Berger 90gr BT for 300 yard score matches using 6BR

[Raydee]

Now that our summer league is over I plan to test out some new loads. I just bought a couple boxes of Berger 90gr BT and I am wondering what loads you guys have tried with these bullets. I am using a 8 twist, 26" barrel and would like to use Varget or VV-N150. GRT shows a load at 31 grains of N150, which is a full grain hotter than what I was shooting with the Berger 105gr BT, does that sound right?

Was planning to do a Boyer style load development, do you think 1/2 grain increments is too coarse?

I’d do .3 increments. I’ve ran over 30 with n150 and 105’s before testing. Think I went up to 30.6 with out issues as far as pressure. I’d start low and work up though as usual. No sense in being hard on brass unless you need speed.

31.0 of Varget and a 90 Berger has been real stout in a few bbls for me in a 6 BR. @Shooter13

LOL just getting ready to tell him the same thing! That gun has gone to a new home at Matt didn't have time to shoot it but I have another 8 twist coming and may ship it to you for that "magic reamer"

Keep us posted on your results. For comparison I’m at 30.4 N140 with 105 hybrids @2830FPS. 26” 7.83 Brux

I did very well years ago shooting 500 yd matches with a 6 BR, 88 gr Berger, and VV135. Never forget.....Its the Indian.

Remember what your load was? I got some of that on hand

No that was 25 years ago but I never saved on powder, lol.

Try n-540 with'em...
I don't load too hot but have shot it for 20 or so years...31.8 grs...but work up

I did 90gr bt at 100m in a br match. Very easy to tune. 30gr n140.

The Indian should maybe try some RL15. Work your way but somewhere around 31 grains..

When shooting 90 grain bullets, I increased the powder charge that I use for the 105 class Bullets by one and 1/2 grains,,,, Roger
