As a matter of interest, One on top of Two, what's the fill ratio with your load of RS52 in 243?

Pete

Which model is it?

Pete

I use one of these:

They often turn up on used lab eqpt sites, and being "industrial" are a lot more efficient than much of the new stuff to be found on ebay etc.

Pete

I'm happy with 1 MOA at 600yds on a windy day................

Pete

I've had a chrome-moly barrel that'd been stripped and polished. No sign of rust after years. The only maintenance needed was an occasional oily rag.

The action on my Musgrave is the same. I just pop it out of the stock from time to time to check the underside.

Pete

So was it blued beforehand, or is the action stainless steel?

Pete

Me too.........who knows, you could save someones life...........

Pete

Have you tried this?

An easy way to find optical centre. Then you can deduce how far out the mechanical centre is.

Mine's this size, and will take a laptop standing on end.

Pete

Ah, an excellent vintage.............good colour, excellent strength, but can be a little skittish when it comes to speed.............

Pete

I've had this time and again, so I'll now only buy stuff after ringing to ask if they have it in front of them...............which also means that I avoid those rainy day "impulse buys"😀

I have to say it's never happened when buying bullets and cases from www.ballisticservice24.eu.......

Pete

Light signs of use, has worn a UV filter from new, so pristine glass. Been on a 22 rimfire for a couple of years. Selling the rifle, so no longer needed.

In the past I got round this problem on a Tikka M595 and a Swing by putting a shim between the top of the trigger housing and the receiver to effectively drop the top sear a tad.

Takes a bit of trial and error, though, and will only work if the trigger is bolted to the receiver.

Pete

+ 1 for RS62........just started using this with 136 scenar "L"'s, and it looks very promising, and kinder on barrels.

Pete

6.5x47 is a great round. Have you tried 123 or 136 grain Scenars with RS60?

Pete

Unless you're absolutely desperate, I'd keep that...............what a beautiful piece.

I just read "A glimpse into the history", and it's great to see this type of shooting being kept alive.

Pete

James8870, that weight of bullet in that calibre at that speed would have me twitching every time I pulled the trigger.................something ain't right, and I hope it's the chrony............

I just ran your load through QL using the standard COL etc, and it says 2754fps and Pmax 62920. 6.5x47 CIP spec is 63091 psi, so it's already hotter than I would ever consider.

To get 2950fps, you're looking at 39.5 grains of Varget and a Pmax of 79899psi.............somewhere near proof pressure?

I know QL has it's limitations, but even so............

Pete

It's a chemical reaction, so no powder can be completely temperature stable...............some are reputedly better than others. When I know the forecast is for hot weather, I reduce the load slightly.

The receiver will get hot and also affect the temperature of the round (brass is a good conductor of heat), so the time taken to chamber and fire will also play a part.

Pete

Quickload, but read , study, and inwardly digest the manual, and start 10% lower............the most useful bit of shooting related s/ware I've come across. Covers almost every bullet & powder under the sun.

Second is Litz's tome "Applied Ballistics for Long Range Shooting", together with the included calculator CD.

All you'll ever need............

Pete

I flame mine in the dark so that I can see the actual colour. Gave up messing about with tempilaq..............the gas flame varies as the gun heats up, so keeping an eye on the colour and adjusting the exposure time works best for me. I'm on a batch of 6.5x47 cases that are still going strong after 22 firings, annealing after every 5 or 6.

Pete

I came to the same conclusion, albeit by a slightly more Heath Robinson approach involving a pair of long nosed pliers and a couple of burnt fingers.............

The Lyman melter got the salt up to 550C in around 25-30 mins at full throttle, but with the knob at 2/3rds of it's travel, the temp  swing between power on and power off was over 50C.

Needs more work.................I guess that when the melter is used for lead, it's nowhere near as critical.

Pete

I've shot my 6.5x47 at 1200yds using 123gn Scenars with 41.5 grains of RS60 at 3050fps. (30" 8-twist Lothar barrel, may not be safe in your rifle)

Wind was a big problem, although I did get one "V"..............According to Litz, they were doing 1240fps at 1200yds, so still just supersonic.

Pete

My trial run with molten salt definitely softened the neck/shoulder area. The difference was easily felt simply by squashing the neck before and after with a pair of long nosed pliers. (a dud case........)

As for annealing too much of the case body, jury is still out.............

Pete

63mm deep and 100mm diameter. It has a slight taper from top to bottom.
