Shooting Lee 185 grn lead bullets. A friend of mine gave me a quantity of 4350 IMR powder. I wanted to shoot it in my Enfield. Not wanting to risk one of my better guns, I chose a No 4 Mk1 that had seen heavy use. I spent several days cleaning this rifle and had finally got past the gunk down to the rust and pitting in the barrel. I started off with a load of 43.3 grns. I was shooting a gas checked lead bullet cast in a Lee 312 mold. The bullet weighed 185 grns, and was cast out of wheel weights. I had slugged the barrel and it miked out at .313. I machined out a .313 lubricating and sizing die and lubricated and sized 50 bullets. I set up a steady rest and shot 20 rounds. The targets were a disappointment. The barrel was thoroughly fouled and the grooves were full of lead.

I cleaned the rifle. I took a wax candle one inch in diameter and six inches long. I melted it in a soup can and stirred in one heaping teaspoon of petroleum jelly. I laid out a strip of aluminum foil in the bottom of a regular dinner plate and poured the mixture out and let it cool. Once it had cooled, I separated the thin wax sheet from the aluminum foil. The sheet of wax was about a tenth of an inch thick. I neck sized and primed my cases. I loaded 33 grn of IMR 4350. I took the charged case and pushed the neck through the wax sheet inserting a wax wad. I then seated the bullet and crimped the case using a Lyman 303 die. I loaded ten rounds of 4350 using the wax wad and ten rounds of 45 grns of Pyrodex using the wax wads.

The groups were very good. The Pyrodex group at 25 yards was spectacular. The rifle showed very little fowling and no leading.

43gr of 4350 is a decent charge under a 185gr bullet and you will be breaking 2000fps so your bullets will need to be hardish and a very good fit to shoot well. Slug you throat and make a sizing die to suit that. My bet is the throat will be much larger than .313 as both of my .303's are at least .314 and they have MINT post war barrels.

Not sure about your lube. I would advise use of a reputable bullet lube as a base line to begin with.

The reason your Pyrodex load is shooting well is the pressures will be significantly less than those from the 4350 load.

Keep chugging away. These old war horses can shoot VERY well if you put the time in.

If your bore is .313 I would be sizing those bullets at least .314. Sounds to me you are getting a lot of gas cutting. I would really give the barrel a once over as well. If the barrel has copper fowling in it you are going to get leading.

I got a load from Pat in Australia of 40 gr of 4350 and will try the load out when the weather improves. I'll post the results.

Take Care

Has anyone used 16 gr. of WC820 with the Lyman 314299 in the 303?

................Hey Skeet1, welcome to the board! You might PM Maven. Don't know if he has a 303 but he seems to put WC820 in everything short of his Wheaties in the morning. Even if he hasn't done the deed with a .303 he can probably give you a load for it :-)

I have a mount that is of unknown make,I would post a picture but I don't know how to,that works very well.It is nothing more than a piece of alloy that sits between the rear sight ears and on the stripper clip guide.It has not changed zero yet and my No.4 is my main hunter so it is a good thing.Just lately I have been playing with Ar2217(H1000) I think it is in the US and a full case,45grn under a 230grn CBE slug shoots well out to 300yards and one went through a piece of 5/16'' bisalloy plate at 100 like it wasn't there!!!
