Bayonet affect accuracy?

[SwedeSteve]

jmp- I went back and reread this thread. The one thing I failed to ask, was if you've ever sighted in at a closer range?

[jmp8927]

I rough sighted at 50 with Wolf before. I wasn't trying to get extremely precise as my intentions were to get it accurate enough to hit paper at a longer range. I may end up sighting it for 50 and leaving it there for now.

[SwedeSteve]

jmp- NOPE! Sight in at 20 meters! That is what the Russians did. You will be a couple inches high at 100m, and close to dead on at 200m. All things being equal... Unless you can reload, and work up a recipe that your specific rifle digests well, I would sight in with the cheapest ammo available, if you plan to just "blast". If you plan to hunt, then this advice goes out the window! I think you have a fine SKS, and maybe jumped the gun a bit, aka went too long from the get go! I only have 10 years experience with the SKS, so maybe someone who has been there and done it before me may want to chime in!

[jmp8927]

My sight tech instructions do say to sight in at 20 yards to be on at 200. Thing there is, am I going to be shooting 200 yards? I think that's a tad bit far for a SKS with open sights. However, it is worth a try. And I don't see me doing anything but maybe maybe hunting deer under 100 yards until I get a good scope for my .30-06. Hopefully I'll have it before August and then I wouldn't need my SKS for hunting. At any rate, the 20 yards might be worth a try. I don't mind playing with my little baby Is it odd to become so attached? lol

I checked out the ballistics table for a 7.62x39 125 grain soft point at 2,365 fps. On the table, this load zeros at 20 yards (on the rise) and 200 yards (on the downhill side).

If you sight in at 20 yards, you will be within 5.5 inches MAX out to 250 yards. that is to say, if you are shooting a box at least 5.5" square you need not worry about hold over or under until after 250 yards.

On line ballistics calculators are wonderous inventions once you can finally undersatand them.

My current favorite is here:

AmmoGuide Ballistic Calculator

mitch- Thanks for the link! I lost it! My comp is a mess. I have stuff tucked away everywhere! jmp- Shoot at 20m, make your adjustments, and if you can kill Ivan at 100-200, you have maxed out the SKS! Next, a Mosin M91/30 at 300m!

When ya get it fixd let me know

You and I mitch will be too old to type by that time! LOL!

I have A DPMS AP4 .308 carbine with a quick detachable leupold Mk4 2.5x8x36mm. at 300 yards my groups are about 2.5 Inches I use a ballistics calculator as well. and to day I plan on doing some 600 yard work on a man sized target Just to see how it goes.... I ran some .223 wolf through a chrony and I didnt believe it but from a 10 shot string it had a standard deviation of about 13 feet per second. If your the type to use consistant speed to judge how your ammo will perform there you go. I would reccomend Load development for any rifle (this requires reloading) I prefer the Incremental Load Development Method Randolph Constantine did a write up on this and I would reccomend googling for it. I have found for me that method work's wanders for Barrel Harmonics. Here in Fairbanks Alaska we deal with massive temrature fluctuations Ive seen tempratures drom from 20 degrees to - 30 below over night, I work all summer..... and shoot in the winter and out of curiosity I chronograph my loads in all differant tempratures from 80 above to -30 below and You'd be amazed at what havoc temprature wrecks on ammo.. so make sure you acclimate your ammo. If I take warm ammo out of a 70 degree truck and and immediatley start shooting it over my chrony at negative temprature the results are unpredictabile at best..... sometimes standard deviations are 60 FPS the same ammo acclimated shoots an SD of about 10. Ive never had any trouble with my quick release scope walking and i find it hard to belive any rifle will shoot 5 MOA but I learn somthing new everday. I never expected any AR style rifle to shoot Sub MOA and i was playing with mine from boredom alone. so if you ever get a few bills and want a tack driver battle type rifle I reccomend researching DPMS . I Hope I've helpd

A collapsable or folding stock wiggles a bit from the moment you pull the trigger. I've never seen a collapsable stock of any kind on a target or sniper rifle. They have their uses but accuracy is not one.

Now, you will never be able to say that again...

[jmp8927]

To me it doesn't make sense that a folding or telescoping make much if an difference in the accuracy of the rifle. It's arguable that it makes the shooter less accurate, but I don't think that applies to experienced shooters who don't jerk the trigger. Now were it a fully automatic rifle, it would make the shooter a lot less accurate as it allows the rifle to move after it fired and thus the rifle is farther off target for the 2nd shot. But for single shots, I'd have to say folding/telescoping doesn't make a difference.

Very nice pic SS!

OK, but this is the exception, not the rule. Nearly all target or sniper rifles have rigid stocks.

The rifle starts moving around the instant that you start pulling the trigger, experienced or not. That is why people bed actions. It keeps that little bit of wiggle that occurs when there is a less than perfect action to stock fit.

You can bet that a folding stock will make the firearm a little less accurate. It may not matter that much for an SKS but when you start sticking on a bunch of after market stuff all over the gun then expect accuracy to go down, even for a marginally inaccurate rifle like the SKS.

Mitch,

I am willing to concede that the stock on that weapon is not a $59 Choate folder. I understand your point, but nearly all US sniper rifles have a telescoping butt. It is for adjusting LOP.

Here is the Army's M24...


If done PROPERLY a telescoping buttstock should have zero effect on accuracy.

That stock is a set and forget. It is not intended to fold, so it's made rigid. There is no hinge or release to collapse. One this stock, you set the length of pull, then tighten down the set screws and it's left alone, solid. Much different from a stock that is maded to fold/unfold as a routine.

The only Time I can imagine that making any huge differance is beyond the 500 Yard mark. (That is assuming the folding stock does not noticeably wiggle. ) I have a telescoping stock on My AP4 and at 600 yards im shooting around 5 3/4 MOA. for this type of setup up im estatic i never bought the rifle to shoot beyond the 500 yard mark and Im completely out of any real magnification at that distance because my scope is a MRT 8x. My point being on the average rifle and in the hands of an average rifleman this will not be a issue. the telesoping stock should make little or no differance at all. out past the 500 yard mark you will of course want to eliminate all error and a wiggly stock is definanly a source of error. Ive allways wonderd why people spend thousand of dollars bedding actions and all that voodo.... when a average stock rifle (there are lemons) will shoot 600 yard plus. The average Joe is not capapble of shooting that far.

P.s

I would like to note the 5 and 3/4 MOA noted above was and average of 10 shots as measured from point of Aim... my gouping extreme would grow to just shy of 12 inches if i measured the extreme spread. however with this type of rifle and low power scope Im still extatic. anything bigger then a jack rabbit is pretty much toast and thats good enough for me.
