I am shooting an Accumark and no matter what I have tried, I have not been able to duplicate either the velocity or accuracy of WBY factory with handloads. This is very frustrating because it is the first gun I've owned that I can say that about. My handloads don't do bad but not on par.

dont chase their velocity. 22 and a 130 xxx should be worth a try..

Just did a search on 270 Wby and found this data by you. I see you have used up to 73gr RL22 with a 150 gr bullet and are still with us. I used that load previously with a Hornady bullet and got 3225 fps with a 24" Mark V. However the load data I was looking at gave only 72.2 as a max and I backed off to that but never chronoed, just figured it was still 3200 or so. Thinking maybe you saw the same data and can reference it because for the life of me I can't remember or locate it.

Also, I just loaded some 130 Hornady Interlocks with 73 and 74gr RL22 to range test. Considering 73gr as apparently safe with the 150 IL I THINK I'm on safe ground with 74gr RL22 and the 130 Hornady. Also ended up about .100 off the lands due to the Weatherby throat. I hate having to guesstimate safe levels but the newest Hornady manual really seems ultra conservative on the 270 Wby. Any thoughts here??
Ever used H1000 in this caliber by chance??

I burned a lot of pwder when I got my 257 Roy in a Mark 5 years ago . Then a friend said a guy at the wby factory told him he should use 7828 . I tried it and it puts 120 gr NP's in the blck and real quick .

When I come by a No. One in 270 wby [ bought it for a donor ] I put 75 gr of IMR 7828 behind a 130 xxx which were the only 270 bullets I had and it produced a nice tight little group at an an average of 3415fps with ES of 40 . Thats for 3 shots .

I invested in a real good set trigger , put an AV Swaro on it and it is my main rifle. [ I still have a neat custom 7 mag barrel for a NO. one if anybody is interested!]
