Hey all.

I bought an Eddystone P-14 some time ago. When I slugged the bore and found out it was .315's wide, I immediately knew why this rifle wasn't grouping as well as my No4 Mk1 which is in the high .311's range.

I don't want to use cast lead, nor can I make my own. I'd prefer a jacketed round... unless some of you can convince me otherwise. Also, I'm not hunting with this, so it's 100m and 200m range practice only.

Anyways, the bore on this 92 year old rifle is nearly pristine, and it would be a shame to let it go unused. So what are my options?

Will the .312 bullets from Hornady do? What about a 100grn .314 (.32) bullet? Stupid question: will .318's do? Or is that pushing it? Has anyone used Sellier & Bellot bullets with much success?

One last one: Is there a 174gr flat based FMJ bullet out there that will replicate the Mk7 service round? Every 174gr FMJ bullet I have found so far has been boat-tailed.
 
Contact Steve at .303british.com. Add the W's. He's making .314" 200 grain jacketed bullets that are made specifically for high bore diameters.
"...will .318's do?..." No. Too big.
"...has been boat-tailed..." That's because the VIII ammo used a BT bullet. Your rifle won't notice the difference. It'll likely shoot better too. None of 'em are of any use to you anyway. They're all .311" or .312". The gases will blast around a .312" bullet as it rattles down the barrel of your rifle.
 
You need to determine your chamber's neck diameter to see if it'll accomodate bullets sized to your bore.

As soon as you ruled out cast bullets, you pretty much ruled out shooting it. You could try sizing down jacketed bullets for the 32 Special or 8mm in a custom 0.315" sizer, but aside from that, I can only think of cast.
 
I'm assuming that I need to measure the neck sizes of some once fired brass from this rifle?

That's one way. Using the same brand of brass, compare the neck diameters of a sized case with a 0.311" bullet in place with that of a fired case. If you have greater than 0.005" difference between the two, you should be ok with a 0.315" bullet. The neck springs back a bit, so that would give you 0.002"+ clearance - tight, but safe.
 
Rough up .312 bullets with a bastard file and paper patch them till they're .315" when dry................................Harold
 
Tyler; Andy has given sound advice on checking neck diameter/clearance before trying to shoot a .315 diameter bullet. That being said, I would not be a bit surprised if that .314" diameter bullet Steve Redgwell makes shoots very well in that oversized tube of yours. I would send you some to try, but only have the .313" ones, since my bores are that size. Regards, Eagleye.
