TAC ? What is it ?

 

[DrMike]

TAC is a powder marketed by Ramshot.

http://www.ramshot.com/products/rifle/?view=4&product=TAC

 

[Laker_Taker]

I went to TAC last year and 40 grain bullets in my 222. my 12 year old started shooting left handed after being taught to shoot right hand for 2 years. (right handed left eye dominate). his first 3 shots left handed you could cover with a dime. so I hung a dime and now it worth 9 cents.

That is an encouraging group. I'd say your rifle is responding well to that load.

 

[FOTIS]

Tac is wonderful powder as is 4198 for the triple deuce.

 

[SJB358]

Nice shooting!

I will have a 222 one of these days. It is my favorite 22 caliber centerfire.
