Reloading 416 Remington Magnum

[4fifty8]

• custom Zastava LKM70 full stock carbine 20" barrel
• 340gr Woodleigh, 350gr TTSX & 340gr CEB V15 using Re15
• 100 yd POI approximately same for all 3 bullets
• was sighted in under very low winter temperature
• today 10 C checked zero surprising corrected POI 3 inches left = low temp effects??
• also reduced load using fast burn rate powder & Hornady 400gr RN improvise aim ok at close range

It's hammer time!

Very cool rifle. I also love the weatherby stuff.

I'd like to hear more about the rifle! Zastava with a Sako barrel? What caliber did the action start out with and did the ejection port and mag well need modifications to fit the 416RM rounds?

Beautiful build and great shooting.

375 H&H re-barreled to 416 RM no other mod's required except proper bedding to even out recoil force to prevent stock breakage. Jeweled bolt nice touch.

I used to use H4895 in my 416 Rem w/ Speer 350gr MagTip, around 2600 fps 24" brl, and RL15 under the 400gr Hornady RNSP for around 2400. Too much recoil for me! It killed, but no real difference over a smaller caliber on north american game

 

[4fifty8]

Conversion simplified 375 H&H and 416 RM both 3.600" max COAL.

340gr Woodleigh@2450 fps mv re-checked zero today - it's fine.

 

[Big bore dinosaur]

Nice shootin, sir

 

[4fifty8]

Improvised aim reduced load 400gr RN@1875 fps mv groups not too bad.

Nice to see someone spending time ringing out a real boomer. Big guns are sure fun.

41 caliber PPB

***For information only NOT a recommendation don't try this at home or elsewhere***

• paper patched 41 cal pistol bullets for use in my .416 Rem Mag
• using Blue Dot relatively low pressure load
• Hornady 210gr .410" dia. paper patch bumps up bullet dia. to ~.414"
• .414" dia. bullet in .408" bore dia. / .416" groove dia. barrel
• seems with patch under-sized bullet grips rifling better for improved rotational stability? no keyholers
• low cost plinking round 10 shot accuracy @ 100m not that bad

 

[4fifty8]

Berry's 41 cal 210gr plated bullets

• paper-patch for plinking 28 cents per bullet way cheaper than jacketed
• no keyholers Blue Dot works ok as with jacketed
• tried Herco maybe could vary charge to tighten groups

(NOT a recommendation)

Great post. Very interesting results with the 210g. I noticed the stock was bedded by the front receiver ring. Was the bedding compound applied over the steel crossbolt in the stock?

 

[4fifty8]

Thanks not exactly sure about that left it up to the smith to do seems to have done good no cracks.

 

[Evanguy]

Those stocks hold up well. Even unbeded they will hold up when chambered in 460 weatherby without cracking although it's only been about 100 rounds so far.

 

[4fifty8]

With an effective muzzle brake these big boomers don't kick hard at all my .416 Weatherby with full on loads recoils likes a .308 no worries cracking my Mark 5 stock.

Nice to see someone spending time ringing out a real boomer. Big guns are sure fun.

I just took a step in the direction of a bigger calibre; 9.3 X 62. Not quite in the same league. I am currently running 54gr of D4895ssc behind a 285gr PPU JRNSP bullet. Two shots, and I ordered a recoil pad, much sharper recoil than I anticipated. LOL. The 9.3 x 62 is sitting beside a 6.5 x 55 for reference:

Good to know. Is the 460 also built on the same action or a MK V?

 

[Evanguy]

Same action. It was a 458 winmag Zastava LKM70 that imade a bigger mag box, opened the receiver up in the front a little and a lot in the back and rechambered the barrel to 460. Its just the factory stock.
