Who made this synthetic stock for RSM .458 Lott ???

[Riflecrank]

One knowledgeable fellow thinks it is an old High Tech stock from circa 2006, after Bansner sold the name to another maker.
I called Bansner, he never made an RSM stock but subsequent maker might have ?
Circa 2006 was first year the .458 Lott Ruger M77 RSM was made, as was this rifle,
a Gen 3 with 23" barrel length and 0.750" muzzle diameter.
I collected this rifle from a local Cabela's Gun Library and they reveal nothing about the former owner ID for me to contact and quiz.

The stock is pretty light, 1 # 15.8 oz. even with the RSM steel recoil cantilever plate permanently embedded in it.
Assembled, unloaded rifle as above weighs 8 # 14.2 oz.

Excuse me for owning this .458 Lott, but I am sort of a redneck Buckstix,
with beer tastes on a beer budget.

Internals, same method of RSM glass bedding as Wayne at AHR used on walnut.
The "recoil plate" that falls off the barreled action is embedded solidly into the stock.
Wayne's job was much prettier with brown epoxy partially covering the steel in walnut.
Charcoal grey epoxy over carbon fiber cannot hold a candle to that, even it had been done as neatly.
That recoil plate is the only recoil stop, connected by cantilever to the bolster knob under the receiver.
I think the stock is 100% carbon fiber besides the steel recoil plate, epoxy bedding and paint.
Paint job is first clue to High Tech, according to my consultant ...

Second clue is charcoal-colored interior:

That skinny web between magazine well and trigger well is not cracked. It must be carbon fiber.

Wait, what….my eyes are deceiving me, you bought a 458 Lott! Rejoined the ranks of us Lottites. Very sturdy looking stock. Excellent find at Cabelas, this rifle looks to be indestructible.

Check out MG Arms in Houston (Spring), TX. I see shades of their stock in the pictures.

Maybe you can weld some steel back into the chamber and make it a 458 Win Mag. lol!
Have you measured the throat on it yet?

BJH65,
I was a sucker for the SAAMI throat to be measured, as TOBY458 questions, see below.
That and no doubt about it, the .458 Lott of any throating is a better firearm for loading with bird shot.
A better short-range pest gun, for rat killin'.
I appreciate your confidence in its durability.

RR 314,
Thanks for that. Yes, very similar, and they have been at it since the previous century.
Here is their "South Texas Camo": Epoxy paint and air brush ?

I will call them and ask if they ever did any RSM stocks.

I also need to call the current owner of HT Customs and ask if he is the guy who made High Tech stocks after Bansner sold that stock name.
Here is a bona fide High Tech stock from post-Bansner days on a Mauser belonging to a trusty member:

TOBY458,
I have to keep at least one curio .458 Lott with unaltered, factory chamber for posterity.
Thanks for asking about the throat measurement.
Using the SAM TOOL .458-caliber throat gage graciously fabricated and donated by Sam (you know who) ...

I measured this RSM .458 Lott for TETL (Total Effective Throat Length) aka "Slug Jump":
0.262"
Compare this to a calculated minimum of 0.2143" for the SAAMI .458 Lott.
Only about 0.048" length of slop, +tolerance.
Some of that might be due to the Ruger factory .458 Lott having groove diameter closer to 0.459" than 0.458".
It is a 1:14" twist, SAAMI "optional" to the 1:10" twist spec.

However, I have a .458 WIN MAG chambered SAAMI by McGowen, and their groove diameter is closer to .458" minimum spec, 1:14" spec Twist.
But SAM TOOL shows it to have +0.050" of throat length slop too: 0.6725" + 0.050"
or about 0.723" as best I can measure that TETL/SlugJump.

Such slop might be found in mass-produced/factory rifles,
maybe done with a new factory reamer made a little plus so it would wear into minimum before needing replacement too soon ?
Just picking fly poop out of the pepper here.

I say go load up some ammo and see how it shoots. I’m sure it will do all that needs doing with a 458 of any variety.
