Thread: Getting velocity out my .270

  1. #1

    Getting velocity out my .270

    I am having problems getting good velocity out my .270 when loading, roughly getting 400fps short of book, I have a sako 85 with a 20inch barrel, I have tried h4350 and N160 anyone have any suggestions?

    Cheers

    Tis an easy one use faster powders.

    However you had better face it that it appears you have a "Slow" barrel.

    In my 20" barrelled BSA CF2 I used H380 to good effect. H380 can be used with 130, 140 and 150 grain bullets.

    Most of the quoted velocities assume a 24" barrel, so you will always be under these with a 20" barrel - try 60gns of H4831SC and a CCI BR2 large rifle primer under a 130gn bullet. That recipe gives me 3000FPS from my 20" barrelled .270 but the load is near max' so you might want to start at 59 gns and work up although dead-on 60gns seems to be the sweet spot in most .270 I've tried this in.

    Hi Laird,

    I have the same rifle and calibre.

    I use 60gr H4831sc with CCI primers, 130gn Sierra gameking and they do the job very well. I seat the bullet very close to the lands and I haven't had any issues with the combination. I am not sure what the velocity is as I have never used a chrono but I don't have to think a great deal about shots out to 250yds.

    Adamant's advice is good. He helped me determine my sweet spot - also true about the max load. work up with caution obviously.

    Agreed about the "working up" part but drop it more than one grain. Reduce it by at least 5% and see how that works for you.~Muir

    Did nobody tell you to buy a good 270 (think about it)

    Hi laird have you tried using reloader22 im using 58.5 and 59grns behind a 130grn sierra gameking and getting good groups at 100yards, also 58grns of rl22 is giving good accuracy and i would assume that they are over 3000fps i have 20inch t3. when i get a chronograph i will let you know the velocities, if muir is reading this he may know the velocities and have a better idea hope this helps.

    i use 56gn h4350 rws brass cci primmers and 110gn v-max with great effect work in both sako 75 and browning x-bolt
