I am wanting to build a 416 Taylor on a Remington 700 action, it is a 7mm Mag at the present and I am wanting to build a big bore, any suggestions

Build a .458 Win Mag instead. There are many more bullet choices available in .458, including hardcast.

GeorgeS...
thanks for the reply, but I already have a 375 HH and a 458 Win Mag. I was looking at something in the middle.

There is the 416 Ruger. More power than Taylor and is a factory chambering. The 700 action should also handle the 404J as well as the 416Rem Mag.

416 ruger .. just buy one .. or build on a rem .. factory brass, dies chamber, and in a pinch, ammo

oh, and its a larger case, with REAL load data

The 416 Taylor would be an easy conversion, you would only need a 22" long barrel.

We (as a group) worked together and built a 416 Taylor for MADDOG when someone (inside information) stole all of his rifles. He has been pretty happy with it.

Brass is super easy to make from .458 Win Mag brass. I hear good things about RCBS and Redding dies.

Do what you want, Have fun with it.

Should need just a new barrel. Made three 416 Taylor's from CZ 550's in 7mm Rem Mag. Maybe some tweaking of the feed ramp but maybe not too!

It is relatively easy to make brass from 458 WM cases and a 416 Taylor die, which are pretty common these days.

Lots of 416 bullets around.

It ain't a 458 WM but then neither is the recoil!

I really like the Taylor. Have been playing with one for the last few months now. A couple things regarding this cartridge:
Do not use brass from quality cartridge company with the .416 Taylor head stamp, it will lock up the bolt with ANY load. Even a 1,800 fps load. Something wrong with the location of the belt. Same to a lesser degree with Superior brass.
Use only Winchester .458 WM brass.
Next; grab a can of RL-15, and IMR 4895 for your load developement.

It's a nice cartridge!

I am using the Quality headstamp brass in my 416 Taylor and have no problems such as you describe. Not saying it doesn't happen just not in my rifle which is on a VZ 24 action.

Hope some others can fill in the blanks as the brass is too expensive to waste.

Did you send it back in to have it checked?

Having said this I also use the 458 WM and like it a lot in the Taylor.

No, have not sent it back, the owner has had the brass for some time, and had it mixed in with Win. brass. he noted that the bolt was pretty stiff at times and thought it was fro m his loading being too hot. I sorted it out and discovered it happened only with the Superior brass. So we ordered some quality cart. brass with the .416 Taylor stamp. Even light loadings took 3 hits with the hand to get the bolt open, every time.
Bought new Win. brass and problem solved.
Glad it works for you though. Wish we could get some properly head stamped brass that works in this rifle. It's a Win. model 70 custom built by the late 'Larry Brace'. The rifle and chamber are flawless. Had the chamber re-checked with a casting by another good smith. He said the chamber was flawless. Wondered if the make up in the brass could be different and possibly does not spring back enough after firing. A real head scratcher!

On a Rem. action why not go Rem Mag. No difference in work required and a good step up.

I built a 416 Taylor on a Ruger 77 Tang LA action, BEFORE the 416 Ruger came out. I like it very much but today I would chamber the 416 Ruger for all the reasons already mentioned.

They are identical for all intents and purposes as far as game killing goes, the Ruger has 6-8 gr more H20 case capacity, but I think the Ruger case sits in the mag and feeds a bit better...no "monkeybumps".

Of course the words...416 Taylor...brings visions of the Dark Continent quicker than 416 Ruger...but that's a matter of opinion.

Doing either conversion on a Rem action is a piece of cake...just a barrel change...you can even keep the 7RM barrel as a "switch" barrel, just in case.

Be carefull when you chamber if you go with the belted case. Pick out which brand of case you want to use, measure the belt then use one case as a guage to headspace on. This being a wildcat you can do that.

I have found belts measuring 0.200 to 0.230" on different brands of cases. I have mine set up for Rem cases at 0.215".

For the Ruger, resize a case in the sizing die you would use and give an additional 0.005" for clearance so you don't resize too much and the cases last longer, but check factory ammo shoulder to base dimensions and be sure you have clearance. Most of the time(but not always) factory ammo is short just to chamber in all different brands of rifles.

I use Stoney/Hornady headspace guages to do the measuring.

Bolt lockup "usually" relates to pressure problems...doesn't matter if it is a "light" load according to some reloading manual or not. Could be neck walls too thick for the chamber neck, bullet being seated hard into the lands because of a "custom" chamber or too soft brass, or headspace problems due to sizing.

When your type of problems crop up I fall back break out the micrometer, calipers and headspace guages and start with fresh brass...forget the headstamp until the problems are sorted and identified.

Enjoy which ever one you do.

Luck

I have built a couple of .416 Taylor's. I like the Taylor over the other 416's because it will do what needs to be done without a lot of recoil. I finded it accurate and deadly at long range and a stopper up close. It's a great all round cartridge, especially if you want something a little bigger than a .375 H&H. A 22" barrel is all you need. I built mine on a PF Win. action, it has 4-in-the-floor and weighs about 8.5 lbs. with an Accurate Innovations stock. Recoil on the bench is manageable and light in the field. I also had problems with cases sticking from Jameson. They knew there was a problem and sent me a sample to try, they stuck. All brass I made from Win. and Rem. .458 brass worked just fine.

It's a great cartridge, you won't be disapointed........Tom

I want to take the time and say "Thank You", to all that have replied. I made my up to build the 416 taylor with a 24 inch barrel. I will build my own stalk to fit me and it will probably tip the scales at around 10.5 lbs. I am going to use a 2-7 power scope for all purpose shooting across the field. It should be a fine setup for cast buillets if I can find a mold that I like, once again thanks to all.

Jebb45, Beartooth bullets makes a 335GC that my Taylor seems to really like. Marshall Stanton is the owner and knows a great deal a/b cast and getting them to shoot. His info helped me.
I think you will really like the Taylor. It's big fun, but not punishing. Good luck.
