Re: 500 yard group

In theory your groups should be 1.25" but that is rarely the case. Even if all outside factors are non-existent. It greatly depends on bullet stability, velocity, BC and many more key factors. If it was more than 1 MOA at 500 I would be suprised. Figure on 2-5" That is without any wind.

Get out there and try it.

Re: 500 yard group

a lot of theries and stats out there. I feel that it comes down to this...your ability every rifle is different. It may shoot like a house afire at 100 but go to pieces at 300 and sub MOA at 800...

bullet quality, type etc. play a big part as well...

Re: 500 yard group

As a regular benchrest competitor at 500 yard Grooundhog matches...the answer is "NO"....there are too many variables to ever make that logic work...my 6PPC will shoot .100's all day long at 100, but I've never gotten a sub 2 inch group at 500..and I've been doing this for 10 years and I've seen lots of groups at 500 yards from everything made on this planet and have "NEVER" seen one below onch inch..easy to talk about and B S about but very difficult to do...

Re: 500 yard group

When you say that you have never seen one, are you talking
about a 5 or 10 shot group or other ?

Re: 500 yard group

It is possible, I have done it... less than an inch at 500. It wasn't luck and the rig shoots bugholes in good conditions. Testing for drop I fired a group at 300, 400 and 500 yards (3 shots) consecutively and groups were (at 300 I forget???) but about 1.1" at 400 and .980" at 500. The 300 yard was very small, smaller than the others I just forget but, it's on the pic I took of the targets some place.

I've shot several 2-3" groups at 800, and a nice 7 shot group at 600 once with the 200gr Accubond random load that measured under 2.5", one was a flyer 1" out to the right too, so really it was a 1.5" and a flier for the whole story and those were fired super fast before dark 30 just to compare the drop to the 210 JLK. This is with the 28 lb. bench rifle in 30/338 Lapua Imp.

500 yards is 5 times as far as 100 yards so group dispersion would be five times that of the 100 yard, or 1.25", in perfect conditions. Due to wind, velocity and other variables I factor in about a 5% increase in group size for every 100 yards beyond 100, 20% at 500 and 45% at 1000 seems reasonable and fits pretty well with my experience.

In a nut shell, I believe a rifle is capable at 500 yards to hold it's 100 yard level of precision, I've just seen it too much, but still figure on the 5% per 100 rule.
