My Whitworth liked the following load.

Barnes Manual Max. for 270 grain TSX? - Anybody?

Hi,

I just picked up a box of Barnes 270 grain TSX bullets to load in the .375 H&H. Does anyone here have a Barnes manual (I can't find one to buy locally)? I'd like to know what they recommend as a Max. charge of H4350 for use with this bullet.

Thanks for any help you can offer - Jeff.

Try this :

80gr H4350
Fed 215 Primer

Start at 77grs and work up to be safe.

Gibbs,

Here's one of how it looks now...

A close up of the Limbsaver "prefit" pad...

With the Leupold 2-7 Compact in place...

And one of the "Magnaporting defeat" attempt. It is high strength "epoxy" heatshrink...we'll see if it "holds"...:rolleyes:

I'm impressed on the fit of the new pad. Looks good!! The Pre-fit Decelerators didn't used to fit that well.

I hope you put some oil or white grease under the heat shrink. It probably will hold moisture and pit nicely if given a chance.

To defeat the magnaporting...

I have heard of a concept. Don't know if it work or not..

You turn down the end of the barre a bit, and then solder on a 'collar' then reblue.

It should work, in theory. Cost more than the heat shrnk, though. :p
 
I did clean and lube the outside of the barrel before "shrinking on"...thanks for the comments and suggestions guys. :)

The whole idea here is as a temporary measure for experimentation - just to see what the rifle is like without the Magnaporting. If it seems worthwhile, then I plan to figure out a permanent, removable sleeve that I can use when hunting and remove on for range use.

Jeff.

Take it to a gunsmith and get a screw on cap to hide the magnaport. Or have him shorten the barrel to get rid of it.

The .375 H&H has minimal recoil and does not need porting... not that any rifle does...

Care to sit down behind my 416 rigby that is not ported or braked and touch a few off the bench??? Guaranteed a couple of em and you will want to quit for the day...:D

Levi,

I don't think it'll be too bad...I've used this at work on Electronic cabling and it usually just pops right off. We'll see. :rolleyes:
