    Re-crowning a muzzle

    The problem is that to ensure compliance with his insurance a gunsmith should send it for proofing - the Proof House would verify this (but then they would) For a gunsmith to attend to this without going to proof is left to his own risk assessment re his insurance. Most people will hang on to their rifles but in the event of a sale a shortened barrel without re proofing could cause a problem for the RFD if he spots it at the time of purchase. Subtle barrel changes are in reality a very grey area as far as litigation is concerned. It may be worth stating that the visible pitting to the OP's muzzle should not affect accuracy but in reality seeing this pitting is also a sign that the last 1 to 3 inches of the bore may also be corroded and that would be a problem causing poor accuracy

    Re-crowning a muzzle

    I suppose the question is - How does it shoot in this condition? I have seen rim fires worse than this still shoot very well. The above options seem the best plan as, if you were to have the rifle re crowned (shortened) technically it would have to be re proofed and the cost of the work + reproof + transit costs both ways would have to be set against the value of this old rifle.

    In that case I would go along with (as suggested) the Hornady 87gr BTHP #2442 as the bullet is for mainly deer. Virtually all powders have a different burn rate although some makes are similar to other makes. If I had your rifle in front of me using these 87gr bullets, I would be looking to do an OCW test using a uniform COL of 2.710" (SAAMI spec). I would chose Reloader Swiss 60 and make up 6 batches of 3. The first batch of 3 would weigh 42gr, the 2nd batch of 3 would be 42.5gr right up to the 6th batch of 3 weighing 44.5gr. It is essential when testing ammunition that as you work your way up the charge weights you look out for pressure signs - flattened primers are a hint but perhaps more importantly look out for witness marks on the headstamp (where it says 243 Win). As you stated, all rifles are different even the same make have different tolerances. The max psi for the 243win case is 60191. By moving up from 42 gr (45524 psi) to the max I am suggesting of 44.5 gr (56531 psi) you should be within the max - however if you play around with seating depths from the SAAMI spec this can affect the psi figures I have quoted. You will also have to bear in mind that Reloader Swiss 60 powder is a high energy propellant and at the max of 44.5 gr your bullet could well be travelling > 3100 fps. At the end of the day it is not speed that kills but accuracy. You may well find that the best group will be in the middle somewhere of the weights I have given you. If you do find a weight that gives good results, try seating the bullet back 20 thou and forward 20 thou with batches of 4 rounds to see if there is any improvement. Your friend would need to know how the OCW target test works and how to interoperate it and he could look up 'Dan Newbury OCW' who was the originator of this concept. There are also a few offerings on Utube. Attached is an OCW test I did for a chap's 243 plus my final test at 200 yds,

    Tyla - perhaps I should ask what you intend shooting with your 243. If it will be exclusively fox, then I would suggest the 75 gr Hornady V max. If a combination of fox and deer then Riohog's suggestion may well fit the bill. Also, as Riohog has stated the majority of American made powders will no longer be able to be imported into the UK (and EU) from this June. Your reloader friend should consider powders that will be compliant - powders like ReloaderSwiss, Vihtavuori and Alliant Reloder - all three brands are excellent and in the main are as good as if not better than US brands.

    You wont find the recipe as in all probability the powder used by Sako has been specifically formulated for their rounds. In any case you will need to buy Sako bullets so that the BC is the same - do a search and see who sells them. FYI there are plenty of the more popular bullets around within that weight criteria that will shoot as well as the Sako provided your reloader friend has the necessary experience.

    What powders does your friend already have? One of the main criteria in powder and bullet choice is having a ready supply of each. Sometimes you will find that the average gun shop selling bullets may only stock the more popular makes - ie Sierra, Hornady or Nosler.
  7. Hello Ian Yup shows promise. However you mentioned that it is a compressed load at 26gr of Varget - well according to QL assuming the following: The rifle is a European make (Tikka Sako etc) as opposed to USA make (Ruger, Winchester) the barrel is 22" and you are seating at standard COL of 2.260" at the lowest charge of 25.4 the fill ratio is 110% so even that is compressed - at 26 gr the granules are being crushed - broken granules will burn differently - the result 26gr Varget = Fill ratio 112.5% Burn rate only 90.6% Pressure 53197 psi (max if European rifle 62366 psi) 3200 fps As you can see even using a powder dropper very slowly, you may cheat the fill ratio by say 2% - most people (in the know) will only go as far as 106%. As you know the European 'REACH' regulations will no longer permit Varget being imported into the EU with effect from this coming June so unless you have several tubs at your disposal, now may be the time to consider a REACH compliant powder such at Vihtavuori or Alliant Reloader to name just two manufacturers. Just as a guide with one EU compliant powder:- 23.8gr of Alliant Reloader 10x (made in Sweden) = fill ratio 105.6% Burn rate 100% Pressure 61740 3396 Fps Peter

