Ok I have a problem for you 204 ruger guys, I went out to sight in and 204 today and came across something thats got me at a stand still.

I loaded up my 204 with this load
IMR 4895 26.0 GR
40 GR HORNADY V MAX
PRIMER 205

I got it sighted in @25 yrd with an inch high
ok now this is where it goes bad , at a 100yrd I am 10" high why? what did I do wrong? I messed with it for an hr and got pissed.

any help please?

If your scope is mounted high above the bore this might be just fine.

Sight it in for 100 yards and see what you have at other ranges.

Stranger things have happened.

According to IMR your load should be about 3400fps.

Using "Point Blank" ballistic software and assuming your scope is 1.50in high, your 40gr bullet at 3400fps sighted in at one inch High at 25 yards will be almost 8in high at 100 yards.

To be 10 inches high at 100 yards your 25yard shot would be about 1.75 inches high.

It seems to me that your gun is shooting pretty close to where it should be.

Ok I thought I was off my rocker , I talked to about 10 others saying the same thing so I am ok , glad to know I am not lossin my aim.

Thanks Guys

When I use 25 yards as a beginning point in sighting-in, I actually want to hit exactly at point of aim. Then I make any adjustments when I get out to 100 or whatever.
A 10" difference from your point of aim at 100 could put you off the target. Then you're lost until you start over.

If your rifle is a bolt action, I have had best starting results by bore siting through the barrel to align the scope at 100 yds and finish by firing, when I get impact on the target, (this is important) using the EXACT AIMING POINT AS THE FIRST SHOT, without moving the rifle adjust the crosshairs to align to the point of impact, the next shot should be center so long as you do your part. It is a pretty simple method.

Unless you know the real speed of your bullet you are going to continue to "get pissed". Because without some good data from a chronograph and a balistics program it's a poor guess at best.

Mostly you should be about 2" low at 25 yds. to be close at 100. This is relative to scope C/L vs. bore C/L and will be dif. in all rifles.
