Blaser R8 In Large Calibers

With the R8’s it’s mostly stock type one prefers, magnum vs non-magnum bolt head though those can be swapped out. You can only get above a 375 H&H with the traditional type stocks, not the thumb hole style. The rifle is designed to be modular but there are some limitations. There are quite a few barrel options available as well.

I have a Professional Success and Ultimate, both of which are thumb hole. You can get a .375 RUM in these, which is a vicious round. My .375 has worked well on a variety of DG with the thumb hole stocks. Unless you're hunting elephant, a .375 in H&H, Ruger, Blaser or RUM is all you need.

You can get a custom barrel in any caliber and other customization imaginable. A 28" barrel, needed for ultra high velocity rounds, works great in these stocks.

For the bigger calibers, .416 and above, you need the traditional safari stock.
 
The interchangeability, take down, etc are all nice but I haven’t seen mentioned my favorite feature: the action length. Due to the design, it is a few inches shorter than a usual rifle and that not only saves a few inches, it changes the balance. I find my R8 to be the easiest-handling rifle I own. Part is the weight- I have the aluminum receiver, synthetic stock, standard barrel 375 so it’s pretty light for what it is- but it is also how it is distributed.
 
Question for the couple of guys that have custom 404 Jeffery barrels for their R8. What magazine insert are you using? Also it’s been confirmed in another post that the ultra magnum bolt head definitely works, but heard speculation elsewhere that a normal magnum works fine as well. Anyone know if that is true?

You are exactly correct. On of the attributes often touted for single shots like the No 1. I use the exact same set-up as you, and the rifle is perfectly balanced between the hands.

You might try this insert:

This is interesting to me this discussion of an ultra mag and mag bolthead being a different thing. See below table from the Blaser website.

Just how many bolt heads are there actually? Is there any difference in the Magnum and Ultra Magnum bolt heads?

Are we going to be disappointed if we could take calipers to these different bolt heads and find out they aren't so different after all? Which granted probably won't happen easily since the parts are so expensive and a dealer sure wouldn't want that to get out if there is no difference aside from markings. I have already seen that the Lapua bolt head is just a Jeffrey bolt head struck out and relabeled at least in one instance.

Anyone with a Lapua care to comment?

I was actually thinking about this very question the other day of just which bolt head would a .404 user want to use for a Jeffrey build.
 
I believe @Red Leg mentioned something about this one time before.
For the life of me I can't remember what he said.

For the R8 (in the US) the ATF considers the stock the "gun" portion of the puzzle.
However the barrels also have a serial number.
All of these must be listed on your CBP4457 for re-entry into the US.
Along with the serial numbers of your scopes and binos.
Why in the world would the serial for my binoculars need to be on a 4457?

It's to prove that you didn't purchase a high priced item out of the country so it's not subject to any import tariff or tax. In truth, the 4457 is only for the US Customs although foreign country officials do look at it. This form is to prove you are only bringing back into the country with what you left with.

Truthfully, I know several people who don't do this and have been to Africa and other places around the world without a problem. However, the trouble of adding on the serial number of my binos and scopes is easier than having to possibly deal with a Customs agent who's had a bad day and feels like busting my chops. Call it a "belt and suspenders" approach. Your choice.

Which stock do you prefer for regular use? And why? I have the ultimate (thumbhole) stock and really like it. I prefer it over my kids’ professional stocks. (Not asking about aesthetics, the wood stock should be named Jealous rather than selous.)
 
I have Blasers with all 3 Stocks. For DG and BG there is nothing better than a normal Stock (super fast ready to shoot). If u have time and need to get long precise shot i prefer the Ultimate stock.

This is my favourite gun, ultra light shoots 1/4 moa out of the box

I'm unfortunately on a diet. Presently in VA hospital as Agent Orange finally caught up with me. Cancer and I no longer can speak. If all goes well I'll be out of here and back home in Thailand by end of July. Tough road but I'm a tough old guy. I'll make it that hunt.

Nice one there. I guided for mulies and elk for about 10 or so years in northern New Mexico.
