Thread: .303 load data

Anyone have a load for 150gr using either win760 or win748

I tried using the search but it doesn't come up with anything

Toby

I can look up some loads in my Manuals and post some pics if this helps.

Cheers
Pete

That would be very helpful Thanks.

I can't find any load in my data using that powder to projectile weight

This is what I have.

Lee 2nd edition, 150gr Projectiles

W748 start 45.4grs max 45.4grs 2564fps

Speer Number13 150gr projectiles

W760 Start 44.0grs 2319fps max 48.0grs 2575fps (recommends to use magnum primer).

Nick Harvey 2nd edition 150gr Projectile

W760 start 46.0grs 2370fps max 50.0grs 2600fps

Lyman 48th edition 150gr Projectile

W748 start 39.0grs 2149fps max 43.5grs 2523fps

Hope that helps.

Kiwi Sapper shoots the 303 a lot and may have some better information.

What action are you loading for?

Cheers

Awesome that'll do me fine.

lee enfeild.

Lucky I asked here I went on google and came up with 50gr 760 but it filled into the neck and didnt feel right in my gut.

Lucky alright.

Although Nick Harvey lists 50grs of w760 as the maximum.

But it's never a good idea to work up a reload starting at the maximum.

I believe the Lee Enfield action is rated at 45,000cup and is possibly the weaker of the actions used for 303 British.
But someone who knows more about this might be able to enlighten us all.

Make sure you have the headspace checked too.

Let us know how you get on.

I loaded up some at 44gr. Just want bullets to shoot. Gun was fine last time it was used except for the aluminum butt plate. Will change that one day

Fark these .303 projectiles are expensive.

303 150grn SST Projectiles | Trade Me

$89.95 at Serious shooters
$77.00 at Reloaders Suppliers

Same projectiles in .308 are $65 retail at Action Outdoors and Marine in Napier.

I have a box of seirra pro hunters cant remember how much they were. 60 something for 100

If you're after cheap projectiles for .303, be sure to try the hornady 174gr RN. They're a genuine .312 projectile, and work a lot better in worn barrels. They aren't much good beyond about 200m but are good within that range.

For powder, most of the service rifle guys run 2206H or 2208 with good success. Just a thought if you aren't too committed to using 748 or 760.

What projectile do service rifle guys typically use? an SMK or equivalent, or is there just as good, cheaper options out there?
My understanding is the Lee Enfield is typicaly a 2-3moa rifle, is this accurate enough for service rifle?

that sounds seriously compressed.

ADI 2208 is pretty good.

Yeah that's why I stopped and thought it was bad.

I remember loading a few ages ago and the powder wasn't in the neck but I lost the load for it. Won't lose it this time, I put it on those stickers that come with Sierra projectiles and put it into my folder

I use Barnaul FMJs, 174gr flat base, 32cents each. I use them for target shooting to 600m on my no4 mk2s. A standard no4 mk2 should do 1 3/4MOA at 100yds, good accuriased ones get to 1 inch MOA. No4 mk1s about 2inch MOA, though the T's were better. I suspect its a quality control thing from war time production and how good a barrel you got/get ie the wartime ones were rush jobs and sometimes not very good. If you are getting worse there is something wrong, often bedding or bore wear.

Service rifle has classes so its say 10 x 303s shooting against each other and not 303s v AR15s. Of course at 500yds+ the .223 AR15 is no where, 100m and they are impossible to beat.

ADI Powders Handloaders' Guide

according to that winchester748 is roughly ADI2206H and w760 is ADI2209. I use 2208. I dont know what 303 you have but a P14 is a bit stronger than a no4 lee enfield, however no4s were fitted wth 308w barrels so would have 45~47gr of 2208!

I'd start at the min, your brass will last longer and its safer. Headspace should be tight-ish as well.

I use Fed210 primers, 1943 brass though I just got some new Privy brass to try this weekend. Also some once fired winchester Ive reloaded to try with sierra matchkings. I have some S&B brass but that needed de-crimping and ppl tell me it doesnt last.
