What loads are you planning on using in this rifle.

I Haven’t even begun to think of what I might use yet.

I do like flat based bullets for up to 675y.
But I also like Hornadys ELD line up.
I’m a certified “fanboy” of the 147eldm’s in my tikka t3 varmint in 6.5x55!!

I will see what twist I have and work around that.

Don't forget these rifles were only proofed for the 144gn NATO round. In reality they are 303 Brit. When the change over to NATO ammo the range shooters who wanted their rifles converted in Australia had to send them to Lithgow for the conversion,. Not all passed proof and were not returned. If your rifle did not have the proof stamp you were kicked of the mound NO DEBATE.

Thanks!
I’ll be careful, no sense “hot rodding” it, it’ll just be a fun mid range rifle and just “cuz”

I wouldn't touch the shoulder at all. Lap the washer with fine emery paper on a dead flat surface such as a piece of heavy plate glass, lapping plate or gauge block. A piece of very fine-grained granite countertop can be a cheap option too; a sink cut-out for example.

That way you are taking off thousandths at a time and can't go too far, too quickly as can easily happen in a lathe, apart from the alignment issues with a round, tapered exterior.

Not gonna lie, this is exactly what I was going to do!

I have a piece of refrigerator shelf plate in my shop for these very purposes. I have “lapped” many M14 and M1 Garand gas locks this way to snug up perfectly.

Although I have a lots of experience trimming shoulders in the lathe, lapping the washer has the added bonus of not modifying the original barrel.

Thanks!!
