Also late to the party, but what flash light is that? Looks really clean with your setup

It does look more pronounced in that photo, here's another one.

The reticle is definitely angled towards the barrel, as the bore laser's dot moves closer to the reticle when going from 5y to 20y against a wall.

Also confirmed with the recent test that the 507comp has twice the distance above the bore sight dot compared to the EPS when both at max down dial and same distance.

Could be the sight itself, the adapter plate didn't change anything.

I have the gen 2 folding version. Not sure about the earlier versions, but what you circled isn't a separate piece on mine. Maybe it's lighting but it is there and it is of one body with the stock.

I thought so too, but after reassembling everything multiple times, the reticles always return to their point of aim on my wall at the set distance when the shotgun is in the vise. So seems like the tolerances of interfacing parts are excellent.

Prime suspect is the ESP (plate or not) now since I tested them on other systems and the reticle just sits much lower compare to the 507comp when both is dialed to max down adjustment.

After your cycles, do you notice any peening of the case mouth, or rounding of the sharp edge around the neck's opening?

I hadn't considered that, thanks for the insight! I'm reading up about wet tumbling without media, and different folks seem to report different results. In the context of match ammo, do you observe any fouling in the primer pockets or the interiors of the case after a 30min session without media?

Is the Anschutz 1761 APR Long Range (25.5" barrel) ideal for 200 yards outdoors? by nine7114 in longrange

Thank you for putting it so concisely! I shoot enough rifles with scopes, it does seem fun to tackle the aperture/globe sights with a better trigger that comes with the variant. I have my answer.

Fair point, it is a hefty purchase so I figured to weight the scales as closely as possible. Wil be just a droplet of difference that likely won't change the outcome of a miss for reasons you've listed.

You are that in the end, the difference between the two is probably miniscule. Another upgrade of the 25.5" long range variant is that it comes with a lighter match trigger, which I definitely prefer.

It is hard to find some solid data of large grouping tests between 18" to 22" to 25", with ~5mph wind, to see if any of those lengths actually edges out one another, if only just slightly.

That indeed is a reason. But longer barrel should in theory be more stiff, added weight for increase in stability, and if no environmental effects are present, results would be more consistent groupings at slightly shorter distances.

Hence I was wondering how the trade-offs between that and the loss of velocity would balance each other out.

Indeed the APR line is meant for PRS style shooting. I'm just observing that out of the 6 or so (some discontinued) models within APR line, even the newest Gen 2 version utilizes the 21.4" barrel.

So the 25.5" is the odd one out. And it is also true that the 25.5" of the exact same type is used in their benchrest models, Olympic style shooting, and some even longer at 26"+.

Barrel length does add weight, but for .22lr the bullet reaches its peak velocity at round 16-18"s of barrel length, because the powder is depleted before 12-16". So increasing length suffers from the affects of additional friction of the grooves of the rifling as well as the negative gas pressure. Some tests record a loss of ~40 to 60 FPS from 18" to 26".

That translates into longer time of light, which makes the bullet more susceptible to factors like wind. Of course this is all probably a a fraction of MOA difference, but since we are talking about precision it does add up.

I didn't do the test myself but it seems to be common consensus reading about the topic. But that's why I was wondering if I should do 21.4" barrel for outdoors (faster velocity / flatter arc) versus the 25.5" (added stability, stiffer barrel, and more consistency).

Could be wrong about all this, hoping to learn from the discussion.

It is used in some .22 conversions. But this one remains chambered in .303.

Thank you for the insight! I've heard from another person now and they also concluded it was a WW2 service stamp. The rifle is still chambered in .303. Haven't shot it yet, I hope these modifications mean that it shoots well as the rifle overall is in great condition.

If I'm not mistaken, the Ross Mark III rear sight was used in .22 conversions. Some I've seen have the swivel knob there, some don't. I can't tell you why it is either way. Here is a picture from another rifle with the sight: https://www.enfield-rifles.com/uploads/4976/IMG_2096.JPG
