Cast Bullets in a Contender Barrel w/ Muzzle Tammer
« on: February 15, 2004, 07:06:53 AM »
Hi,

I'm new here, just happened onto the site while doing a search for 'LBT'.  Great site, wish I would have found it a long time ago.

My question is this:  Can I expect reasonably good results from my 14" 7-30 Waters barrel with muzzle tammer using cast bullets?  

This barrel is a tack driver with several different jacketed bullets but so far my attempts with cast bullets have not been very good.  I am using a LBT 145 grain LFN bullet.   I really haven't put a whole lot of effort into tweaking my loads for this bullet  and before I do I wanted to ask you guys if any of you had had good luck using cast bullets out of  barrel with a muzzle tammer attached.  Going through so of the old posts I read something about problems trying to do this.

Hey, thanks alot for your help!

Ken,
The brake is usually far enough away from the muzzle crown that when the gas finally exits, the bullet is on it's path. The ports in the brake that the gas exits by are in my opinion, large enough that the bullet isn't canted one way or another from the force. My best guess on your accuracy issue with cast loads is the copper fouling. Bores have to be either scrubbed clean of copper/guilding metal fouling or be dedicated to cast loads. I had a 12" Hunter in 30-30 and got it due to the thing not shooting cast loads properly. I scrubbed it with Shooters Choice until the patches weren't green any longer and the barrel was a one holer. The brake will have the same effect on jacketed as it does on cast so regarding it's effect on accuracy, it is like an old wifes tale.

Go for it, other than a little junk on the muzzle break is your only issue, I do all the time...my old 14 inch hunter in 44 mag probably had 9-10,000 rounds of lead heads through it before it became a 444 and now has many more.

  Shoot and have fun.

I have put several hundred lead rounds down my 375 jdj with no troubles. I have seen some lead and lube build up around the break but with normal cleaning it comes right off. the 375 jdj shoots to about the same point with cast as it does with jacketed