    First attempt - got lucky

    Hi Matt Trust you found yesterday useful - sorry I burnt the soup - window cleaner's fault!!! On your journey with reloading please refer back to me at any time. Hopefully if you are looking for a foxing rig in the future, you wont dismiss the 20 Tac! Peter

    Well done you!! There is nothing on those targets that should worry you. The 6.5 is a very tolerant calibre when it comes to reloading. I assume you will be full lengthening each time? I have just run the info you have provided through Quickload at a guess of a 22" tube and at a weight of 45gr predicts 2704 fps (1948ft lbs) with a case fill of 103.9% (so pour your powder into the case slowly) Please bear in mind that the amount of powder burnt on ignition is predicted at 92.21% and whilst not really an issue, you may find that upon extraction you will occasionally see sooty marks down the walls of the spent cartridge (obturation) - it happens in my 6.5 on occasions. Personally I would not worry about getting up around 2800 fps - its not speed that kills but accuracy. Reloading is all about being consistent with your method of reloading - always be methodical - don't take on too many rounds to reload at one time - 20 at a time is ideal, have a system to do your reloading in the same sequence each time. Below is my crib sheet for reloading process - other may do theirs in a different sequence.

    Agree LS Nothing wrong with that little group and for normal stalking ranges that will put meat on the table. You say you may have pulled one of the shots - perhaps you did but also remember if you cant the rifle on a shot it can have the same affect as pulling a shot - I can be guilty of that at times. Oh finally being pedantic!! A 180 gr into that sized living tree (Spruce?) could cause its demise. Attached a couple of photos of my target holder with hinged back for easy transit - just make sure your back stop is solid - and not a tree

    N130 or N133 .223 loads

    Ian if you are referring to the OCW target above - the rifle was (as stated in middle of target) a 20 Tac and the bullet was seated 223 thou back from the lands. On 24 x mag I think I would wander around the bull too much!!

    N130 or N133 .223 loads

    Hello Ian Thanks for the compliment. Those targets were with rifles bought to me so I cannot remember what magnification I used - I would guess as low as possible. When I shoot with my Tac which has an NXS on, I will shoot at 1/2" targets using no more than X6. Reason being, aiming at a very small target sharpens your concentration. I also shoot with both eyes open!! Regarding load development , I am a disciple of the OCW method with a final tweak on COL. I do have a Magnospeed V3 to chronograph results but must confess use it mainly to provide drop charts. Some of the better benchrest people have amazing groups at 600 yds but still have ES nearly at 20 and SD in double figures. My Tac on 10 shots gave an ES of 7 and an SD of 3 ..............once! Regarding OCW test method, I copy a photo of an OCW target I shot about 4 years ago when I was finding it hard to source my usual 39gr SBK bullets so decided to test 40gr Vmax in case I totally ran out of the 39's, luckily the 39's famine ended so the Vmax recipe sits in my folder.

    LS I give below the estimated drop chart using the Sierra 180 SP using both H414 and N140 - the calculation is based on a scope with 1/4 " clicks. This info comes from my Ballistics AE app. H414 at m/v 2661 fps 100 yds zero 2528 fps 200 drop 3.64" clicks needed 7 fps 2393 300 drop 13.36" clicks 17 fps 2261 400 drop 29.88" clicks 29 fps 2132 N140 at m/v 2556 fps 100 yds zero 2492 fps 200 drop 4.12" clicks 8 needed fps 2292 300 drop 14.86" clicks 19 fps 2162 400 drop 33.04 clicks 32 fps 2098 So you can see that dialing in an extra one or two clicks is hardly life changing for the operator!!
