Hello all. Kentmax5 from southeast Texas. have been doing a lot of research online and talking to friends and fellow hunters and am just about ready to pull the trigger on a Long range hunting/target rifle. I have a local gunsmith here who is a legend in custom rifle building in my area. So am weighing the pros and cons and price tag of having him build me a custom gun or ordering one from one of the online sites I have found. including Hollandguns.com. I am torn between a 7mm mag or 338 for my custom rifle...and I now know that there are more than one type of 338.....I'd only heard of the lapua until recently.....any and all input is appreciated. I am looking at a 500-1000 yd. ethical effective range on medium to large game. Thanks.....Kentmax5
