Thread: Starting from scratch

Hey team, I have some 170 EOL VLD's here thanks to Blackwatch Reloading that got them in for me. I'm thinking of building a rifle to suit them if I can track down a 1:8" barrel (any suggestions?) But in the meantime I'm keen to see how they go in my 85 (270wsm)
I can't find load data for them anywhere but 2225 seems to be the go to for heavy bullets in the wsm. My current load is 150VLD over 70.5gr 2225. Do you think I could load up a ladder starting at say 65gr and go from there? Or start lower? I'm not real keen on wasting a whole heap of them so don't want to start too low/high and end up going back to the drawing board too many times. Any suggestions appreciated.

The 170 EOL probably won't be worth worring about unless you are going to go with something like a 270 Allen Mag. I doubt if you can push them fast enough in a 270 WSM to give you enough of an advantage over the 150's.
What velocity do you think you will get from them? When I had my 7mm mag, a 180gr only gave an inch or two windage advantage over the 162gr because of the lower velocity. It wasn't until I re-chambered to 7RUM that I could push the 180gr fast enough to get enough advantage.
If you are going to re-barrel and want to run those 170gr EOL then thonk about something like a 300 Norma Mag necked down to 270. You would need to switch to a ball powder as some of the big stick powders like 2225, 2218 can cause powder bridging problems.
Check out Kirby Allen's webpage he has quite a bit of info about his 270 Allen Mag.

Current load, launched at 3080


170 launched at 2900


I see plenty of benefit...

If you can get them that fast it will be worth it.

Hey Ryan, give Hugh Bradley @Bradley Barrels a hola hrbradley.nz@gmail.com or 03 44 888 44, he has done some great work for me and will be doing another barrel soon. He's in Alexandra so not too far from you, talk to him he has plenty of years experience all his own barrels made to your requirements.

The ADI manual lists someloads for 180gr in 270WSM
2217 start 59 max 63 2,718 62,800psi
2225 start 62 max 65 2811 63,000psi

Their 160gr loads
2217 start 63 max 66.5 2913 63,200psi
2225 start 65 max 68.5 2989 62,600psi

For 150gr 2225 70.0 3.071 63,000psi so that data agrees with your current load. I'd split the difference between the 160 and 180gr loads start 63gr 2225 max 67?

Don't make me get the screenshot out @Gibo .....

27 Nosler? Ream the wsm?

If you have a look on long range shooting, you will find info on the matrix 165gr .277 Vld, , I still have 300 odd from when I wanted to play with them, never got round to it after purchasing a M70 in .264 win and .270wsm, the .264win shoot so well, I just sold the .270WSM,
Should be pretty close for your purposes, but back data off a bit, and build up carefully.
I know they wouldn't stable is a 270 win, with a 1-10, but will in a 270 WSM, exact words were push em hard,
Lilga I think, ? did a special run of 1-8 twist 270 barrels, I know at least one other USA manufacture has .277 with a faster twist, I looked into it a few years back. when I was keen on the matrix bullets,
It will probably be easier to just do a 280 or 280AI,
I like odd ball calibers,(.17 fireball, vartarg, 6x45, .264 win,300H&h, 358 win) but it isn't always the best, fastest and cheapest, way to get to the target.

Thanks, yea I can find quite a few manufacturers making 1:8 barrels but have no clue how to go about getting one. I got pretty excited about the idea of getting hold of a proof carbon but have been stopped in my tracks now as they tell me they cant/don't do a 1:8. Those Matrix look like the go for my current setup, have done a bit of research on them and they are designed to work in a 1:10 if pushed hard I just can't find where to get them!

Have you talked to Kiwi Greg? he gets a lot of barrels in.

That would be cool but need a long action
