Randy…thanks for taking my questions! I shoot the Remington 11-87 Special Purpose Deer gun with 2 3/4″ 1900fps Remington core lock Ultra (385 grain) slugs. I sight in with an Otters bench rest, however am not getting as good results as I would like. I can group a couple of shots then a “flyer or 2” then it comes back into center, then another “flyer”. This worries me because I never know when the “flyer” may rear its ugly head. Have experienced it in the field with drastic consequences. Any suggestions or recommendations?
Your accuracy problem you’re describing is more common than you may think.
I can only assume what is going on because I would need the actual barrel to verify my conclusion.
The barrel is gripping the sabot because of the rifling cutting into it but with a slightly bigger bore there is not enough pressure generated by the smooth inside of the sabot to grip a copper bullet that is being used by other manufactures.
The sabot MUST grip the copper bullet and accelerate it up to nearly 50,000 rpms within a 1/2 inch of forward movement down the barrel to make it fly stable and accurate with a 1-28 twist barrel.
This is a common problem with any make of sabot ammo using any kind of projectile that has some type of copper coating (copper washed, copper jacket, or solid copper)
No matter what manufactures makes it.
Lightfield patent guarantees the sabot and slug are mechanically locked together assuring the proper rpms to stabilize. The designs also include the ability of the pure lead slug to swell up (upset) itself to fill inside diameter of your barrel regardless of its size! The barrel itself sizes the bullet to the proper fit so each and every slug is a custom fit to the barrel firing the round.
If your slug gun won’t shoot groups with the Lightfield Hybred series of sabot, there is something wrong with the gun, scope, mounts, etc.
Some guns may shoot 1-hole groups, some may shoot 2-4 inch groups, “BUT THEY WILL BE GROUPS”, no crazy flyers way out of the group if you’re doing your part!
