I floated the barrel of my Parker Hale Sporter. Usually I reinforce the stock recoil lug recess and under the front of the receiver with epoxy but on looking at the Enfield I realized it doesn't really have much a recoil lug like most other rifles. I called a good friend who does a bit of stock work as a sideline for some advice on another rifle. As an aside topic, I asked him what part of theEnfield stock takes the energy of the recoil, he laughed, and said your shoulder. That explains a lot .

On an Enfield, there is an area of the foreend that is critical to proper accuracy and longevity of the wood. The "draws" area, where a portion of the receiver fits tight against the wood, is important. If not fitted properly your rifle will pattern like a shotgun. You can also shatter the wood if the fit is way off.

Funny!!! It is a pretty tame round compared to some of the beasts people hunt with. I even found the No5 I used to own much nicer to shoot than a buddies .270 Remington pump.

The main thing here to remember is that,even with a shortened stock to always follow these instructions. |

Its one of the major differences caused by the 2-piece stock.

Thank you for your concern. This rifle is a sporter and there is already very little barrel contact with the forestock. The contact that exists is not consistent hence the need to reduce it to zero. My other option was to enlarge the barrel channel but I don't care for removing wood if I can avoid it. Here is a picture of the modification. Picture is from another forum that is moderated by a well known US shooter and bullet designer. It originally came from Australia. Those light areas are cork strips. The receiver has very good contact with the wood but I will add some epoxy tape to take up any gaps created by the modification. I do not float barrels on full stocked rifles. The one exception is my K31 which I modified on advice from a knowledgeable member on a Swiss rifles forum. It did make a discernible difference in accuracy. Here is his article. http://swissrifles.com/sr/pierre/accurizing.html I have owned rifles with two piece stocks before, both Enfields and assorted lever action rifles and a few break open ones. I have never really paid much attention to the wood as I do on one piece stocked rifles. This is therefore pretty new to me and I appreciate any and all comments. |

Basically the L-E bedding is a pivot about the main mounting bolt in front of the magazine well. The internal sleeve acts as a stop to the (controlled) crush fit of the wood at that point.
If you see a sectioned action & stock you can see the 2 sets of angled planes that are pushed into contact by the teeter-totter arrangement. The differing angles also form a "V notch" to pull everything together fore & aft. The "perfect bedding is tilted at just the right angle just as the 2 wedges both mate firmly. Barrel contact i a full-stocked one is minimal, just the rear BDC of the breech end & a small BDC one at the forend near the muzzle. Everything else free floats. One of the commonest (& most irritating to remedy) is when you have everything set up with the stock open then, as you tighten the handguards, they push down somewhere messing it all up! But of course it only happens after assembly when you can't see it because its assembled! |

Thanks Shamu. It all is going into the CPU between my ears. I am old so it is an 8088 chip. Preloading the front of a barrel on full stocked rifles is the normal practice. In a perfect world it works but wood is not a stable material so external conditions will cause it to alter that preloading pressure. Also as you shoot the barrel heats up and changes in dimension again changing the amount of pressure. Military stocks were not always chosen for their straight grain and any cabinet maker will tell you that even quality lumber, though kiln dried with care, will twist slightly when exposed to damp conditions. Does this make a difference in shot to shot and day to day accuracy. I really don't know. Removing the preloading on my K31 gave a positive result. My M96 Mauser shoots like a laser without changing the preloading. It is illustrative however that the Swedes free floated M96 actions with new target barrels in the CG63 and CG80 match rifles. I have a CG63 and it can shoot better than I can see through the dioper sights. An interesting experiment would be to shoot an Enfield from a stable shooting rest with identical loads with and without a forestock. The rifle would be supported by the magzine. I wonder if you would actually see a change in accuracy or POI. Gossic, I am studying that information pretty carefully. Thanks for posting. |

The guys over at Enfield found out that without proper bedding done,the rifle had a nasty tendency to spread the shots out horizontally. The results of barrel whip. When it comes to stocking up an Enfield,it's best left to following what has been established when the rifle was built. Even with a sporter stock,you maintain the same bedding procedures.

