Borden BR vs Bat : 6br benchrest build

[muddy72]

Jim also has a BRL for the 30-06 etc. I have a single shot Alpine and I'm about to order a lefty BRM. The Bordens are nice folks to work with for sure!

Also the BR is slightly shorter than the BRM overall length so your ports are smaller and I have heard the BR uses a xp100 length bolt and the BRM is a 700 length bolt.

If you get a Borden I would recommend the BRM.

One difference I have run into between Borden and my Bats is the Borden will show pressure faster than my Bats would, and this pressure would be in the form of stiff bolt lift. I can't put my finger on the exact cause but my thought is the Borden bumps have such tight lock up it may be the cause. I had it happen over 6 barrels and in 6 BRX and 6BRDX.

It is not a big deal as I do not run the upper end but it was something note worthy.

Good Luck and enjoy!

I have two Bat and one Borden

The Bat seems more prone to galling. Or maybe I must be more careful. Both are fine actions, but my next will be a Borden

Alex,
I don't know what to say, maybe it was just the action I had. I had barrels cut with the same reamers between the LG and HG and the Borden always would have stiffer bolt lift first.

The Borden trigger timing is second to none though, they are so smooth on close it is incredible. I like the Bat ds actions though since they come with different trigger hangers you can get them timed pretty close and they definitely open very light and smooth with the roller cocking piece.

OP,,,my advice is to get a Panda action and never have to worry about any of the nonsense of timing etc,,,,Roger

On the Bat you just need to re cut the cocking ramp, clearance the action and shroud then screw in the firing pin and you can get to that .250 mark. The new pins are heavier as well. With the melonite you can overcome the galling and stickiness also. I thought the roller cocking piece would help. I had one on my mb, but I could not feel a difference between a non roller. The key for opening smoothness is the right geometry of the ramp. If you use some layout blue on a cocking ramp and open the bolt you can see how the cocking piece rides the ramp. If its not perfect the bolt can get very hard to open. One thing that helped cocking on my MB is Dwight Scott bushed the shroud so the firing pin is guided like a Remington and not by the cocking piece in the shroud. That made a big difference in cocking that action.

Alex, you talking about the rifle you sold me here?

 

[Alex Wheeler]

Yes Michael, your rifle has been "fixed" lots of work into that action ;D

It sure is smooth, like $hit through a goose!

What is the lead time for a Borden BR?

 

[R.Morehouse]

Give Jim a call. He might have one on his desk....

 

[muddy72]

He had 4 on his web the other day 1 was a lefty. 12 weeks to order, I hear maybe less!

I'm picking up my BR Action on tuesday. Jimmy told me in the beginning of November that it would be about three months. Considering he also had to polish the action, pin a recoil lug on and attach a picatinny rail, as well as time up my Bix trigger add to that the fact his EDM machine was on the fritz for a week or so, I would say his estimate was spot on. I've known Jim a long time and he has always been a man of his word. Now I can't wait to be shooting one of his beautiful actions.

Dallas, that's funny because I have seen the opposite. My 300 wsm with 215 hybrids has not ever given a stiff bolt even with 69 grains of H4831sc! It had a hell of and ejector mark though! ;D

Mind me asking what velocity you were getting with the WSM sir? And was this in a BR rig?
