Benchrest project completed, range report
- Thread starter cycbb486
- Start date
I have some time
now so here are the details.
The project is going to be a Light Varmint(10.5Lb) Benchrest gun for group shooting 100 and 200 yards. The caliber is the king of shortrange the 6PPC. The brass used is Lapua 220 Russian necked up to 6mm. The chamber size is going to be a .269 neck so brass will be neck turned to approx .2675 when loaded. The bullet of choice will be either Bart's 68gr Ultra's or Opel 66gr bullets. It would be nice if the Opel work out cause they are Canadian made.
Components of the build are:
Bat Machine action, right bolt, left port, right eject (one of the hottest at present)
SG&Y benchrest stock made by Robertson Composites
Jewell 2oz trigger
Bat Machine rings and trigger guard
Weaver 36x scope
Finally a 4 groove 13.5 twist Gaillard barrel finished around the 22" mark
I am using a Gaillard barrel as they appear to be one of the best bangs out there for the dollar. 350.00 CDN. It is a no hassle barrel that is made right here at home. No permits or dollar exchange required. Ted does shoot BR himself.
I do plan on one day trying a Kreiger or Hart. Kreiger at the present time appears to be the barrel of choice in this game. Time will tell if a Bartlein barrel will be worth a try. If memory serves me correct the fellows at Bartlein used to work at Kreiger so I would think they know how to turn out a great product. Time will tell if there machines will be able to do it.

Update on the build.............
Guntech has all the required components including the Gaillard 13.5 twist 4 groove barrel.
He informs me he will get at it next week.
It will easily make the 10.5 lb weight limit. We will actually end up adding some weight into the buttstock.
I thought the barrel contour was a bit on the light side but Guntech informs me that he feels that sometimes the LV's are to barrel heavy. I am putting my trust into the man with experience.
I asked Dennis what he thought of the Bat action and Robertson Composites stock. He is very impressed with the workmanship of the crew at BAT Machine. He also feels the stock is very well put together.
The 1 year wait is just about over.

I have the .269 (Jackie Schmidt) 6ppc reamer that I built a rig with 8 months or so ago. I've learned that I hate turning necks so it's a good thing that I don't have to go smaller than that.
Oh and it really shoots, especially if I get some more time to play with it. 68 Barts Ultra is what I've been shooting and I have a whole bunch left and no reason to change so far. Jam'em hard

gotta say, not my cup of tea, but I bet it'll shoot like a hot damn. the idea behind the two sided receiver is kind of neat. but do you lose any strength that way? I would think you are giving up something? although maybe it balances out the torque affect that a single sided receiver has under stress?

Just curious as to what you mean by that?

If I knew the
answer to that I would tell you.
Is there a strengh issue? Who knows. It is aftermarket made of high quality stainless or aluminium depending on which manufacturer one decides to go with. It is no off the shelf component. There is plenty of meat there. The idea of the dual port aids in speed. Sounds kinda funny for a single shot action but it is. The top shooters can single feed 5 rounds and send them down range when a condition is present in between 15-20 seconds. I am no speedster but I ordered what I wanted when I ordered the action. Mine loads from the left and ejects the spent out the right. All I know is that dual ports are used widely in Benchrest. The trend is to go with what is hot and working at the time.
The other aspect of the aftermarket action is the tighter tolerences in the bolt to receiver fit. There is not very much slop in this baby. Would not last a day out in a gopher patch. Would jam up B4 you knew it. It is built for one purpose chucking lead down range off of a rest and bag at paper. It is like a HotRod. Drive it when you want. Shine it up and look perty when you don't.
My Rem 700 6BR is now my field gun.

sorry to hear you have down with this disease
and I wish you the worst of luck to a non-speedy recovery.
nice rifle but the one- piece rest sucks.
glad you have come aboard and wish you well in developing a load. maybe get is shipped with the barrel off.
good luck jeff

Sorry man...........
all the money went into the gun and I can ill afford a real rest.
She is sent in one piece. It ended up as a glue in. There is plenty of insurance on it if Canada Post F---- this up. I have no vice yet or wrench. That is on the ordering list.
I may need more bullets so stay in contact.
How's the rail doing? Let's get some picks of it...........
I will steal your line,"if I can't shoot good, at least I can look good trying".
See yah,

I understand the reason behind the dual ports, and think it's a neat application. what I meant (this is for Bill) about the strength and torque issues is this. Most people admit that solid top receivers are stronger and therefore more capable of better accuracy, then open topped receivers. So now you take a closed top receiver and cut another slot in the side, obviously this is going to affect it's strength and such. But at the same time, having the two slots could help even things out harmonically and in relation to torque as it's more equal than just one slot on one side for feeding and ejecting. I figured maybe our new proud rifle dad might know. I am sure someone somewhere has some science on these new actions.
This action is fairly short and designed for small cartridges and the entire bottom is solid and quite substantial. The right port is very small compared to the left port. Really not much torque to worry about and it easily handles pressures in excess of 65,000 pounds. (Which are common in short range Benchrest loads in this calibre).
It has also been proven in the short range Centerfire Bench Rest field to be an extremely accurate action.

There is no doubt that the action is influenced by the removal of the material on the opposite side. I don't think anyone will argue that.
The influence in this application is negligible and insignificant for these rifles for their intended application. I haven't done any calculations but base this entirely on down range performance in the sport. The benefit of speed of the second port far outweighs the "worry." Down range results are the proof.
Pure torsion is minimal. The bending moment caused by the barrel weight is the one I believe you are concerned with.
I am sure that when compared to a Remington the Bat is substantially stiffer.
Given that no one seems to believe that a blue printed Remington is any less accurate than a custom action I would suggest that any increased stiffness over the "Remington standard" to be of little practical use.
Very very nice toy cycbb486!
Nice to see all of the Canadian content.

There are also drop port actions made by Stiller (maybe others as well?). There is a case size cut in the bottom of the action and the empties drop down and are funneled out the bottom of the stock into a box below. The size is such that a live round won't drop through.
