.270win at slower velocitys?

Il do a test later, load the round into the chamber an close the bolt, see if the mark is there. that would determine a primer that's not seated enough, although all primers look to be pretty nicely seated. so maybe upon firing they are puffing a bit maybe.

Not too much of a drama though I take it?


Dogleg, theres no way id sight a rifle in around 3 inches high at 100. personally.

Maybe if it was called for long range sheep hunting or something then Yes I could see that working for me.

Imo the 3 inch above line of sight is too much for my liking :) thanks though!

cheers

Yeah rightio, im going to do some testing an see how I go for a decent accuracy. I might be able to get around 2900 with a max load but see how the pressure signs are by then.

Im actually thinking that having the 100yr velocity wont hurt, especially with the cup an core Corelokt projectile, which isn't the hardest projectile around by any means but may penetrate a little better!?


I also read up on a google search about something along the lines of with a 2700fps start , the drop at 300y was around 15 inch and with a 3000fps the drop at 300 was 11inch... so that doesn't really worry me an I doubt shots will go over 300 very often.


Was hoping to load up some rounds tonight but I did forget the Macrometer and cant be 100% my brass is short enough to be under Max length, although its only once fired brass!?? :/

hopefully tomorrow.

As you know, Varget is too fast burning to be ideal in a 270W.
A 270 Winchester is actually over capacity, as compared to calibre. Thus, faster burning powder will build pressure very rapidly as powder is increased. One would have to be very careful in building up loads in a 270, using powder such as Varget.
The fastest powder I would use for normal 270 loads would be 4350, and much prefer H4831, or other powders of that burning rate.
270 cases do grow fairly fast with shooting, but I would not even bother to measure brass that has only had one firing.
 
Things have been going well with the 270 so far, the load is continuing to be accurate. Im yet to shoot it out to 300 although once the wind stops for an arvo il be sure to do a 200m test.

Ive shot some foxes with the loads and also a fallow deer, almost got to send one into a Sambar doe yesty evening but wasnt too be!


I just shot a Corelokt into a pile of years an years old Sawdust from an Old Mill, Il dig the projectile out an take a photo, as the top is crusty an underneath is wet an rather solid.
From 77meters it looks to have penetrated around 10 inches... Aught to do the trick on any critter i think.

BTW still havnt Chrono'd the load.
 
Most deer here in Ontario I talk to refuse to go down unless a 130gr .270 win. is going 3000 fps at muzzle or more so forget the varget and go with the h4831 or imr4831.

I didn't get to ask this guy what he thought about it at 2800-2900 fps :)

Maybe one day il try some slower powders an bigger projectiles! if I chrono an find im above 2850 at the muzzle, ill be happy, an closer to 2900 and il write a song an dance about it.. :)

I get your point though, ive read numerous forums re speeds for 270s

WL,

i was like you no way more than 1 inch over at 100 metres ... split with 2 inches ... and try it ... then try 3 inches if you dare lol ...

but the 270 is a magic wonder that you have to try to be sure what the guys were taking about ...

all the best.

I to have a .270 win and most of my deer have been shot with hornady 140 grain btsp I do reload for .308 to so I have some varget . I was thinking about using it for bullets in the 90,100 or 110 grain weight range ,even this range of bullets will kill deer with no problem.
 
270 Win is an extremely interesting cartridge to reload for since you can get good accuracy and velocity with a wide range of powders.
That being said, you should definitively try slower burning H4350 (and H4831) simply because higher loading density often means higher velocity and improved accuracy.
Varget is perfect for 223 Rem and 308 Win but a bit slow for overbore cartridges such as 243 Win and 270 Win.

There is data to support using a slower powder, but the OP appears to trying to consolidate his powder collection. Varget, as demonstrated, will do quite well in .270, as well as in many other calibres. I find it is very consistent over temperature spreads, which means my first shot ends up where I want it, regardless of the time of day I take it. To buy an entirely different powder for sight performance gains in a given calibre seems an exercise in inefficiency, considering not all powders are always readily available...

WL , looks like your load did exactly what it was supposed to.
Cheers mate.
 
Hi, IR Thanks mate. Your on the same page :)

I had perfect conditions at 8pm tonight an hour before dark an set up the target at 200m (190ranged) and got the Remington out for a shoot.

I shot 6 rounds all up, 2 straight up and then a 4 shot group after I had checked the target (drove up in ute). The 2nd shot felt Good, First not so..
I gave the rifle 10 minutes to cool an then pretty much fired the 4 allowing minimum time for the barrel to cool in between the first 2 an last 2 shots. The 4th shot I knew was a flyer from let off & expected it further out!

Heres a photo of the Target, a shoe box, with A4 paper. The group below is a shoot at 100m, the X is the 200m Target.

Fair to Say im Wrapt with this load!!! I'm going to measure the drop shortly an see if someone can put me in a rough velocity range??? using a App or program but il save that until later.

I rekon im a average shot too An id almost say the rifle would shoot better than that but I cant, so I wont.

Whattyas think?
Rem 700 sps .270 Win 3-9x50 VX2

130gr Core Lokt
45GR- 2208/Varget
Win cases
9 1/2 Primers
'partially FLS' very slight stiff bolt closure*

Cheers

When it comes to choosing a powder for a specific application, the acceptable range of powders is actually quite broad, and you have to really work at it to make the "wrong" choice. The fastest powder I've every used with 130s in a .270 was 3031! By comparison, Varget burns like charcoal. Unfortunately I didn't keep the records, but IIRC, the load (44-45 grs?) shot well, under 1.5 MOA, (from prone in the winter) and velocity was sufficient that the drop at 300 was manageable, but I can't recall exactly what is was. The rifle was an old Mauser of uncertain lineage in a sporter stock, and I've been pestering the guy I sold it to to sell it back to me, with no luck thus far. Some rifles just feel right, and when you find one, you shouldn't let it slip through your fingers!

WL, your load seems to meet the requirements of accuracy and velocity. The truth of the matter is, that even if 250 fps slower, the load would be lethal on deer sized game over normal hunting ranges. I loaded up some 130 TTSXs @ 2600 in .30/06 for my recoil shy nephew. That load has accounted for both whitetail and mule deer in BC.
 
Photos of the Corelokts.
a 300wsm 150gr On the Left in both, and the 130gr 270win on the Right.

300wsm was out of a sambar Deer double lounged at 230ms
270 was into years old sawmill sawdust and was quite hard on the surface an solidly moist all the way in. penetrated around 2 ft! at 80ms
