I meant 270 wsm brass sorry about that
Hell yeah, thats the way that is done!!!!I will never be without a .270. ..........
Here is a 2 shot group I made at 550 yards with my 270 WSM with 170 Bergers. View attachment 453921
I have a Benchmark 23" with 1:7.5 twist on my old 700 Rem 270 Win and was just able to get some of the 170 EOLs. My earlier chronographed velocity with the 170 Nosler Ballistic Tip was unimpressive. Since I can seat the bullets out to 3.65 COAL I assumed that I should likely be using more powder, but haven't found load data for that bullet and RL-26. Any suggestions on a reasonable starting load?The standard .270 Win in fast twist (1:8, 1:7) with plenty of magazine COAL >3.5" will perform at a whole different level than most expect. I built one and I knew it would be better but seriously not to the level achieved.
For example:
170EOL > 3,000 easily
156HH topped out at 3300
I ran quite a few ladders of different bullets that all performed better than expected due to increased CBTO and COAL.
The magical pixie dust RL26 is perfect marriage for maximum velocity. Just know when to say when on temp management.
270 Weatherby still works.
Check Berger, I believe they have load data with the bullet and RL26. I think I have their data, will check.I have a Benchmark 23" with 1:7.5 twist on my old 700 Rem 270 Win and was just able to get some of the 170 EOLs.

Thanks for the info I've thought about doing a 270 ackley as well I've really been researching/ wanting another 270 wsm but brass seems hard to find for it I looked again last night and couldn't find any instock
Thanks for your help. Berger didn't have data on-line for anything larger than 150gr, so I sent then a request for 170gr loading data. The 150VLDs shoot really well, but was hoping to take advantage of the 170's. Tried Magnum and Magpro. Magnum was accurate, but under 2600fps; hoping for better.Check Berger, I believe they have load data with the bullet and RL26. I think I have their data, will check.
This may not be helpful in the slightest as an apples to oranges comparison but a while back (okay ten years ago now) I experimented with the 180 woodleigh weldcore in 270 win. Again, 10 grains heavier, jacket waaaaaay thicker, and bearing surface multiple times longer probably. But still a data point. Best velocity came with rl25. 2600 fps in a 22 inch. I believe it was 57 grains in a Winchester caseThanks for your help. Berger didn't have data on-line for anything larger than 150gr, so I sent then a request for 170gr loading data.
