The rifle has grouped exceptionally!
If you go back a few pages I've documented full load workup with several bullet & powder combinations.

I did shortly after my last post on this thread. Not much of a test, but I did take an axis deer at 320yds with the 270 ELDx at 2700fps muzzle ~2400fps impact. Not even a challenge for the ELDx. Caliber entrance and about 1" exit on a back of lung and liver hit. I was really hoping for a 600+ yd shot, but the vegetation was thicker than expected and most shot opportunities were at slowly moving animals. They never want to stop in the open lane!
Since that time, I have ran the 270 ELDx up to 2917fps with 85gr R26. No real pressure signs, but Rich saw pressure at 86gr with the 285gr eld, so I think that's about max. I want to try some faster powders, I have R17 on hand and given where I hunt, temp stability isn't an issue, so I'm going to try it as well. I'll post up when I get more data.
I really want to chop my 24" barrel to 20"…

Couple weights on these AB's, with the Reflex (14.9 oz), and with the Flush mount (11.1 oz).
I'll add an Armageddon Gear cover here soon too.

Went to check zero after Alaska. This rifle setup has been through commercial travel, bush flights, and 20+ days in the field since last zeroed. I did check after landing in the field, and it dropped right in the same group.
Before Alaska:
After Alaska:
First three shots with the suppressor:
I'll take that for a win! Looks like I could bring my current zero without the suppressor down 1/4 moa, and right 1/4 or so moa yet but it appears to have held same point of impact through everything.

I plan to make a separate write-up on my 33 SM adventure, but here's my ladder results. Maybe @IdahoTrecker can post this along with your data to the Sherman site. I agree that the 4350 burn rate is best in this cartridge. I have the .312 FB chamber. Data is from a MagnetoSpeed Sporter. My drops on the 81gr R26 270eldx load trued out to 1400yds as 2748fps with a .345G7.

Hi 300 driver, I was wondering if you could share you COAL for the 270 eld-x in this round? Thanks
