3000 WSM 150 grn .308 Fail Safe pushed right on through 16 inches of wet paper with a 3" exit hole.
I was just wondering because I have a 10/22 w/ a leupold vx3 4.5x14x40 that has about 125 minutes of elevation and about 100/thou of up in the base and while I have been successful getting to 400 on steel I have not registered any 500 yard impacts.
Still its pretty cool to know they will get to 500 and still have enough left to flatten out like that. JS aka 308
