isapore 7.62x51 are they any good ive shot 1 308 hand load 150 gr with 43grs powder?

I have a 64 Ishapore 2a. Great gun. Got me addicted to enfields. The first group was a five shot group that measured 1 1/16" at 100 yards with winchester white box ammo with open sights. In theory, the gun is designed as a 7.62 nato, which has lower pressures than the 308 win. Lots of people shoot 308 win out of them with success, but I would recommend you stick with surplus ammo, or low pressure reloads. The 7.62 nato ammo tends to be cheaper than 308 win anyways. Now beware if you try to reload the 7.62 brass, it is thicker than 308, thus the pressures will be higher with the same reloading recipe. Keep the brass seperate, and reload accordingly. You say you need a clip, I will assume you mean mag. They are available from almost any gun supplier. Try numrich, springfield sporters, ebay, gunbroker, etc. There are 10 round aftermarket mags, while the originals are 12 rounds.

Sounds to me that you have a very limited experience with firearms, the 7.62 x 51 is the military version of the commercial 308 Winchester factory round, unless the action is a single locking lug as opposed to a dual locking lug design then there should be no problem, the bore sighting is no excuse for the actual firing of the rifle over the bench rest with good sand bags, this sounds to me like a conversion from the Enfield Mark 3 round(303 british) to the 308 Winchester, the Enfield is a very strong action but not the best suited for conversion to a sporting rifle, for one there is no clip the 303 was loaded by stripper clip, there must have been extensive gunsmithing done especially to the bolt face, the rimmed round of the Enfield is larger in diameter than the 308 Winchester round and if it is the two piece stock there is not much you can do for buying a clip for it, and it is refered as caliber not guage that is a term used for shotguns, unless you are talking about a head spacing guage, and then you would be forced to buy all three guage's go,field and the no go guage, if the latter fits?(no go guage) I would not use it because it has excessive headspace, and you could end up having a head case separation, you need to take it to a qualified gun smith and have him check the head spacing on it but there is no clip that is readly available for that particular rifle. (caveat emptor) buyer beware

The Ishapore "2A" rifles manufactured and chambered for 7.61x51mmNATO cartridges were made with better steel receivers than previous Lee-Enfield rifles. In other words, they used stronger steel from the start, so the rifles could handle the pressures of the 7.62x51mmNATO cartridge.

It never hurts to have a competent gunsmith inspect a rifle and check that the bolt headspacing meets specifications and there are no other problems. The same gunsmith could order a magazine for your rifle and make sure it fits properly.

You should go to a gunsmith and get up front information. If the cases didn't split everything could be o.k. get you Magazine from a store with a gunsmith.
