ON an earlier thread this week, it was asked about loads with W 748 in the 270. Our own Steve Riccardelli indicated he could find no load info on it, and indicated that Winchester did not recommend its use in a 270.



With ALL DUE respects to Steve and the wonderful resource of the site he maintains, I decided to try it out and see what results I got. I am sure he could not keep track of all powders, and can't say why Winchester has avoided its use in the 270. I can hypothesize that W 760 worked so well, why bother changing.



Noting its burn rate being slower than IMR 3031, I decided to use a mild low recommendation for the 270 as a point of reference and came up with a load of 44 grains of W 748 with a Hornady 130 gr SP bullet. Case was Remington, and primer was CCI large rifle.



Rifle was a Winchester Model 70 with a Boss on it.



The load chronographed at 2850 and 2867 for two shots across the chronograph.



2 groups of 4 shots each; shot at 50 yds measured .706 and .601 of an inch at the widest points. All holes were touching. The scope was a 4 x 40mm Simmons whitetail Classic. The Boss was set on ONE.



So In my conclusion, W 748 seems to do a good job in this 270. This 270 also is not one of my rifles that I consider to be real accurate. However, with the W 748 load, it appears to do a good job by any standards. Once again this is just this rifle.



Cheers and good shooting

A little addendum here after the points Mike 375 brought up.

I just wanted to see if W 748 was usable in the 270, so using my knoggin, I came up with the charge of 44 grains. If you go below this amount or above, use the common sense to work within increments with this.



Even when downloading, the slower the powder gets, the more careful you have to be "WORKING DOWN" , just like you would on 'WORKING UP" with faster powders.



If you don't know what you are doing then DON'T DO IT. The rest of the world can't be responsible for someone's lack of common sense, regardless of what their lawyer tells them,or they see on " THE PEOPLE'S COURT" OR ' JUDGE JUDY" OR "JUDGE JOE BROWN".

MIke,
thanks for adding that. I did point out the load was developed using the comparison to IMR 3031 burn rate. It should be known to work up if one wants to go further. Personally I have found in a lot of rifles that can hit 3000 or 3100 fps with a bullet, that in most instances velocity around 2800 fps seems to be a lot more accurate and the loss in point blank range is minimal.

Guess we have to keep tellling people to use their heads and work up. It just gets hard to try and remember to put in every little common sense safety detail you can, just incase some banana somewhere is not using his head and being stupid.

I am from the old school, I am responsible for my own safety, not every one else in the world. I have reloaded and found that even some loads posted in some manuals are not safe in some rifles way before the max load is reached. Other rifles you can go way over that max load, with a different seating depth ( out further) and still have a safe load. Of course you have a million people just waiting to say AH HA!, like they are some sort of self appointed watch dog.

Each one of us can also get hit broadside in our cars going to the store one day, however how many are going to choose to walk to the store instead, if it is 3 miles away?

Life has no guarantees, except you are going to die and hate politicians ( pay taxes, lol). However you can up your odds at delaying the first one by using the brain and the common sense the good Lord gave you instead of relying on lawyers to defend yourself against your own stupidity.

Cheers and Good shooting

Hey Sabot:

You are a Virginia boy. Liberal or not, you are O'Tay in my book.

I am sure you are aware there is a difference between being Liberal and Liberal without using common sense.

I am very tolerant of a lot of stuff, but not when it starts to defy common sense. I think every person has a right to dignity and a chance at opportunity in life. What I can't see is how I am suppose to take food off of my son's plate and give it to some bum who refuses to work to support himself or his family. So he sits on his ass, receives welfare and becomes a staunch democrat.

But what has that got to do with a 270, right? LoL.

Cheers and Good shooting ( you liberal commie you!)

Seafire -

Man, you got that right....the 270 is a piece of work no? It is often compared to the '06 and a lot of arguing ensues, but the 270 is really a different round than the '06.

In point of fact, the 270 shoots the same velocities and trajectories as the 300 Win Mag with bullets of equal sectional density. Folks comparing the .308 150 grainer with the 130 .277 are way off...the 130 has the same SD as the .308 165 grainer.

The 200 gr .308 is the same as the 160 gr .277 and at 2900 fps penetration on even Elk is the same. Kenetic energy doesn't mean squat, and once you have a ton its ALL penetration.

In the real world of hunting and killing, if you used the .308 one day and the 270 the next day for the next 50 years, your final analysis would be there is no practical difference in killing power and the difference in trajectory is such that you could wiggle on target as easy as you could wiggle off target with either....and the same thing applies to the 7x57, 30-06, 280, 284,and a host of other non magnum calibers and a few magnum calibers like the 7 Mag and the .264 comes to mind....but then if that was accepted by all it would ruin our little party around here...and we'd have to talk politics.

I agree in the East...out West is a different matter. The flatter trajectory of the 270 with bullets of decent sectional density gives it a definite advantage in the hands of the hunter-marksman.

I have nevef used it in a .270, because I have always considered it a bit "too fast". But I like 748 for sauch things as the .358 Winchester, for example. I did once develop a load with it and with WW760 for the .303 British with 180-grain Sierra bullets, both of which were tested in a Jungle Carbine. I was able to get equal velocities with both powders, but the WW748 load ruined cases due to stretching a lot sooner than did the 760 load. 760 never gave as good accuracy results as the 748 loads, however.

Ray,

There you go again...making sense. But wouldn't it be boring w/o there hypothetical (and not so hypotheteical) arguments/
