Loading for ruger#1 303 British

Good post Biged, thanks. Where did you get that case gauge?

I'm in the U.S. and ordered it from Midwayusa.com

L.E. Wilson Case Length Headspace Gage 303 British

"BUT" rather than buy one gauge for each caliber, I would buy the Hornady Lock-N-Load Headspace Gage 5 Bushing Set with Comparator the only thing else you would need to go with this set is a vernier caliper.

In the end if you have multiple rifles you will spend less money.

I've always had a sweet spot for the 303, and was tempted to get a #1. Still might, hence the reading this thread.

The other day I was skimming "Hatcher" and it says that the groove diameter on a P17 (30-06) was 0.310, and when this thread indicated that Ruger made the groove diameter 0.314, it sounded like that may be normal, so I looked up the SAAMI spec on the 303 and sure enough, groove diameter is listed as 0.314.



I don't have a lot of experience with reloading the 303, but the powder recommended to me by the old timers at work was 3031, and that always worked for me.

Slug the bore, I have 2 friends with this No1A in 303 British and both of these bores measure .314. I cancelled my order as I did not think it would shoot. My friends report that theirs do not shoot. One of them contacted the Ruger plant and they confirmed that the bores are 314. Why Ruger did that I do not know. I had a 1A in 7mm Mauser which I never should have sold, it was very accurate and I wish I had never sold it.
Slug your bores, maybe Ruger went to 311, if so good for you
 
Check out the articles at < www.303British.com > The original specification for the .303British is .303" for the bore, if you add the depth of the rifling grooves (.005 - .007 x 2) to .303 you get 0.314 to 0.317 as production tolerances. Keeping in mind that no one air gaged barrels in 1887, or 1917 for that matter, and that the Brits were designing a battle rifle made to function in the mud and heat of any battle field around the world, it should not be a surprise that the American ammunition companies got the specs wrong.
 
best .303 recipe I've come across is 40 grains of IMR4895 powder with Hornady 174gr FMJ bullets, seems to work great with several different Lee Enfield No4Mk1's & Ross Rifles
 
A question or 2 for all you fellow Ruger No 1 303 Brit owners and reloaders. Are you full length re-sizing your cases?
I have been loading for a LE No4Mk2 and have been neck sizing the cases and keeping the brass specific to that rifle. I have had case head separations on the very first reloading of cases that were fired from my LE but were full length re-sized. Switching to neck sizing has solved this issue.

I have tried the same neck sizing only process with my Ruger No1 and find that I am having difficulty chambering re-loaded rounds. They require a very hard push to chamber and they often need the extra force of the block rising up to fully push the case into the chamber.
They are not over length. They are new reloads of 174 gr Hornady's on RP cases fired only once from this same rifle. I just re-loaded the brass for the second time last week and because of the problem I was having with chambering the neck sized cases, I decided to FL resize this time.
Full length re-sized cases drop right in the chamber just like factory ammo.
I am curious to know if anyone is having this issue with the Ruger No1
 
I just shot a 4 point elk with a paper patched cast bullet out of the #1 in 303.
I will post pics and details later, but for now, I will only say that I was very pleased with the performance of the load.

Well done Boolitcaster. I would appreciate knowing more about the specifics of the load you used. I wouldn't mind trying some cast bullets in my #1 and in my Ross sporter. I may have to change my CGN alias to 303junkie.
 
Thank you, I am still waiting on some photos which are on another fellow's camera.

The elk spotted me at 25 yards and by the time it was at 75 yards, I had a chance to take a quartering shot at it. After I shot, it slowed to a walk. This gave me time to reload my Ruger #1 and put another shot through it's ribs at 100 yards when it turned side on to me.
It collapsed seconds later.

The bullet was a Lee .309" 170 grain bullet, cast out of range scrap and hardness tested at a BHN of 12. It was sized down to .304" and then paper patched with green bar printer paper and lubed with JPW and then sized again to .314". It was pushed by 39 grains of IMR 4350 and the airspace filled with enough dacron to compress slightly.

My first bullet had entered at the rear of the rib cage, perforating the liver and then passing through the lungs. Due to my being down slope from the elk, the bullet then struck three vertebrae and the major blood vessel that runs parallel to the spine. Then glancing off the spine, the bullet continued through the right shoulder and came to rest under the hide half way up the neck. I recovered the bullet during the skinning.

My second bullet passed through the lung cavity smashing an inch out of both the incoming and outgoing ribs.
I am sure the elk would have dropped in seconds whether or not I had taken the second shot.

The recovered bullet weighs 135 grains and shows evidence of travelling sideways for some time, probably after striking the spine.

This would be considered a very mild load with recoil similar to a 30-30. I had been working on some 210 grain bullet loads, but I could not get any decent accuracy in the limited time I had. Departure time arrived and I decided to take a load I had developed last year for shooting Island Blacktails.

The bullet on the right was shot into a pine block to test expansion.
The next bullet to the left was the one recovered from the elk.

This was an out of province hunt.

I was surprised with the calibre, very nice to shoot an the trigger on the rifle was very good, one of the nicest on any of my rifles.. not sure if it had been touched up, rifle was ony fired around 20 times before trade.
The first 3, Note first 2 were LOW off box

So today I was shooting some Remington Corelokt 180gr at a target, first shot I aimed at a white square 4x4 inch, it hit the tree spot on an blew the target off, So next shot I aimed at the bullet hole and it shot in the exact same area(1st hole blew 2 inch of bark off tree), Im more than happy with the ruger accuracy with both factory rounds ive tried.

The issue I had with the 2nd shot was a stiff lever when I ejected the spent case, in addition to this I also noted some residue on the primer where the firing pin had struck, white-ish stuff.... not sure where this come from?
whats your thoughts? I havnt a photo on hand an I wiped some of the stuff off but maybe someone can relate to what happened?

cheers

Man! I had to look at your location, I'm still stuck in the ice at our range! LOL! The white sh!t can't be snow in your area, so my guess is maybe residual blueing salts from the rifle?... I'm not sure it would cause a stiff lever though? Spent brass ok? What's the chamber look like?
 
Any advice on loading a 303 No.1 with IM4064 and 174gr bullets? The Hodgdon max for a 175gr bullet/IMR4064 in a 308 Winchester is 45.6gr, however, it is listed as a compressed load. In a 303 case with 174gr bullet and 46gr IMR4064 at 2.98" there's lots of room but I don't know if it's safe to exceed 45/46gr (I've been using 308 Winchester data as a guide for loading my No.1 with RL15, H4350 and BL-C2 with good results).
Thanks!
 
Would it be correct to think that, I realised I had verniers here so I stuck it in the end of my Ruger 1 barrel, an I couldn't get a higher number than .3095 ???

I was expecting different.


Also has anyone tried 308 bullets in theirs lol?
