Greetings,
Newbie here...........thinking of getting an 03A3 to shoot at local match.
Lots of info here for me to digest. I will mostly be shooting cast, so thats where I am trying seek info.
Question: 2 groove/4 groove ??? I am completely ignorant about this any input, or direct me to old posts on this is appreciated.
Thanks for any help,
Jon
Generally, the Army seemed to notice little, if any, difference. Most shooters who report range performance, seem to back this up.
About 20 yrs ago I rebarreled 3 rifles with surplus, new 2 groove barrels. A M1917, a Remington M1903, and a Smith Corona M1903A3. All 3 are fine shooters. The Remington is now my Elk rifle.
The 2 groove handles cast bullets very well. 600 plus yards and the 4 groove is best. Otherwise they are nearly equal.
If you decide to go with 4 groove, make sure you ask the proper questions before buying. One dealer is commercially cutting two extra grooves in a two groove barrel; the added grooves are the wrong size.
iv heard a lot of great things about 2 groove and the cast bullets.
I've heard that 2 groove barrels heat up quicker, especially during competition. Anyone experience this?
