on a 223 blot face?

[suburban bushwacker]

I've recently paid for a Heym SR21, a rifle Ive wanted to add to my collection for a while. It's in 223, at the price I paid I'm not overly optimistic about the barrel.

Which has set me thinking, with a 223 bolt face,

What would you choose any why?

17rem, 17fb, 6tcu, 300blk out, 17rem is fast becoming my favourite round, 300blk out is nice to shoot, 6 or even 7tcu has always interested me

Downside of the SR21, from memory, is that the barrel and receiver are all one piece so difficult to rebarrel.

.20 Practical?

Heym do use very good krupp steel in their barrels. Unless it has been totally abused I suspect it will shoot well.

If you really want an action on which to build a very nice little rifle then the SR 40 which is correctly scaled to the 223 cartridge. Downside is that they are often on the market. Those that have them hang on to them.

Alternatives to the 223 that use the 223 bolt face are the various wild cats which are essentially the 223 necked up. The most common is the 6x45. There is also the 6.5 Grendel which is a very capable little cartridge that far outperforms what it has any right to do. I think it uses a slightly larger diameter case so bolt face needs a little machining. @Edinburgh Rifles has a very nice little one built on the little Sako action.

I am sure there will be a 6.5 x45 ie the 223 case necked up to 6.5mm.

Correct.

It was designed as a ‘switch barrel’, by which they really meant ‘switch barrel & receiver’. It’s why it has the weird separate trigger unit.

I think I have seen them with replacement barrels, but I don’t think it’s a straightforward job.

It takes a lot to shoot out a .223! Even with barrels like 200 year old drainpipes they still have an ability to shoot well.

In the future, ask for barrel condition before buying

Be warned: the whole design is a bit peculiar.

They have a ‘removable’ barrel and receiver. The trigger unit remains in place. The receiver slots onto a little stud that sticks up out of the trigger unit. This can act as a fulcrum unless the bedding is PERFECT and front and rear action screws are torqued up very precisely. Even then, there is a lot of tension brought to bear on this one point.

This means that accuracy can be erratic. I had mine rebedded twice, and spent years and a horrible amount of money trying to get it sorted. It would shoot perfectly for 30-40 rounds, then start double grouping. I got rid of it in the end. A real shame - a stunning rifle that was beautifully made with very high quality components. Just let down by a flawed design.

I'm shooting a 6mm204 I bought second hand, and what a little cracker it is.
70 grain TNT at 3145 fps, and 69 grain Absolute Hammer driving band copper at 3305 fps! There isn't much that walks in NZ that isn't going to flatten inside 350m, that is for certain.
