Now that Berger has the 135gr, of course.With out the Blackjacks is the 25GT still worth pursuing?
One day I’ll get around to trying one. Either that or a 25dasher.

If you are going with the Bergers I would have a new reamer made. The pressure issue I have been fighting may stem from a neck diameter issue. I Talked to a rifle builder and he was having the same problem with his 25x47 rifles after the 131s ran out. New reamer problem went away. apparently the theory is that the BJ and the Berger are at opposite ends of the tolerance and the Berger is thick enough to cause a small increase in neck diameter.With out the Blackjacks is the 25GT still worth pursuing?
It's a real shame to see such a good bullet die on the vine. I tried the Berger's and they did not shoot as well as the BJ's in my Black Jack reamed 25C. Decided to pull the barrel & play with 22 GT.If you are going with the Bergers I would have a new reamer made. The pressure issue I have been fighting may stem from a neck diameter issue.

it could also have been brass flow thickening the neck that just happened to appear at the same time as I switched to the Bergers. I may try neck turning or maybe having the neck of the chamber opened up.
I am surprised no one has bought the rights to start building that bullet. I hear Sierra was making them for BJ.It's a real shame to see such a good bullet die on the vine.

I believe Hornady is releasing a modern 25 cal bullet if they haven’t done so already.
I really haven’t done much with it over the last year. I was having problems getting the velocity I was using with the ace after switching to the bergers. The current theory I’m working on is that the longer bearing surface of the Berger is causing increased pressure. I had to drop the velocity to 2700 ish to get rid of pressure signs. I just haven’t had an empty receiver in a while to work on it.Debating on switching to this for a season since 135 bergers are much easier to get. How is the recoil and barrel life compared to 6GT running about 2900?
I am about to try some out. I’ll post up resultsAnyone running 134 elds in the 25GT?
looking at getting one built, seems the right balance of recoil, case fill and velocity for what I do
Tried the 134s today. I shot a ladder looking at velocities and pressure limits. 36.9 and 37.2 were just over 100% capacity. (Very light crunch on bullet seating) round was super consistent had no problem keeping them all on an 8x12 plate at 500. Could spot trace easily up until 36 grains. Minimal recoil in 21# rifle with ACE Brake. All and all very similar velocities to the black jack bullets. Never saw any bad pressure signs maybe slightly flat primers. At 36.6 the blackjacks did 2780, the bergers (with pressure do 2722, and the Hornady do 2740.Anyone running 134 elds in the 25GT?

What do you think? Are you going to start running the 25gt in comps again?Tried the 134s today. I shot a ladder looking at velocities and pressure limits. 36.9 and 37.2 were just over 100% capacity.

I am going to give the Hornady a shot a local comp coming up. I have a lot of bergers and I might give them a shot at a speed that doesn’t show pressure. (2650ish)What do you think? Are you going to start running the 25gt in comps again?
