I tried some Eley match through my Rim-X midweek whilst visiting a tunnel range. Top group is 10 at 100m, middle is 10 at 50m and bottom was the last 5 shots in the mag at 50m. It shows some promise, though I expect it would improve with the tuner. I did notice the lighter coloured lead bullets makes it easy to watch them in flight.

What I find is a little disappointing is that, what is normally thought of as a fairly respectable match quality grade of ammunition, there is a spread of 30 fps.. That's around  3%.
If your centrefire match grade ammunition had the same 3% spread we are looking at around 90fps, not something I would be particularly pleased with.

What rifle..?

The clue is in the pictures. 

Anschutz Match 54.

Let's drag this post back to the top..
I had a chance to test 5 different types of ammo yesterday at 50 yards. These were shot off the wobbly tables on Melville 50 yd range at Bisley, a chilly 3c and fairly light winds.

I can't explain the vertical spread of the Centre-x ammunition, it usually performs quite well for me.
Best pair of groups were the Midas + with both under .5 moa (But the most expensive)
The SK-Auto, the first time I've tried it in my M54 shot surprisingly well for cheap ammo.

The black patch spots are 2cm (.79")

My example for a Savage Model 12  FTR in .308

   

From a distance you'd think it was a plumber's 15mm pipe slice 😃, but it Works a treat. 

 

Good job..👍

I shoot .22lr ( and air) benchrest, mostly 25 yds and mostly NSRA rules (Flat front rest, shot off the shoulder so no rear bag). I shoot in a Kent local league weekly and inter county comps. I also shoot with the Long range rimfire club out to 400 yds at Bisley.

I use an Anschutz M54 in the TR class, a Sako P94S Finnfire for sporter and a Steyr LG100 for air.
The NSRA do a postal 25yd benchrest comp and there is also Eley postal benchrest comp.
Quite pleased with this seasons average of 100.45 over 10 rounds.

Just for information - I make one or two bolt decockers - Mauser 98, Remington 700, Sako P94s and a Remington 700 decocker and takedown tool.

On the Mauser you need to push up the little spring loaded plunger before turning the bolt body to cock/uncock it.
Here's the Mauser 98 tool but not sure if it will fit your bolt.

And the Remington 700 decocker/takedown tool 

Not at the moment David -  I can't see any problem with making one but I would need an actual bolt for a few days, it's sort of thing you can't make by measurements when 3D printing. It takes several tries and a bit of tweaking every time to get it right. The plastic stuff shrinks a bit as it cools and not always in the same direction but once you have the machine dialed in it's right every time. The Mauser one took ten prototypes before I was happy - actual printing takes around 3 hours each.

I've also just made on for the Remington 700 bolts:

To drill the size of the cavity that the Paco tools produce would significantly reduce the weight of the bullet - would that be a + or - point?

Got you - I thought the Paco tool didn't use a shell holder - with the head of the cartridge just resting on a flat surface, then pushed out after forming the bullet, a bit like a Wilson hand die.

Ahhh - Am I barking up the wrong tree? Did you mean a .22lr shellholder to fit a press for reloading .22lr?

What sort of thing are you thinking of?
I'm a hobby "maker". I can design, 3D print and machine an assortment of small parts.

These are 5 and 10 round .22lr "Quick loader" with embedded magnets to attach to BSA Martini (or similar) target rifles.  3D printed or hand machined from aluminium.

I've just designed and printed this little gizmo to de-cock a M98 bolt - works very well.

I’ve got one on my newly acquired MkIII - it’s excellent!

Thank you - I'm pleased it fits and works well on your International Mk 111. Are you planning to use it for benchrest or long range rimfire competition shooting?

Initial thoughts:  Why only check ± 4moa range?  I would have optically centred, bore-sighted and then check out the full range of elevation ±27.5 moa.  Then from a bore sighted zero find out what my shot zero is to confirm the 'starting position' for elevation - ie identify how much up elevation adjustment you have given 20moa rail.  If all looks good then shoot again at 300/600

Agree - From your 100 yds zero I would have checked full up/down, left/right to see just what you have available. I think point of impact at 100 yds should be about 16 inches above you aiming mark for a 600 yd zero.

What range have you got locally Simon? Even with a 25 yard range you should be able to test your scope and you could make up a "tall" target similar to the old Bisley zero targets. Using your ammo data and your ballistic app you should be able to check proper function of the scope and zero in for 600 yards.

I’d love to be able to shoot R50 which it loves but it’s supersonic and all my local ranges only allow for moderated subs 

 

I think you'll find R50 is not supersonic unless in quite cold conditions of around 0c - Published data states 1082fps (330m). Chrony figures through my Annie M54 showed around 1070 fps. Transonic speed at 68f (depending other odds and ends) is 1,125fps.
 

I use a Contessa 20moa rail on my Match 54. (wish I had gone for the 30moa now). Good quality and fit

Anyone interested in these type of bits, they are explained well here. Usual practice now would be to start with a silver steel rod and, hammer one end to spread the diameter then rough file to shape, temper and finish. Used for clock plate pivots and often made by eye to fit rather than any particular size.

I think these are handmade spade bits - as used with an Archimedes type hand drill in clockmaking. 

Great mod - well done.

Gave my old Annie a bit of an airing today - three different types of ammo, all 5 shot groups, all 50 yds off bench at Bisley. (Shot on 25yd prone targets)

Let me know how you get on. I’m picking up another .223 and want cheap brass because I’m good at loosing it in the field or truck! 
 

it never gets loaded more than a couple of times in reality when it’s one of my hunting rifles. 

I loaded up a batch of PPU .223 brass and shot it on Saturday at Bisley in my old CZ 527. No problem at all with it. Only 109 yds, wet and breezy but managed 10/10 into less than an inch.

How is this democratic - The guns were licensed. What's he calling "armour piercing" ammunition? A jacketed bullet?

If anyone thinks this won't eventually effect them has not been shooting long enough to remember the freedoms we once held.

The smallest is 1/2 the size of the largest. Any idea why?

 

Because it's a .22lr - and that really irks me.

Surly precision shooting is just that regardless of rifle choice ,no powder prejudice 🙂

I agree - Run a string from a modern regulated airgun through chronograph  and anything outside single digit ES is poor - If only rimfire ammunition could do the same. You would think that with well over a hundred years of development, billions of rounds, hundreds of manufacturers each with R&D departments they would have nail it by now. Even paying for top grade premium ammunition the velocities are far from consistent and vary from lot to lot. I can't help thinking that if primed cases were readily available for home reloading the manufacturers would need to up their game.
Maybe an accurately measured slug of solid propellent would give more consistency.
