270 WSM 20”

Considering factory options to turn into a 20” hunting rifle that you can stretch easily to 300m with up to 140-150gr bullet but also trying to find a balance between recoil. So been playing with the 6.5 PRC and unfortunately not to many factory 7mm options. So would you conquer if you divide?

Had a quick play around on Quickload with 270 WSM and can get about 2900fps out of 20” barrel for the 150gr ABLR, but the 1:10 twist will most likely present a challenge in stabilising the bullet, but there are some other options as well. Suppose a 284 or SAUM would be ideal but no factory options. Shortening a factory 6.5 PRC is also a option, but components seems to be a challenge.

Any real world experience with a 270 wsm?

Greg Duley uses a standard .270 with an 18" barrel on his TV shows. Quoted as "Hornady 145gn ELD-X driven by 57 to 58gns of Superformance powder in Norma brass with Federal Fed 210 primers for 2925fps".

That's pretty useful for a lot less powder than what you are suggesting.

If you are only thinking 300 just about army short action round in 6.5 or 7mmm will get you there. Any of the 08 cases would be fine. As much as I don't really like it the creedmore would probably be spot on particularly if you want to keep the recoil down

I can categorically state for A FACT your standard garden variety poohseventy with 140grn loads will get your deer at 350 yards with no fuss or bother and not huge amount of recoil either...suppressed,the recoil wont even be enough to bother slimmer built folks.

oh and you dont need to use chronicgraph or range finders or twiddle n fiddle with knobs to do it either...point n shoot...at 270 yards it be pretty much bang on if 2.5-3" high at hundy...out at 350...top of shoulder..... its not rocket science and folks been doing it for what???50 years??? now.

I found the wsm a horrid rifle to shoot while it was accurate it just wasnt enjoyable even with a can the 150lrab is a good pick I'd do 270 308 saum or as above any 08 based case for that range

10 twist will stabilise the lrab just fine. With the right powder you'd get a lot more than 2900fps out of it also. I used to use the lrab exclusively in my 19" barrel 270win and pushed them at 2850 with 2209 no worries.

And that would be more like a 600yd capable round wouldn't it?

With any load you are really only loosing 50yards range at most cutting a 270win from 22-20inches.

but you also bring noise 2" closer to your ears...........

From memory it had 1000ftlbs to 850yds

There's obviously more to this yarn. 300m is bread and butter for teency wee 6.5s

If you just want one then go for it. It was overbore before it was cut to 20" so there will be some exhaust gasses to get rid of.

If you want a 300 yd magnum maybe a 223 wssm
A 6.5 grendel has 1000ft lb at 300 maybe even a 762x39 or 223 shooting some 70 something gr pills

Factory Tikka t3x elite .270 with the 20" barrel gets 2800 fps with factory Hornady 145gr eldx which the two longest shots have been 693 yards and 680 yards. 1 made it about 15 metres and the other flopped on the spot.
Loaded up some 140gr bergers which are doing 2900 fps. That isn't a max load either just the more accurate load.
You wouldn't catch me using a magnum for 300 yards. Extra boot, bigger suppressor. I shoot comfortably out to 500 yards with my 16" barrel .308 and many are doing the same range with 7mm08s and 6.5s.

Just chop it. It will still go bang but you will like it more
I dont regret chopping my kimber 300wsm to 20 inches and the deer still fall over. I think its about perfect.

Is this thing getting a suppressor? Are we just assuming that?

Because without one it will be like firing a small rocket into your shoulder.

Curious trade off with a can between shortening to a practical length and then really needing it due to muzzle blast.

6.5x47 will make 2800 with a 140 and just over 40gr of powder and it doesn't need more than 20" of barrel.

It's assumed the Creedmore is the same.

For an extra ten grains of projectile and 100ft per sec, how much extra powder is this 270 WSM burning?

Because a 140gr 6.5 load is a very effective 300m killer

19-20" 300wsm is one of the greatest guns around. Good mix of speed and compactness

The intended purpose for this rifle will be to hunt stags with, but also be able to double as a bush rifle. So in my mind looking for something with enough punch, but still enjoyable to shoot. Yes, would like to suppress the rifle. Preferably looking at a calibre that is available in a factory option. So option one would be a 6.5 PRC or 6.5x284 with 150-160gr hunting bullets, but very limited SS options in a PRC and 6.5x284 options. The other alternatives would be a 6.5CM or my favourite the 6.5x47,but perhaps these will not provide enough velocity en energy out of the 150-160gr bullets. The next logical step and ideal would be a 7SAUM or 284 Win, but these would require custom option. The 7-08 is another option but in my mind not much between it and 308. The 270WIN as some have mentioned is also a option, but have a few friends with 270WSM that really rate them. So yea, the 270WSM could potentially be a compromise and solution.

Literally came home from the range shooting my mates 21” 270wsm tikka. Shooting the Federal premium 140gr hybrid hunter the velocities were 3065, 3058, 3065. .25 inch group

Ive got an xbolt .270wsm that I docked to 22". It performs very well and the difference between it and a 6.5PRC is negligible. 150's @3k and my favourite 129 Barnes LRX @ 3.3k. Flattens everything out to the 475 yds Ive used it.

I would still though recommend a docked standard .270 for efficiency.

Attachment 155057 that is the group from tonight. Red square is 1”. 140gr at 3065 is plenty. Yes that is 3 shots at 100m and the round above was the first sighted at 100m, not part of the group. Thinking of doing it for myself at 20” now

I have had a Win Extreme 270WSM l docked to 20" for use with a suppressor for years & have taken everything from rabbit to Buffalo with it , from memory it spits out 140grn at just over 3000fps ,taken Deer at 450 yds & Tahr at 480yds.IMO you should look long & hard at a 7/08 or 308 that will do all you want to do.

IMO from what info you have given l would look seriously at a 7/08 or 308 & recently there have been some bargain proven rifles for sale here on the forum.

I had a brief play with some load development loads for my 21" standard 270 today. Around 58.5 grains of Superformance will send an 140 AB at around 3060. I went up to 3110 but this was too high and starting to get a slight scrape.

hey bro, thats 7mm-08 country :D :P
