Re: Who's played with Berger 155.5 30 cals
I've been shooting them in f/Tr competion since last August, and have nothing but praise for them. I built my current rifle to shoot the 155 lapua, and it didn't seem to care for that particular bullet, so I tried the then brand new 155.5 Berger. I'm shooting them out of a 31" 1-12" Broughton 5c at 3000 fps, and they have done extremly well for me in 2 Canadian Championships, as well as the F Class World Championships. In a nutshell, they jump extremly well, and shoot well ove a broad velocity range. About optimum seems to be 3000 fps and 0.030 jump. The US F/Tr team seems to think they're all right as well.

My brother has been shooting them in his Savage F/TR with RL15 at 3000 fps. Here is a picture of a 600 yard target that he shot a few weekends ago.
He compared them to the 155g Lapua and said the Bergers shot better for him.

Hey Matt!
The B155.5BT seems to be winning a lot of fans. I got in on some of the early samples Berger sent out for testing last year. I took my base B155VLD load - seated +0.010 into the lands, over 46.8gr Varget in a Lapua case, 210M, and backed it down a smidge to test the B155.5BT. After talking with some other people who had tried them, I decided to try 45-50 thou jump. I worked back up to 46.8gr Varget @ 2960fps (factory Savage 30" tube). They shot about 1/2-3/4 moa flatter than my 155VLD load; basically consistent with the increased BC. Wind deflection seemed a bit better as well - picked up a few points here and there which adds up over an agg.
The sweet bit for me is this: the bullet has a *very* short bearing surface - something like .265". My B155VLD load was compressed even at +0.010 into the lands - the same amount of powder in the same cases with the B155.5BT was not compressed, no longer jammed into the lands, but still actually longer in OAL. With the bullet seated that far off the lands, minute variations in seating depth don't really bother me any more.
I know I like the bullets, and as Matt indicated, the bullets did very well in competition - very well.

you're right Monty- anybody stuck w/ a short throat can really benifit from the 155.5 geometry.
