Bulldog modification log .328 porting and more

Talked with JSAR today and next up will be a custom length titanium reservoir for pressures up to 4500psi. 

Now that's something that I've been waiting for. Are you in line to get one?

[PCPhack]

Thanks to ShakySarge, I have a steel one on the way (arrives today).

In general, it appears that the wear is from cocking, but the result is the same regardless; the worn levers are absolutely a probable failure mode.

Yes, just waiting on Jacob to post it.

Yes! So do I. And a big thank you to ShakySarge! I went through two levers while keeping my Bulldog in completely stock form and have never gone over a 3000psi fill. The first lever lasted only fifty shots. Truly looking forward to the new improved steel lever.
And looking forward to a new titanium reservoir, of course.

Eureka!!!! That was exactly the problem, the cheap aluminum lever! I have the first prototype completed and installed. Even with the hammer spring adjustment all the way in it cocks every time no problem. The issue was certainly that the aluminum had stretched just enough to prevent the sear from catching. I will make a couple more and you are certainly welcome to the next one no charge. Perhaps Travis will be interested in producing them in numbers. Either way, I will pump out some more for whoever else may want one in the mean time. Besides, it keeps me busy as I am fully retired and there isn't a lot to do in this town.

We are all over this! I think its very needed in high power applications. We don't have a bulldog in stock today but Tom Kerrigan is sending his in for this and a very secret project stay tuned.

This is fantastic news! Very excited to hear more! Thank you for listening...

Good deal.

ShakySarge lever vs. my old worn out one. Nice.

Good deal. Glad it got there. Let me know how it performs!

A little bird might have whispered something. Exciting times ahead guys.

In the meantime, I will focus on adding the titanium reservoir, and starting some experimentation around further accurizing the barrel. It shoots near to 1 MOA now, but I think it cam be further improved with a small tweak. I am having some ideas regarding drilling shroud bottom side holes and bedding the barrel in through them. As I already have barrel supports in place, they will be the framework. I have already modified the plastic breech shroud to be removable before the stock, so that I can then loosen the barrel screws, and slide the barrel and shroud out as one piece.

With regard to the above, I am researching different epoxies or other filler/adhesive and am open to suggestions.

It looks good, and I like that it is smaller around the back bolt, so that even with longer linkage, it should clear the plastic breech cover. However, it won't close. The nub for the pin should be centered so that the lever can be used in right or left hand configuration. Here in this picture, I tried to put it on for left hand, and the pin hits the breech opening. I will flip it over to right hand and try again.

Don't waste your time what I have coming will fix all that need for bedding etc.

[PCPhack]

It hits using it right handed also. I think I can put a thin washer underneath the rear bolt to shift it up just enough to clear, as there is just a bit of play.

You always do that to me....lol. Thanks for warning me first this time though. I wasn't sure if the secret project was only the bottom half or also top/barrel half. Will all this retain the bullpup configuration? Ditching the shroud also? If so, custom cantilevered picatinny rail with tensioned barrel?

It's just like Christmas! Oh my!

Yes, Oldpro, please do keep us informed on these Bulldog mods.

Now I am wondering if my breech is not gapped at the rear like it should be. Time to inspect my dog and see what the issue is. Can the side of the front holes be filed a bit to make it clear the pin?

I solved it like this picture! One washer added.

All, this really is great. Before, I had to flex the aluminum handle back some to get the sear to lock up. Now it is just a smooth motion and it grabs the hammer really easy. Travis, I look forward to the machined solution you guys come up with, but in the meantime, thanks so much Matthew!

[PCPhack]

Only this issue remains. It's a little too long and hits the breech plastic cover near the gauge. This only prevents a tiny bit of the bolt retraction, so might not matter. I will probably just grind it down a little to clear the bump.
