Scope Field Eval Explanation and Standards

[Axlrod]

My thoughts on it, are why overthink it? There is a good data set on quite a few scopes that work. Why spend money on ones that work sometimes?

I practice at 3500 to 4500 ft I was wondering if there is going to be a noticeable difference when I go to hunt at 6000 to 7000. Far as needing to add or subtract my come up. I have ran it in my ballistic app and fro. 0 to 600 it is only a 2in difference was wondering if that is true.

You answered your own question, a good ballistic app doesn’t lie

10 4 I use the 4dof and it's been good to me so far

It’s a good scope. If someone wanted a 3-18x’ish scope with a tree reticle that’s the one I would pick in general.

For hunting, it doesn’t do anything that, so far, the Maven RS1.2 doesn’t do better.

Sir, I've been reading your posts and your test reviews, much appreciated for those, but I am looking to buy a new scope. I would like to find one I could use in different terrains and at different distances. What would be your first recommendation? Thank you.

Without knowing more details- the best general purpose hunting and shooting scope on the market is the SWFA 3-9x.

Sorry about that. Ranges would be from 100yd up to 900yd. I’d use it for deer here in different parts of Texas and I plan on going Elk hunting next year in Colorado. My rifle is a 6.5 PRC. Thank you.

SWFA 3-9x would be my first choice. SWFA 3-15x FFP Gen 2 would probably be my second choice. Then the Maven RS1.2 SHR-Mil.

Thank you sir. I really appreciate your insight.

What changed to push Maven to 3rd?

For me- the ease of the turrets spinning on basically anything.

My swfa 3-9 turret gets sticky/mushy. I think it’s something with the o ring getting dusty as it temporarily gets better after cleaning.

What’s the long term solution for that? Oil hasn’t helped, cleaning with alcohol hasn’t helped… open to ideas!

Pull the O ring out.

Fomblin or other rubber safe silicon grease. Dry gaskets drag

Other than using a synthetic o-ring grease you just take it out and throw it away. The internals under the turret are sealed so nothing is getting into the internals of the scope. You can take the turret off and clean it with a q tip and alcohol if gets wet or dirty. Reality is they don’t really get dirty much at all when you throw it away.

How do the SWFAs compare to the Maven in low light conditions? I just switched to a Maven RS1.2 from a cheap Vortex after following the drop tests and have been blow away at how bright it is even in the final minutes of shooting light.

Thread 'Low light comparison of 17 scopes'

Dec 10, 2024

There are always constant threads of discussions about “glass”, low light use, etc of scopes here. The last couple of week I have gotten many more questions about it (due I believe to SWFA being back in stock), so while working with a couple of scopes on other things, I brought out 10 different ones (6x day, 10x low light) to see what difference there is.

Eval #1 was daylight:

1). Trijicon Tenmile 3-18x44mm- 2 years old, more than 5,000 rounds of use.

2). Maven RS1.2 2.5-15x44mm- 1.5 years old, more then 3,000 rounds of use

3). SWFA SS 6x- two years old, 2,000+ rounds through it...

That should give you an idea.

Impact Force from Falling Object​

Even though the application of conservation of energy to a falling object allows us to predict its impact velocity and kinetic energy, we cannot predict its impact force without knowing how far it travels after impact.

If an object of mass m=kg is dropped from height h = m, then the velocity just before impact is v = m/s. The kinetic energy just before impact is equal to its gravitational potential energy at the height from which it was dropped: K.E. = J. But this alone does not permit us to calculate the force of impact! If in addition, we know that the distance traveled after impact is d =m, then the impact force may be calculated using the work-energy principle to be Average impact force = F = N.

Note that the above calculation of impact force is accurate only if the height h includes the stopping distance, since the process of penetration is further decreasing its gravitational potential energy.

The average impact force calculated here is the average over distance, which can be presumed to be proportional to, but not the same as, the average over time.

Old I know but I just had to reply. Just to make sure I understand. If I get Sufflexed or power slammed by Wahoo McDaniel, you have to know how high I bounced, to calculate my impact force.

Sufflexed

Suplexed

He'd revert back to old times and give you the sufflex (lol) of the punte, using you to score 3 points by drop kicking you through the goal posts. And to think, you wouldn't have to sell it in the slighest.
