Time to copy Boomer

Since I first caught a glimpse of boomers custom 602 I was in love. Although I am going to do things a little differently I will be essentially making the same thing, a serious workin' mans protection rifle. I could always go out and get a 375 booger, but nothing spells class light a magnum length square bridged mauser. I have aquired a BRNO 602 action and a high quality fiberglass stock. It will be a .375 bore and wear a 20-21'' chrome moly tube, with a NECG banded front sight (complete with brass faced straight blade), barrel band sling swivel (I have always loved the looks and rarely, if ever, shoot with the aid of a sling) and an NECG peep sight on the rear base. I have some warne QD rings and a VxIII 1.5-5 x 20mm in case I want to go hunting with it or need the reach. I will also be changing out the trigger. Anybody know any quality triggers for the BRNO with a SMOOTHE face? I can't stand serrated triggers. Now all I need to choose is the caliber. Might as well fill up the action so it is limited to these few (please pipe in if I have forgotten any).

- 375 H&H (because...well just because)

- 375 H&H Ackley Improved (I am not really interested in the meager performance gains of the AI version, rather the increase in brass life. I have not gotten a definitive answer on the subject but it makes sense to me that a straigher case with a sharper shoulder should last longer.)

- 375 weatherby (for reasons stated above)

- 375 RUM (for its versatility and brass life)

The 378 weatherby is NOT an option, expensive brass and higher velocity than I want or need.

What do you think? any suggestions?

Slimbo I am doing sorta something with mine, along the lines of what you are doing, but I am not copying Boomer, my aim is to make the rifle into a serious bear and moose gun..

I have ordered a McMillan CZ Express stock; placed the order today. I think I asked for the molded colors black, grey and brown...

I have ordered a Talley barrel band from Brownell's, plus a Timney trigger. The Timney is supposed to fit a CZ-550 and so I don't actually know that it will work with the ZKK-602 but I'm hoping it can work.

My rifle has the Warne matte, medium height permanent rings with a 1.75-6x Vari-X III on it. I will not be changing that, unless maybe to throw a 1.5-5x Vari-X III on it, and might only be if I wanted the 1.75-6x on something else.. It wears the 1.75-6x scope very well.

I need to get the barrel band installed, hopefully David Henry or K&S Arms, but only if Karl is gonna do the work, and so hopefully I will have the Timney trigger by then, in case there needs to be anything tricky as far as the install goes.

I see no need to do any fancy stuff with the barrel, I will keep the ass-backwards 2-pos safety.




Edit: Oh yeah, mine is in .416Rem caliber.

Well obviously if you are going to be following Boomers lead you have no choice but to go with the 375RUM... :D

Being that I also have a 375RUM and know how versitile it is there isn't another 375 round that I would look at.

Being able to shoot heavy for caliber loads like Boomers or loads that can reach out with authority is a major bonus too me.

I am not planning on building a rifle but am considering shortening my Rem 700 LSS's barrel by a couple inches from 26" down to 23" - 24" and installing a front sight with quick detachable rings so I can install an XS Sights Backup Ghost Ring rear sight if I am venturing into thick bush after another grizzly.

I install Kick-Eez Magnum recoil pads on my heavy recoiling firearms that reduces felt recoil more than any other pad on the market I would totally recommend that you check them out.

Good luck on you build hope it works out for you... :wave:
 
I was told that it is a mcmillan but I cant find any markings on it. It seems to be fairly high qualitly though.

Oh, so you acquired the rifle action and stock as we see it?

What are you going to be hunting with it? Mainly grizzly defense I imagine, eh?

I think anything from a .35Whelen, .375H&H, .416RM would be fine. Of course I would stick with more traditional cartridges, but that's just me.

What's the deal as far as knocking a few inches off the barrel? I have considered that with my .416RM but I don't know the legalities? Is there any issue there or can I just get it modded however I want? :confused:

I think something around 22" would be nice...
I could get that done the same time the barrel band is installed.

if you cut your barrel down below 22" you'll go to jail

Why is that? I thought 18.5" was minimum.

If I did get it cut down, it would not be a lot. Maybe 22" to 23.5". It seems that most guys that cut down the 25" Brno barrel go for something like that range.

It's just a thought. Besides, to install the barrel band the front sight has to come off anyway. Chopping the barrel, might make the gunsmiths job simpler.

My 700 375/338 feels perfect with a 21" bbl.

I handled Crazy Davey's 550 with 20" bbl and it was vastly improved over the front heavy 25" version.

I think the RUM gives you just a little more versatility over the H&H, although that versatility might not be realized with normal weight bullets. The RUM offers affordable brass, that is something that cannot be said of the other high volume .375's, and I consider the absence of a belt to be an advantage. The Rum has a rebated rim, so you will have to ensure that the top round in the magazine is as far forward as possible, or the bolt might fail to pick it up. At recoil, all subsequent rounds will be against the front of the magazine.

It's difficult to tell from your pic how much drop the stock has, and this drop becomes important if you plan to do much shooting with irons. If the stock does not have enough drop, you might find that your head is snapped back painfully if your cheek has to be squashed onto the comb to get a sight picture.

I'm not a fan of the Brno set trigger, so I opted for their single stage trigger, however it is grooved. If you can't find anything else perhaps you could polish out the grooves.

Looks like you're going to have a fine rifle when the dust settles.
 
A fine project! Excellent action choice.

Now, for my preference if you want to move away from the excellent .375 HH - even tho i see no reason to - I would opt for the Ackley version. I have found that with 300 gr Sierras, with no visible pressure signs and brass that mic out fine, I can get 2900 ft/s into a very small group with my Sako Fiberclass.

The brass is very plentiful, you can still shoot .375 HH in a pinch and you get all the benefits of a not so meager increase.

I find that with most of choices you listed -- there is sufficient velocity and energy for most any job, the trick is to predict where your bullet will fall and that a good scope with a reticle like TDS or Boone and Crocket and practice will allow you to easily compensate for a few inches more drop with a milder round.

Nothing against the RUM or any others, the HH / Improved will reach very similar speeds with the fexibility if you need it for standard ammo.

The extra cost for AI or Weatherby dies would buy alot of standard H&H brass and make the actual savings with longer brass life moot.

I'd go standard H&H.

farshot hard to disagree with anything you stated extra performance as well as being able to shoot factory H&H good combo except for one issue that I have.

I'm thinking resale value not that you would ever sell this rifle after it is finished. ;)

I feel that wildcats have less of a demand when you are looking at selling a rifle due to there not being as big of a group of potential purchasers compared to those that want standard factory available rifle/cartridge combo's?

With that train of thought I guess I would have to look at others wanting readily available rounds and the H&H is definately the most readily available round.

When I see the amazing performance/versatility difference between an H&H/Ruger and the higher velocity rounds that are available I will never go back to the H&H...

Dont want to hijack the tread, but for the amount of powder difference with the rums, i dont think it gains you a whole bunch more performance. Again, no issues witht he rums - i do like them in their own way.

If I was leaving the country to hunt with a .375 - it would be the AI / HH as ammo luggage has the habit of going sideways and you may be left with a rifle that you cannot get ammo for - but that is a specialized use or reason for sure.


And your contention of re-sale value is probably correct,........ if you assume one ever sells his rifles.
