But the properties of the underlying barrel may change with heat, or are you saying that barrel steel is immune to expansion and contraction with heating and cooling?

I am interested. Cut or button rifled? What is the shank diameter?

Did you get any further with this? I loaded my 375 with the 300g TSX /RS60 and got up to 2611fps when I hit the first pressure signs. Haven’t had chance to group test it yet but looks promising!

Is it pink with spots? 🤮

I have had a 7RM for years and love it dearly. My son has just bought a 300 WSM with the intention to use it as a hill stalking rifle and I must say I am quite impressed so far. With minimal work up we have a load for the 130g TTSX that hovers at the 3600fps mark with no pressure signs whatsoever and 0.5-0.6 MOA accuracy. If I were looking to change I personally would seriously consider a WSM.

The comps so far have been out to 1000 but no further - can’t say whether this will always be the case. As Andy said the COF is only released on the day ( which is as it should be to avoid cheating.... I’ll say no more !! 🤭)

You are welcome, what calibre are you after??

Have you had a look at the Holts sealed bid auction under section 5. There are two single shot humane killers and a selection of revolvers that could be readily converted at sensible cost. Just a thought.... https://auctions.holtsauctioneers.com/asp/fullCatalogue.asp?salelot=S2020+++3826+&refno=++145777&saletype= https://auctions.holtsauctioneers.com/asp/fullCatalogue.asp?salelot=S2020+++3823+&refno=++152929&saletype= https://auctions.holtsauctioneers.com/asp/fullCatalogue.asp?salelot=S2020+++3847+&refno=++154380&saletype=

I would expect the longer 7RM case will be easier to get to feed than a short stumpy SAUM. You could consider a 7mm Practical (7mm-300 Win Mag) as I don’t think the case forming is arduous. The only disadvantage of the 7 Rem Mag is the belted case

Now bearing in mind Eskdalemuir is only a few degrees off the arctic circle 🐧 that would be a terrible and frankly not a very impressive sight 🤣🤣🤣

Which reticle, is it Mil or MOA and is the elevation CCW? Thanks

Looks very good, how many magic beans are needed to buy one?

I can only add that it is an awesome range to shoot on. The comment about the wind is bang on as when we were there for the SIS last month there were wind flags showing exact opposite directions separated by 100m in distance!! Made my head hurt!!! I look forward to seeing the moving target range in the flesh!! The possibilities at the range are endless

Are these still available??

Make and model might help

How low is x low?

That has been my experience with them as well. Very few roe deer take a step after being hit. I have never recovered a bullet yet. Mine are from a 20 inch barrel with 46g H4895 at 3000 FPS. My sons rifle worked well at 3050fps, also from a 20 inch tube

I have used this bullet quite a lot and have found the jump to lands or 50 to 80 thou to work well. I think giving these bullet a jump to lands is about avoiding a pressure spike as much as anything. Plugging the numbers in to Quickload it looks like you have some leeway to increase the powder charge a bit whilst watching for signs of pressure. I have found good results in two 308 win rifles at velocities around 3050fps (20 inch 1 in 10 twist) so it may be that you are just off a node. Half grain increments may also be a bit coarse to identify what is going on, Personally I use 0.2 to 0.3 grain increments. It sounds like you have some chronograph data, what were the SD and ES numbers like? I have also seen lateral displacement between different bullets, that at least in my lighter profile stalking rifle is very consistent. I put it down to differing harmonics and dont lose much sleep over it.

High mag scopes have a very narrow field of view which makes target location sometimes slow. The red dot allows rapid alignment of the high Mag scope with the target at which point the shooter drops onto the primary scope to take the shot

I may know where a wood stock off a 308 may become available. It is a sporter weight barrel. Let me know if you are interested.

How do you think the gas was leaking back to cut the bolt face? I have just started using Murom primers and find them a tighter fit in primer pockets than CCI or Federal. I haven’t seen any that have pierced so can’t see how the primer choice could cause the effect you describe unless the primer pockets were already shagged?

can you give me internal and external measurements and weight please Thanks

Nice sounding project - have you considered 300 Norma??
