quick sanity check, straight 6BR velocities

[foxguy]

Savage f-Class rifle, 28" barrel, 105 gr bullet seating is off the lands , 30 gr Varget, CCI 450 primer.
.350 MOA at 100 yards. 2850 FPS.

Remington 700 action. Benchmark 28” barrel. JGS no turn reamer. Lapua brass. 105 Berger vld’s 10 thou off. 30.4 grains N150 @ 2860. Shoots consistent and tiny enough to win local f class midrange matches. Others results vary. Every rifle is different. I tuned to the target before I owned a chrono.

Been reading too much over the past few days, head is spinning
Pretty new barrel, less than 100 rounds, 26" varmint contour, straight 6BR using Lapau brass, 450 CCI, mid 60s F today

105 B VLD -10 thou off lands
30 grains Varget, three shots avg = 2,775 fps, 30.4 gr Varget avg = 2,784 fps ... are those velocities in the ball park?

95 gr Berger VLD -10 off lands
29.7 gr Varget, six shot avg = 2,835 fps, 30.2 gr Varget six shot avg = 2,874 fps ... are those in the ball park?

Thx

Pretty much what I get with 107's.

If you do seating depth first, your powder windows will be wider. I don’t mean velocity because I couldnt care less, but the width of your accuracy nodes will be wider. I have testing this many, many times. Hope that helps.

How does your method start? Just a decent powder charge and adjusting oal to find tightest group? Usually oal is my last step

Yep. I’ll start with a luke warm charge and an appropriate depth and start backing up .002 at a time until I get 3 groups in a row that are just a little dot then I’ll load .001 shorter than the longest of those 3 and start my powder.

Might be the best thing I’ve ever done for improvement.

Appropriate length?…. For example, if it’s just a bench gun start with a square mark on the bullet. For VLD or hybrid in a hunting rifle start at the lands- you know, sensible haha.

If you do seating depth last, better have a heck of a forgiving combination. They exist, sure, but not worth rolling the dice to me.

Give it a try.

If, wanting 3,000 fps from 105's / 107's try,.. 40 grains of, StaBall in,.. a 6 XC
95 Bergers, go OVER, 3,100 fps with, 41 grs of StaBall ( 24 inch Barrel ) again from,.. a 6 XC
( My Coyote Load for, THIS,. Rifle )
107 gr. SMK's "Jammed" .012 / .015,.. Oh, My !!!

WHY do you insist on clouding up 6BR thread with useless info about the 6XC?
This info, in the hands of someone who may misread, could be dangerous!

I think the point of the post was if you want 3000 fps with a 105 get a 6xc. Not a 6br.

Than you sir, I will definitely give it a try

Again, we should learn to keep a thread on the correct path. Where did the OP mention 3,000FPS?
Where did the OP mention comparisons to he 6XC?
You were very good with the post on accuracy needs for the 6BR but cloud it up with YOUR FAVORITE!

Sanity check is the name of the thread.
