Wondering what everyone's in put is on the different bases out their. dednutz, Talley for all in one base and rings set . Is one piece is better than two piece, I have all ways used 2 piece and had no problems. but i am putting a new scope on a rifle browning bar long trac and I,m looking to get the best accuracy out of an auto I can. The scopes i have in mind is swarovski av and kahles kx both in balistic retical. I have read about Koskins problem with kahles and legacy. Various post about swar scope having problems. wich one is better?

It may depend on what you're putting the bases on . Some bolt actions need 2 piece ... 1 piece interfere with the bolt action ... an/or ejection of spent cartridge . Ask the guys here ... no better experts in the world in my opinion ... but they need all the specs first . Which rifle --- which scope ... etc.

I like two piece bases and here's why.
In my effort to maintain optical center in my scope, I will set up a black target on a white background so when looking through the bore there is a small white edge around the black target to help get it centered in the bore, I do this at a distance of 29 yards. After I have bedded the bases with Devcon and dremeled out any exces in the base bolt holes, I will use the left right play created by the space between the base bolts and the holes through the bases. This allows me to get the scope lined up windage wise so I only use the turrets for fine tuning. I prefer to use Burris signature rings so that I can use the inserts to get the elavation where I want it. This is after I have lapped the front dovetail into the base so that it will turn with minimal resistance so as not to bind the scope tube when moving the rear base to the left or right to get my windage lined up.
Sometimes I can hit in the ten ring at 100 yds without adjusting the turrets, sometimes I have to bring home the shot target and realign the scope using it.
Hope that helps.

If you can, always use a 2 piece system!!...........Other than the scope over the receiver, there are no possible obstructions with a 2 piece, where as in some cases using the one piece which is and off to the left (if you`re a righty), MAY cause ejection issues.............Besides! The 2 piece system is cleaner looking and generally looks better!..Assuming there is enough scope tube length for mounting, try not to use off-setting rings either! Those IMO, are butt ugly!!!

You don't have to worry about the one piece bases on a BAR. The top of the receiver is closed. With a one piece base you don't need to worry about alignment on you BAR. Nice gun, BTW.
I am a big fan of Talley steel mounts, with the Warne's up next in vertical split rings. They are both very strong and well made. Reports on the Talley aluminum mounts have been positive here @ O.T., also. |

Flcooler, Devcon 10110 is an epoxy putty that is embedded with shavings of steel for added strength, it really is good stuff.
This is how I bed a base.
First I put two layers of Kiwi neutral shoe polish on the top of the reciever so the base will release from the reciever. I will also put two layers on the base bolts.
Next I will sand the underside of the base to scuff it for a better bond to the Devcon.
Next I will take a Dremel with a cutting wheel and cut some grooves on the underside of the base so that the Devcon will have something to grab on to.
Next after mixing the two part Devcon I will spread a small amount on all contact surfaces on the underside of the base.
Next I will bolt the bases to the reciever using about half of normal tightness when tightening the base bolts, this way you don't squeeze the Devcon to thin. I will do this while I have my very sensitive Starret pocket level resting on the top flat of the base so as to attach in a level orientation. Of course this is on a leveled action being held tightly in a padded gun vise.
After 24 hours I will remove the bases and dremel out any excess Devcon in the base bolt holes so as to create the play I talked about in my earlier post.
Bedding the bases creates that 100 percent contact between the gun and bases, which removes the possibility of your mounts creeping around. It is just like lapping your scope rings for that higher percentage contact.
There is probably not a whole lot of people that will go through all these steps to squeeze that tiny difference of accuracy out of their rifles. I just think if you are going to do it, go all the way.
I hope that helps.

flcooler, as far as your two scopes choices are concerned, both are excellent and you would probably be very hard pressed to see a difference between the two from an optical standpoint. As far as scope mounts are concerned, choose the mount that will allow you to obtain proper eye relief. I have never been able to discern a difference between a one piece or two piece base regarding accuracy. That theory went the way of the Buffalo many years ago as it should have. I can guaranty you that you will never obtain better accuracy with your rifle by using a one piece base or by "Devconing" it to your receiver.

there are theories on both side of the fench, but as mentioned above , what ever it takes to get proper cheek weld and eye relief. sometimes a one piece has extensions on one end or the other to help with this. the best bases are those that are part of the receiver, one piece, surgeon, gap templar,i-con and the new sako.

IMO
2 piece bases, front and rear are far superior to one piece.
Talleys are the best. I like to use the 2 piece permanent attachement kind. You just can't beat the fine machining of those Talleys and they are rock solid when you're finished.
Weaver style bases and rings are second but buy good ones like Warnes.
Dual dovetails are good if you get a good seal when you twist them in.
Redfield style with the windage screws on the rear base are only OK if you install them correctly and get the windage screws in exactly the right place and don't twist them off.
