DLH Posted January 24, 2016 Report Share Posted January 24, 2016 Has anyone got any experience with this cartridge. I am thinking about getting a custom rifle built to replace my .223. Can anyone shed any light on case forming? Barrel life? Best bullets for a 1/7.7? Anything! Cheers all Link to comment Share on other sites More sharing options...
Akeld Posted January 24, 2016 Report Share Posted January 24, 2016 Not personal experience, but a good friend has one. He was told to expect 900 rounds of accurate barrel life, as its used purely as a fox rifle he was happy with that. The guy who built it also does his loading and measures the chamber and inspects the throat every 100 rounds for signs of wear. It was originally set up for 75gr Amax but now he's using 73gr berger, he's never had a more accurate rifle Link to comment Share on other sites More sharing options...
Vermincinerator Posted January 24, 2016 Report Share Posted January 24, 2016 A 22-243 Middlestead wont do anything a 22-250 Ackley cant do, barrel life will be better then the Middlestead. Just as good and i bit different would be the 22-6.5x47 Lapua or .22 Satan as i believe its called which would benefit from the small primer pocket and PPC sized flash hole of the parent case. Ian.

hunter686 Posted January 24, 2016 Report Share Posted January 24, 2016 22br Is well worth a look at! 22-250/Ai speeds, better barrel life, good brass. The definition of a custom rifle caliber. Pretty sure 6mmbr.com did a write up and comparison. Link to comment Share on other sites More sharing options...

Davy Posted January 25, 2016 Report Share Posted January 25, 2016 My wife still shoots her 22-6,5x47 from time to time. The rifle is a Savage single shot with a 29" heavy barrel. She uses 80 grain SMK's although these days they are pointed and the rifle is mostly used for 1000-1200 yards. Case forming is easy enough and I will have a copy of her case forming instructions somewhere if anyone is interested. One possible advantage is the small primer and the cartridge will move the 80 grain SMK just on the 3280feet/1000m per second mark, no doubt it will go faster however this is her chosen load. Recoil feels to be slightly up on a 250 and barrel life is good with hers at just over 900 rounds and still holding a true .2 MOA or better with very little effort.

pork chop Posted January 25, 2016 Report Share Posted January 25, 2016 i had a 22 Br that would touch 4k with a 50 gr vmax but settled on a 53 gr vmax at 3650 ish got about 2000 rounds through it Link to comment Share on other sites More sharing options...
gbal Posted January 25, 2016 Report Share Posted January 25, 2016 DLH: the Middlestead has real charisma. One consideration for all the hot 22s is that the standard 243w will podium with any,out to 400yards(where velocity is king) eg 55g @ 3910fps (Win B silver tip);3850 (Nosler Bal Tip)-factory of course. Beyond 400,BC takes over,and so therefore do the 6mms (243 with 80g @3350 -rem/win factory). Bullet choice is currently limited for some small quarry. Everything mentioned is an excellent varmint cartridge to 400; but to 1000 the 115 DTAC fast twist 243 will beat the few that can even think of that range,but that's another rifle really (unless the fast twist 243 will shoot the 55/58 g bullets?) Middlestead remains a real 400yard contender,though. gbal Link to comment Share on other sites More sharing options...

Vermincinerator Posted January 25, 2016 Report Share Posted January 25, 2016 Im running 55grn Blitzkings out of my 22BR at 3580fps which is my pet load, tried 40 grn Blitzkings and had them zipping along at 3940fps but they did not quite have the accuracy of the 55s plus the added knock down power of the 55 is a bonus.

