7mm rem mag load - hill stalking

[Essexsussex]

Hi all

Looking for recommended recipe for my 7mm rem mag to work up.

It is only used for hill stalking and I had thought go for 120gr and try and achieve a longer point blank than the heavier bullets. I have been using r19 and 140gr Sierra game kings. Haven’t yet found a really accurate load (haven’t tried that hard) but am coming to the end of my powder so thought I would start again.

Lee loader loading as well, but with scales at least!

A light copper bullet around 120-130gr from GS Custom or Barnes @ about 3400+ fps would be my choice

How far you wanting to shoot them out to ?

I'll be doing some load development soon and intend to use Vhit 160 and was looking at 140/145g bullets.

Sub 200m would be normal but there are occasions when reaching to 250m is helpful.

That’s interesting / helpful as n160 is what I use for my 6.5x55 - I didn’t see it on the Sierra chart though.

That is exactly what I use and it works really well. 120g Barnes TTSX with around 70 grains of H4831SC in a Hornady case with Federal Magnum primers gives me a smidge under 3400fps. Recoil is light and I can see the strike pretty much every time. Nothing has ever needed a second shot yet and I have only had a couple run at the shot but that was only 20 metres or so

Yes, similar experience with my wannabe 7 Rem Mag (270 Win) shooting 110gr GSC Bullets @ 3450fps approx

Oddly enough I was texting with Ronin about just this topic this morning and his medicine for Reds is the 95g GS at something like 3400 out of a 6.5/284. We have all clearly reached virtually the same answer independently

Definitely! Not many are interested but it works so well. The 62gr GSC @3350fps out of my 6mm works just as well and I'd happily use it on larger deer if I was allowed to.

Which 6mm ?
Many years ago I bought a copy of Guns & Ammo which had an article on the 6mm Mach IV which if I recall correctly was a 7mm RM necked down to 6mm. Oddly enough he had to use Barnes X bullets to get them to arrive at all!! I recall the terminal effects were decisive

Why not zero at 200. I think it’s 1.5 inch high at 100 and 6 inch drop 300 ish.

A 6x45, quite a bit tamer but just as deadly

You might be set on the lighter bullets, but i shoot 180 berger hybrids through my tikka at 3016fps using a healthy dose of rl33. Amazing on big game.

Jeez that sounds like a stiff load! I thought I was bad getting that velocity with a 162g bullet!!

 

[Uncas]

A 120gr bullet at 2'900fps will drop 10 inches and drift 12/14 inches in a 15/20 mph wind at 300 yds,
Why do some of you insist on using silly light little bullets for a fine game animal like reds,
Is this the responsible face of shooting these day's.

I can't see the point of having a 7mm RM and yet shooting .25-06 (120 grain) or .270 WCF (140 grain) bullet weight loads through it.

Better by far to use the huge advantage "a 7mm" gives over both (and over the .264 Winchester Magnum) in weight to length and calibre ratio and as a minimum use a 160 grain bullet.

The question I ask the OP is what is his barrel length?

Yup its pretty high pressure, but thats where it shoots amazing and getting great velocity. Haha yep i was getting 3080 with 162 eldx prior to the berger hybrid, they did well on game too.

24 inch (Husqvarna 1900 standard!)

This isn't just my theory. Others has had similar ideas. At twenty-four inches, in a .284 bore, you've a "calibre length" of 84 whereas a ,270 WCF a "calibre length" of 86 and a 25-06 has a "calibre length" of 93. By contrast a .30-06 has a "calibre length" of 77.

So what this means is that IMHO your 7mm Remington Magnum will perform the same as a twenty-five inch barrel .30-06 but only as efficiently as a twenty-two inch .270 WCF or a twenty-one inch .25-06. But that for the same weight bullet that a twenty-four inch barrel .25-06 will perform as well as a twenty-six inch barrel 7mm Remington Magnum.

So what does this mean? It means this...or so the theory says. That with 160 grain and above bullets with your barrel length will give an efficiency edge over the same length .30-06 but that in 120 grain it won't perform as well as a .25-06 with a barrel of the same length.