The second photo illustrates the Center bedding procedure. This is the same stocking up method done at Holland and Holland when they were turning out the sniper rifles. Just an FYI on that one...

I know from personal experience that badly fitted wood can make a huge difference it accuray. Particularly with the No1MkIII because the barrel is thinner than the No4 rifle. My No1 rifle had new old stock replacement wood; let's say it was attached to the rifle! because the word "fitted" would indicate a proper job!
It shot around 12 MOA at first test! About 50% of the error was the poor muzzle wear on the barrel. With a NOS barrel fitted it shot closer to 6 or 7 MOA. investigation should poor contact at the draws; causing the barrel to sit off centre in the fore end. Also some unwanted contact between wood and barrel in the channel. Add to that poor nose cap fit etc. Started from the rear end; adjusted the draws with brass shims to centre the barrel and get a tight fit at the wrist as well. Then corrected the contact at the knox form; ensured good trigger guard fit and trigger function. Then removed the unwanted interrefence in the channel and set up the nose cap. It now shoots 2MOA which is OK for a standard bedding on a No1. the only issue I have is the POI moves vertically when the rifle heats up; when shooting service rifle competitions; depending how long between the two targets (for scoring/patching) it has caused me some issues. I have not had time to extensively test the rifle to work out the exct change and compensate depending on barrel temp and ambient temp etc |

I can confirm what ZED says. I had a No5 with a terribly bedded (I use the term loosely) forend. It was 18" off & made a 20" pattern, I wouldn't call it a group, at 100 yds.
I restocked it as a sporter & now its grouping about 4" and shoots to point of aim. Interestingly I decided to free float all but the first 1.5". The logic being that I could always easily build up or shim the front of the stock if free floating didn't do the job. The same applies with center bedding, fix the regular bedding FIRST, then try the center bedding to gain that last bit of improvement if needed. |

As MacD first pointed out, there is not much of a "recoil lug" for the fore-end. I would think the recoil is taken by the butt stock. Seems like the fore-end goes along for the ride; but is very important for dampening barrel vibration (i.e. accuracy). My No.4 is centre bedded; and relieved at the muzzle. I have not experienced any POI shift as it heats up, even after several stages of rapid fire, then back to slow fire.
For years I always loosened the trigger guard screw after shooting. It didn't change POI after loosening/tightening, but lately I've been leaving it tight. I can tell you that a loose trigger guard screw is quickly realized after a few shots. Not sure if leaving the screw tight will eventually deform the wood and relieve the barrel preload.

Thanks more good info. By "Centre bedded" do you mean the receiver only or do you include the first 1 to 1.5 inches of barrel. As soon as I get some contact marking paste I will be checking stock contact of the stock with barrel and receiver. Free floated barrels "whip" but mine all are as accurate as I can expect and some are very accurate. I hear what you say and my own experience concurs with your observations with the stock screw(s). Of course I am more accustomed to two screws on one piece stocks. There the trick is getting proper adjustment for each screw. |

The shifting POI vertically as it heats up is with my No1MkIII*. I do not have that problem with my No4 rifles; one standard and one fultons regulated (centre bedded). This is probably because the No4 barrel is stronger than the No1. Centre bedding is shown in the diagram posted by Goosic on the right hand page.

Zed, is your Fulton regulated No. 4 more accurate than any of your other LE's? I don't have much to compare it with. My only other LE is a No. 4 7.62 conversion (service weight barrel) that was accurized by Dave Reynolds (RCAF SQN LDR) many years ago, and it shoots just as good as the Fulton regulated .303 with 168 gr. SMK handloads. Yes, the Centre bedding is a barrel bearing support between the aft two milled out pockets of the fore-end just forward of the chamber. |
