Is this right?

[njc110381]

I've just been on the Hodgdon website to see what powder I need for the .243. It turns out Varget works ok and I have that so that's what I'll be using, but I also spotted this...

 

Bullet - 100 GR. SPR BTSP

Powder - IMR Trail Boss

Calibre - .243"

OAL - 2.650"

Start - 8.0

Velocity - 1045

Pressure - 27,300 CUP

Max - 15.3

Velocity - 1603

Pressure - 39,100 CUP

 

I can't be the only one that would really like to try this out?! Ideal for whacking trapped Foxes on the quiet!

Trail boss is usually a shotgun/pistol cartridge powder and is a very large dense particle powder - It is therefore a good choice for subsonic ammo in (.308 etc) size cartridges as it fills the cartridge well and lowers the chance of problems with half filled cases... You only have to use a very small grain ammount to produce subsonic performance - ie 8 grains

 

A friend of mine worked up a load in NZ with 11 grains of trail boss in a 7mm08 using a 150 grain (cast bullet) which was a nice subsonic round. The only issue with using factory bullets is getting them to deform/expand/fragment correctly (as you will not be pushing them at the correct velocity) - Not sure if anyone does a bullet casting die for .243 over here but thats what would be best - a cast lead hollow point bullet with trail boss powder behind it. I also heard of people opening up the standard primer hole to increase primer effect on the powder - but thats something you may wish to look into yourself.

 

 

Not got any reloading gear over hear so cant tell you how to do it - but let us know if you find a good load.

My .22lr with subs has a pretty loopy trajectory, wonder what you would zero a 100grain round in at, is there a need for a subsonic 243.

[Newsportshooter]

There is no such thing as a 'loopy trajectory' bullets go forward and downwards at the same time - maybe a little side to side but that effects everything - they dont go up. 100 grains of mass at sub sonic speed provides a 'not so' healthy amount of energy at short ranges (way more than 40 grains at the same speed obviously) - Although that said a .22 will take out a full size Cow without issue.

As for a need - well lets face it if you have a worked up subsonic round for your centerfire and have experience using it then you can throw away your .22lr and .17HMR and carry one rifle for all (obviously this would be cost permitting - if your reloading you set....)

There was much talk of these on a range the other day ..... most of it was about the bouncing bullets! ricochet-tastic

 

Not tried them myself

Have a look at your trajectory charts, in relation to the scope a bullet does go up and down, the word 'loopy' is one many of me shooting buddies use. .22LR subs at about 8 pence each, 243 bullet at 20pence,then powder, case and primer, I wasnt that good at maths but I dont think I will throw away the .22lr or the hmr.

Blimey... I am paying 4.5p each

 

 

... but it is old stock

My CZ only likes eley subs, best I could get em at £35 for 500.

[malkiserow]

Mine were PMC Moderator... they grouped about 1 inch lower that the Eley at 50 metres but just as tight a group.

 

I like them ..... but they are old stock and I understand they don't make .22Lr subs any longer

Hi what 22 subs are you getting for £2.25 for a box of 50 as that is a very good price 8p each is not far off average ie £4.00 a box of 50. Win subs I pay £3.60 for a box of 50 so I would be very interested in your supply of subs for £2.25 coul you let me know the make please.

 

Must learn to type quicker.

Mavis Beatons touch typing Cd, it will either make you a fast touch typist or kill ya. I was going to right a book but by the time I finished the Cd I needed a rest and gave up, then some women robbed my idea and made a few quid, it was something like ' Larry Plotter'.

I used Mavis Beacon as well It was a huge help. Everyone should use it

It caused a lot of unfamiliar laughter from the washing up department every time I had to start a new letter, bleep, bleep bleep bleep, never learned the number keys though.

the thoughts of shooting a full grown cow with a .22 lr or shooting a trapped fox with a subsonic 100 grn bullet both scare me equally as i simply cant deside if a very angry badly wounded cow bouncing about or that 100grn bullet bouncing about is likely to create the most havock in a mans life

[buchangun]

The ****** who have been poaching deer at night up here will love subs in 243 - me I like a muffled bang at night to let the farmer know I've got another fox and as for deer shooting there's only my trusty sidekick and the mountain to hear it.

Too much potential for skulduggery with subsonic .243 in my paranoid jingoistic opinion

Anyone tried Mavis Beacon Teaches .243 Subsonic Reloading?

[Redgum]

I did have ago but the cd snapped going through the full resizing die, should just have neck sized it.

I had exactly the same problem with mine. Must be a design fault or not enough lube.

I bought a tub of Trail Boss a few weeks back to experiment with. Where the usual Hodgdon tubs hold a pound of powder. Trail Boss is only comes with 9oz as it is much lower density than most regular powders, it nearly fills the tub though. It looks like miniature doughnuts! I loaded up some spare Hornady sxsp 55gr bullets and shot some targets. It was remarkably quiet even without a moderator, but getting subsonic loads I think would prove quite difficult in smaller cases. Maybe with a .308 and heavy bullets it would be ok but .243 and below still results in supersonic velocities.
