Are there any decent scope mounts for bolt action rifles that arent absurdly expensive?

To answer your question with some questions: what kind of bolt-action rifle? Are you looking non-destructive for milsurp (in which case the answer is pony up for Ste. Marie and deal with it) or just some rings for a 700? Good rings are not too expensive because they're a fairly basic part. What qualifies as absurdly expensive?

Caveat: I have no idea how available/easy to get these would be in the UK/Europe

For separate rings & bases, I like the Warne Maxima series.

If being able to easily change scopes isn't a necessity, the Talley integral bases/rings are reportedly very nice.

So I went on a powered paraglider flight today with a guy that is a mechanic as his day job. He has a sorta junkyard going, and I mentioned I liked guns.

Him: You wanna see a .50?
Me: Cool sure


Me: Umm.. that's not a .50. Do you know if it works?
Him: Eh, probably
Me: Oh, no, never mind, it has been demilled with this big hole in the breech:

Him: Huh, I never noticed that before.

Trying to figure out what this is, figure it is some sort of took pictures of the only markings I could find. Eyeballed the bore as ~40mm.

Is an NRR of 22 really enough? The earplugs I usually use are a 26 in my ears according to the fancy hearing protection test rig at work. They're fine when it's just me shooting, but being a couple of lanes down from a guy with a K98k still seems borderline-dangerously loud. These are tempting, but not if I'd have to wear earplugs under them and defeat the whole purpose.

Most earplugs aren't really designed for impulse noises like shooting. I have a big box of plugs from harbor freight with a NRR of 29. The box says they aren't designed for impulses, but they seem to do fine. I've worn muffs that were rated at 26 I think, and while they didn't have the same rating, they did block out impulses much better it seemed. The ear canal is just the most direct path to your ear drums, sounds can still resonate through your skull. You can really feel the impulse if you shoot something big like .50, which kind of feels like a smack on the nose when you fire.

How does the scaling math work on doubling up hearing protection? Muffs @26 NRR + plugs @32 NRR = 58 NRR, or do you reach some arbitrary diminishing returns at some point and only get an extra 13 NRR from the muffs?

I think you add 10 to the higher of the two. So 29NRR plugs and 24NRR muffs would be 39NRR together.

Well it ain't soy sauce!

Ok, i just acquired three guns. A nylon 66, a Winchester 59 .22, and a Franchi 48 AL (i think), and i have some questions regarding maintenance/repairs.


Here is the Winchester.


Click here for the full 1600x1200 image.


I'm a terrible photographer, but the gun is in fair shape for being 80 years old.


Click here for the full 1600x1200 image.


No patches of rust on the metal, but it does not have a uniform finish. Not really a problem, and as it is somewhat of an antique collectible i don't think i'll be doing any refinishing.

The only problem with the gun is that the firing pin spring is pretty weak, so much so that it will sometimes fail to fire. I'm wondering if anyone can give me suggestions for finding a replacement. Could the firing pin spring for a model 64 be used? Should i take the bolt to a local gunsmith and just have them replace it for $$$?


The other gun i have a question about is the Franchi.


Click here for the full 1600x1200 image.


The internals look like they are in pretty good shape. I had it apart to check things out, and after a good cleaning i'm sure it will be good to go. However the stock is in bad need of refinishing.


Click here for the full 1600x1200 image.


And the barrel is a loving disaster.


Click here for the full 1600x1200 image.

I'm not really sure how to go about stripping the old varnish off in areas that are textured for grip. Obviously too much sanding will flatten that texture out, and i don't want that. The barrel is pitted all to hell, although the inside does not look bad, maybe a small patch of rust near the end. Can i hope to make this gun look less like a tragedy with some brass wool and some sort of cold blue? Does anyone know any good links pointing to someone that has done something similar?


I appreciate any help.

In my experience, plugs are better for thing like being around heavy machinery and other constant loud noises, while the muffs are good for those sudden impulse noises like explosions and gun shots. Either are better than nothing though.

Those muffs rated @ NR22 keep it quieter than my Academy branded NR30. I've mentioned it quite a few times but I think Leight's ratings are more accurate/honest than others.

That seems to me relatively simplistic. Is it something frustratingly logarithmic to arrive at the final answer?

When dual protectors are used, the combined NRR provides approximately 5 - 10 decibels more than the higher rated of the two devices.

To prop the gun up so it can be seen better. Also to annoy certain posters who hate when people do that.

Wee.


I use Pro-X's with foam in-ear plugs. I think the Pro-X's are 18db so the combination with foamies is absolutely required. However, since they amplify voices and other sounds, I can still hear people speaking normally, while the guy shooting his .460 in the indoor lane next to me doesn't bother me at all.

In short, I'd wear both.

If you look at it from a purely math perspective. 26dB + 26dB = 29dB. Every time you double in the linear scale, you add 3 in the dB (log) scale. Every time you go up an order of magnitude (move your decimal place) you add 10. So 36dB should reduce noise 10x more than 26dB. This is assuming that noise is a measure of power which I honestly don't know. If it is a measure of energy everything doubles i.e. 26dB + 26dB = 32dB and 36dB would be 20x more than 26dB.

:eng101:

From a purely math point of view, noise reduction applies multiplicatively, not additively. So wearing two 26 NRR devices corresponds to 26dB X 26dB = 52dB. Basically, you just add the values, since it's a logarithmic scale.

Of course, that's not how it actually works. At my best guess, that's partly because hearing protection isn't ideal (i.e. they don't provide uniform noise dampening across the entire dB scale) and partly because a portion of the sound is transmitted right through your skull.

The best part about measuring decibels is that it isn't really as precise as the +3=double. To be completely accurate you would have to say a certain decibel at a certain frequency, and even then I think it is more of a approximation than precise fit. I'm not a scientist, though.