gbal Posted January 30, 2016 Report Share Posted January 30, 2016 Buy a swift and save case forming. Maybe- back in the day,I was put off the Swift by being advised to buy a lot of brass,if I could "stretch" to it......this was not quite offset by the claims of a canny old keeper who maintained the Swift was not as flat (as the 22/250) "because the Swift is only flat to 300 yards,then it rises up a bit". :-) gbal Link to comment Share on other sites More sharing options...
OSOK Posted February 21, 2016 Report Share Posted February 21, 2016 Hi guys , I have a 22-243 Middlestead but use it for longer range with 90g er's , I also use the 220 swift with 53g er's as a fox round . I fire formed my Middlestead cases (300) in an old barrel at 100 per night in a local tunnel range which I'll never ever do again . A 22-243 case that's not fire formed will still work well as a 220 Russian does before it turns into a PPC . I wouldn't use the Middlestead as a fox calibre as it would have a approx 100 ft/sec advantage over my swift which is nothing out to 300 yards . My swift is pushing the 53g at 4,030 ft/sec and drops 5.25 inches at 300 yards and a 100 ft/sec advantage wouldn't loose the 1/4 inch . Using a 7.7 twist would be based upon heavy bullets rather than the usual 40-55g range of fox bullets . OSOK Link to comment Share on other sites More sharing options...
gbal Posted February 21, 2016 Report Share Posted February 21, 2016 OSOK,interesting. Though your Swift load must be rather hot,I hope any wannabe hotshots take on board your findings that 100fps makes no discerible difference at 300y,which is pretty much so for most such cartridges. Have you found the 1in 7.7 Middlestead with 90g has any advantages over the 'straight' 243 at distance-the 243 will have better BC,similar velocity with 87g,and BC tends to give the edge at 350+? Just curious,as my yen for the Middlestead waned when light 243 bullets took care of the shorter ranges,but there isn't a really good 243 varmint bullet around 90 g....yet. gbal Link to comment Share on other sites More sharing options...
Montey Posted February 21, 2016 Report Share Posted February 21, 2016 I use 95g Noslers in my RPA 243 the Noslers version of V Max and they work realy well on mr fox. I'm using this as my 22-250 is being re done with a longer barrel with the mk 2 Drone good out to 300yards. Link to comment Share on other sites More sharing options...
OSOK Posted February 21, 2016 Report Share Posted February 21, 2016 My Middlestead was built to shoot 80's but buy chance i tried the 90's and they worked very well . As for anyone shooting and looking for an advantage over a Swift or 22-250's etc then i'd say don't bother but to anyone who's just got an itch for a Middlestead then scratch it and go for it . Mine is usually shot at 500 plus and has similar ballistics to my 6 x 284 shooting 115's at 3,275 ft/sec , That from a 22 which has had kills out to 1,220 yards and has been repeatable at 1,800 yards + on suitable surfaces is why i rate it so much . My Swift load as been the same over the years and as the barrel has aged the velocity has increased from Circa 3,912 ft to 4,030 ft . I don't see or feel any pressure signs this maybe down to my barrel . I'm unsure how you can call the load ' rather hot ' without knowing if it's out of a 22 inch or 32 inch barrel ( mine is a 27 inch ) Going back to the original point , Anyone who shoots a 220 Swift or 22-250 and wants to just shoot foxes then stick to what you have unless the itch is real bad BUT there would be nothing stopping you putting a 7 , 7.7 or 1 in 8 twist on and using 75's or 80's on anything out to and well past 1,000 yards without changing calibre . I must say that whilst my rifle shoots the 90's in a 7.7 twist well please don't assume they all will as mine mightbe the exception to the rule which is backed up by barrel makers .

gbal Posted February 22, 2016 Report Share Posted February 22, 2016 OSOK-accepted no-one knows actual pressures etc,nor the exact individual barrel effect of 3 inches length. CIP 24 inch barrel 54000cup loads: Hornady 50Vmax @ 3850 Nosler 50 Bal tip @ 3900 Fed 52SMK @ 3830 So 3912 increasing to 4030 with use with 53g from a 27 barrel is only mildly warm probably,but it is an extrapolation,agreed,as must be barrel length increase effect.But fair enough. For the guidance of any newbies, searching for the holy grail death ray,would it be fair to add that there have been some misses at 1220 yards,( estimated drop 560 inches,well over half that wind drift in a 5mph wind);and clarify what 'repeatable at 1800y+' means? misses,yes but hits on what? gbal Link to comment Share on other sites More sharing options...

OSOK Posted February 22, 2016 Report Share Posted February 22, 2016 gbal , The books that your quoting from are a guide to make people aware of when pressure can be an issue according to their test barrel . I'm now on my second barrels in both Middlestead & Swift so any data i give is ' Real World ' but i'm pleased to have gone from rather hot to mildly warm I have two 7/270 wsm barrels here that are both chambered with the same reamer by the same guy and using the same match load in both i'm seeing 110 ft/sec difference , There are too many variable's with barrels . The only reason for joining this thread was to give any help i could to anyone wanting a Middlestead as i feel i know a little about the pros & cons of it . Most Corvid's have approx a 2.5 inch diameter kill zone which at 1000 yards plus is very small so yes i'm missing more than i'd like to admit but then if it were easy we wouldn't love it so much . One piece of advice i can give whatever calibre you use is Don't do what i did and chase the distance shot as i found that the 500 -700 yard area seemed easy on gentle days with only strong gusts and certain fish tails catching you out . You then don't bother and wait for the distance shot which gets harder to find let alone hit ! I went from a high hit percentage to an awful one during a 12 month period until i realised it was so silly and whilst i still crave the distance it's not what i set out for anymore . Repeatable means that at 1840 yards the rounds were not tumbling even though they were subsonic , striking on shale which at that range was the only way of seeing the 90g strike . From memory my ES gave a vertical dispersion of approx 16 inches at that range so with wind etc i knew the shots were repeating within that horizontal band .

gbal Posted February 23, 2016 Report Share Posted February 23, 2016 Thanks,OSOK.I agree with Ballistic Hamster that you have made clear what you meant,which was what I 'wanted';and your general position on long range. I can well believe misses as well as some hits;and WEZ analyses of such things tends to suggest that halving moa precision,and most other rifle and load tuning isn't the big issue-which remains,as ever,errors in wind reading-which can only increase with distance.Vertical is only subject to the steady laws of gravity physics,and consisteny in ammo should give your kind of consistency of splash. Impressive stuff,nonetheless,and goes someway to dispel that old timer's belief that the Swift isn't flat shooting,because it starts to rise up after 500yards.... :-) gbal Link to comment Share on other sites More sharing options...
Ballistic Hamster Posted February 23, 2016 Report Share Posted February 23, 2016 Need a good reference book in beliefs , seems better than real world data have to stay in more and reference it to determine how far do you want to flat shoot And OSOK might follow on this Link to comment Share on other sites More sharing options...
