M40 SWS (Win 70 action)

This is an old video I did with my Autofocus webcam to show off the work I did on my rifle. Everything was done by me except for reaming the chamber and fitting the McMillan barrel.

The Winchester Model 70 "Classic" short action is pillar bedded in a McMillan fiberglass M-40 "HTG" stock in 3 color desert camouflage. It is chambered in .308 caliber. The action is pillar bedded but the barrel is not supported. This was done to determine if the bedding was stable enough for long term use. The sling swivels have been mounted into aluminium blocks which were epoxied into the stock. This ensures a solid mounting point with no chance of tearing loose. The cheekpiece was cut by hand and epoxied to the handmade adjustment mechanism, which was fiberglassed into the buttstock. The adjustable buttplate was manufactured by David Tubb and sourced from Brownells.com. It is adjustable for drop, angle, and length, but because the recoil tube is threaded and locked in place by the clamping mechanism, it is recoil proof. The scope mount was manufactured by MWG, and is bedded onto the receiver with epoxy. The scope Is a leupold Mk4 M-3 6x. It has a 30mm tube and a 40mm objective. The factory trigger was polished and the spring has been replaced with one that's longer and lighter. The trigger breaks at exactly 4lbs which is the minimum for a field rifle. The barrel is a McMillian "Marine corps" 1-12" twist barrel that tapers from 1.25 at the breach to 1" at the muzzle and has been cryo treated to relieve any manufacturing stresses. The Iron sights on this rifle consist of a Redfield "International" rear sight and a Redfield "Palma" front sight. The "Classic" receiver is not drilled and tapped for a rear target sight so this was done, the base was then bedded in epoxy to ensure zero movement of the sight.

man.. thats a sweet rifle! i wish i had one like that. the only question i have is why does your camo have a glare? you did a great job with the break up pattern. i treid to do a digital pattern on my svage .22 and it looks like a jigsaw puzzle. your is more simple lookin and still looks better.

@MrThepipelayer1 The Camo is molded into the stock by McMillan. It's about a 1/8 deep into the topcoat so that if the stock gets dented or scratched the color won't be affected.

The paint on the scope is epoxy spray grit used for concrete steps.

The glare is from the smooth finish of the stock, not the paint itself.

BTW, I had to redo the scope about 4 times before I got it to match the stock... Practice makes perfect.

do you void the mcmillan warranty for cutting their stock ?

[Whitehorze]

@scktz Yes.

[Australianhunter]

what is twist exactly mean? can some one tell how does it effect bullet path and etc, your answer will help alot thanks

[Whitehorze]

@Australianhunter Because .308 bullets can range in weight from 110 grains to 220 grains, I needed to match the twist rate of the barrel to the range of bullet weight I intended to use ( 190 gr ). The american military normally uses 168 gr match bullets in it's sniper loads so they select rifles barrels with a 1-12 or 1-11 twist.

If the bullet is over spun by a fast twist barrel it can come apart, if it isn't spun enough by a slow twist barrel, it won't be accurate due to tumbling.
