Lyman Borescope

[Ggmac]

You install the diff color 1-2" in front of the lens , light , so you would actually sandwich the defect your looking at . A dif color sometimes makes a world of dif . I would ask that you have someone with a Hawkeye to verify its safety before shooting .
I've got 5 bore scopes and have been using them for 20 + years , color can add a whole new dimension to determining a crater or mountain .
Your is def a odd duck , it looks like liquid metal , I use to see this in old black powder (original ) barrels when owners used Mercury to remove lead or whatever they believed it would do .

Don't know but everyone who just got their borecams has discovered their barrels are crap.

One thing we have to remember is that the accuracy of the rifle is all that matters. If your rifle is still shooting 1/4 MOA or less, what's the difference on how the barrel looks when you see it for the first time? Wear and tear is inevitable. I think of a borescope as a troubleshooting tool. Take pictures of the bore when accuracy is good, then later when accuracy starts deteriorating, compare new pictures to see if it is a wear issue or a cleaning issue that can be corrected.

If you look at the design of this Lyman, there's the aluminum tube, with a notch cut about 1/2" from the end, with a mirror mounted at a 45-deg angle inside the notch. So the tube nearly blocks the bore on both sides of the notch in this 22-cal bore.

If I insert the Lyman from the breech end to view the chamber neck area, the tube beyond the mirror is in the bore. I can feed an LED light source all the way down from the muzzle end, but very little light will get past the end of the Lyman, at least in a 22-cal. bore. It's worth a try, though.

The gun has been fired many times, with hot 22-250 loads (40-gr bullets, lots of powder behind them, ~4000 fps). You can see the fire cracking for yourself. But it's hard to imagine this "blob" forming after manufacture, if it is steel. Since it is well past the end of the case neck, and not "tall" enough to impede a bullet chambering into the lands, it probably has no real affect on functionality.

Well this gun was not a 1/4" shooter, at least not for the friend I got it from. But it would shoot < 3/4" for the most part. It should do better IMO, but I haven't yet started load development for it.

The design is not new , I'm referring to reflecting light of of the insert . So you would insert the color from the muzzle ,to within 1/2" of the blob , insert your scope brom the chamber having the " blob " between the 2 , the choice of the color will reflect and change the appearance , try it , green and orange or red .

I should not have said opaque , maybe that's the part that's confusing . I use colored paper .

Tracking number for UPS says my borecam from Grafs should be here today. Pretty excited to see how it performs.

Ok, I'll give it a try. They sell 3-ft hardwood dowels at any craft store, in various diameters, I can simply smooth up and paint the ends of one different colors and run that down from the muzzle.

Has anyone found a case for these?

Smart money says Remington and Savage are in for a ton of newly dissatisfied customers ....compliments of a working mans priced borescope.

Yeah but like I said, if it shoots, it shoots. I have a Shilen CM barrel that is so rough you can never remove all the copper from it. Just too many tooling marks. So bad that they are plainly visible to the naked eye from the muzzle. But it has shot groups under 1/2" at 200 yards and has never shot a group outside 1" at 200 yards. I'm sure that barrel will look like hell when my borecam shows up and I get a closer look, but as long as it shoots, it's condition won't bother me.

Just got my scope. Don't see anything wrong with using the original box as a case. Everything is protected with soft form fitting foam. Not sure if they all came this way or not, but I don't see the need for an aftermarket case.

On another note about portable power supplies...

The output power of the power supply is 5 VDC via USB which is exactly the same as a smartphone wall charger. So if you go to Best Buy or Walmart and pick up a rechargeable cell phone power pack with USB ports, you're in business. A good cellular power pack will run you about $50-$100 if you want a good one that will last a long time. I already have one of these I use for traveling on planes so Im good to go. Below is a picture of the scope powered with my cellular power pack. Piece of cake.

The box is nice, but a) it's not water resistant, b) it doesn't latch shut, so if it got knocked off a bench it might spill open, so you'd need to put bands around it, c) no carry handle.

I'm ok without a case, myself, for the price.

Here's one at Best Buy for $60, there are many cheaper ones (< $20) but this is probably the entry for decent field specs:

However, beware - these power banks come with different type USB ports, for example this one comes with a 2.4A and 1.0A ports, to handle different class devices, so we need to do a little more homework to identify what the Lyman will be happy with:

RockyMtnMan thanks I have one of those chargers I'll give it a try, Thank you

Here is a close up picture of the power pack I use. It is made by "myCharge", model AMP60K-A. Paid about $50 for it. Capacity is 22.2 Watt hrs, has dual USB ports, power level indicating led's, and flip out 120VAC receptacle prongs for recharging the pack. Lasts a long time and fairly compact. To give a size reference, its a little smaller than a Leica Rangemaster LRF. I highly recommend this unit. Really good quality for the price.

I gotcha. As of right now, probably have to be a custom job built by yourself or someone else. With the instant success of these scopes on the market, I'm sure someone is bound to produce a nice hard case at some point in the near future. I'll keep my eyes open.

The Lyman power supply is rated at 1/2 amp and I'd be surprised if the scope uses 1/2 of that. So, the above power packs would be fine.

Good on Lyman for making these borecams utilize such a universal power source. They were really thinking about keeping things simple and inexpensive in every way when they built this wonderful scope

Great clarity on mine as well. Not quite as clear or bright as a Hawkeye due to monitor limitations. But dang close. Worth every penny.
