Scope Rosin

[billt]

I discovered something I'd thought I would share. I was concerned about scope movement on my new .50 cal. Bushmaster when a fellow shooter on one of the fifty caliber shooting forums suggested this product.

I bought some and applied it to the inside of the rings. It is a tacky yellow powder that is very similar to the type gymnasts use to keep their hands from slipping off parallel bars, etc. I used a small model airplane brush to apply it dry, right from the container.

I had a scope move slightly on my new Savage Model 110 FCP-K in .300 Win. Mag. when I took it to the range last week. I pulled the ring caps, cleaned everything with denatured alcohol, applied the Rosin and reset the scope, and torqued everything down nice and tight. The next day I went back to the range, and after firing almost 60 full power rounds, there was zero movement. This is one of those inexpensive products that works really well that not many people know about. From now on I'll never mount a scope without it. Bill T.

One of my buddies uses the stuff and is very satisfied. Another uses Loc-tite (can't recall which flavor) and says that also performs well.

Thanks!

I only use Loc-Tite on scope bases, never on the rings. In fact I do just the opposite on rings. I oil the threads on the ring cap screws. This allows for the transfer of more torque to the ring caps themselves, by allowing the transfer of the torque directly to the caps instead of being diminished by the screws themselves. Bill T.

My gunsmith uses rosin on the rings for the same reason. I don't have anything that kicks so bad that it moves the scope. That said, I usually torque the screws down tight enough to break or at least bend the allen wrench.

Rosin is really needed on Magnum rifles with muzzle brakes. Muzzle braked rifles are very hard on scopes because they have a unique recoil effect, much like that of an air rifle. .50 BMG guns are the worst because their brakes are so effective.

When a rifle with a brake is fired the gun starts recoiling rearward. This is Issac Newton, and nothing will stop it. Then, a millisecond later when the bullet passes through the brake, the hot gasses driving it hit the ports in the brake and begin pulling the rifle forward, much like the clam shell thrust reverser on a jet engine pulls the plane rearward. You as the shooter don't feel this. You simply feel the soft push the muzzle brake makes happen. But the scope feels everything. First a rearward jolt at about 400 G's, then a forward jolt at about the same G force. It's a bit like hitting a concrete wall in your car, then getting rear ended a millisecond later. Your neck would get whipped like a wet noodle. This is the same effect a muzzle brake puts on your scope. The better the brake works, and the bigger the gun, the worse it gets. This is why Rosin helps so much in aiding the gripping force of the rings. Bill T.

that stuff might be corrosive as well... if you have good rings no need for that crap...

Rosin is totally non corrosive. Talk to some dedicated .50 BMG shooters. They'll give you a fast education about scope rings.

If you can find them beefier than this, please let me know and I'll buy them. Bill T.

what kind of rings are those on your rifle? badger? Do they have recoil lugs so that they don't slip on the picatinny rail? try the talley tactical rings, buy them from me and if you don't like them better than the ones you have then send them back for full refund... you have nothing to lose... order online at the link below...

The rings are made by Smith Enterprises. They have not one, but two recoil screws running through the base of the rings. They are wire EDM'd out of solid 4140 steel. Smith Enterprises specializes in products for the .50 BMG shooters.

I'm sure Talley Rings are of very high quality, but .50 BMG Shooting requires a specialized type of equipment above and beyond what most Magnum rifles require. Even with a dozen screws to tighten the rings, and a total of 4 cross bolts to attach them, scopes still move in .50 caliber shooting, hence the need for Scope Rosin. Bill T.

Bill the talley tactical rings come in a 6 screw version as well.... like I said try the talleys and if you don't like them better... .... doesn't cost you one red cent... see my msg above...

[Bushman]

Swamp, I put a set of Talley's on my Cooper an they were the easiest scope installation that I have ever done. Good stuff.

I've got a nearly new set of Talley rimfire rings in my junk box. Bought them for my Marlin 995 semi-auto and they won't hold on the dovetail no matter how tight you reef them down{scope walks on the dovetail rail with recoil}. Went back to the cheap {6.99 a pair} old Bushnell aluminum rings. The Bushy's aren't nearly as good looking as the Talley's but they hold like a pit bull. The Talley's are worthless to me.

Sabre, Talley doesn't make rings or mounts made to fit the Marlin 995 dovetail no wonder they don't hold to that Marlin 995 dovetail...

Lots of custom gun makers like Dave Tooley, Jim Borden, and Kenny Jarrett use by Talley's... www.jarrettrifles.com/scopes.html

I think the rings I have are the standard Talley RFRL {rimfire low} rings that are not made for a specific model. They are machined to fit a standard, flat topped 3/8" dovetail and should work on my Marlin as it has a perfectly standard, flat topped 3/8" dovetail.

here is a summary listing..

do you see any numbers engraved on the bottom or sides of those rings?

[Sabre]

I don't see any numbers on them anywhere. They have "Talley" imprinted on the side down at the base and that's it.

[swamp]

for the marlin model 995 you need talley part number 22M882

Thank's but no thank's Swamp, I'm done messin' with Talley's. Don't want a base and ring setup on there anyway. The Bushnell rings haven't moved one tiny bit in two years and 5000 rounds and I don't expect they ever will. No point fixin' what ain't broke.

[swamp]

Talley 22M882 are rings only... not a base/ring set up

The Talley RFRL rings are for .500 inch dovetails...

Well then the rings I have aren't the RFRL's. As I said before the rings I have are machined to fit a standard, flat topped 3/8 dovetail. The description for item # 22M882 says it's bases only and designed for Talley's QD or fixed steel rings.
