Longrange shooter Report post Posted December 22, 2010 I have several long range rifles I have built two have a 334 neck in the barrel so I size my brass to 333 so I only have one thousands of space my new rifles are 336 and I use the same brass at 333 so now I have three thousands clearance does any one know if either one is better so far the tighter one with only one thousand clearance seems to shoot better groups. the shell is a 338 Lapua necked down to 30 caliber shooting a barns tripple shock 180 grain with 100 grains of powder vitavori 24n44 thanks Longrange shooter Share this post Link to post Share on other sites
jeffro Report post Posted December 22, 2010 Most tactical/hunting rifles run no-turn necks. This is do to the rifle being made for reliability and so it will function in all conditions. ie: dust dirt. On the other hand bench rest guns run turned necks. The tighter everything is the better I would think. What kind of groups are the guns shooting. Share this post Link to post Share on other sites

jeffro Report post Posted December 22, 2010 Sounds like a very nice rifle, with great componets. Are you shooting 2 shots per group. Share this post Link to post Share on other sites
Longrange shooter Report post Posted December 23, 2010 Yes I have been shooting two shot groups when the rain quits later this week I am going to the range to redial my right hand rifle then shoot it out to 700 or 800 yards to be ready to use on the first for coues deer.

jeffro Report post Posted December 23, 2010 Just my opinion, but I would shoot at least 3 shots per group if not 5 shots per group. This will give you a much better idea as to what is really going on with the load/rifle. On a barrel burner like this I would shoot 3 shot groups so the barrel doesnt get too hot, and you dont use up too much of a short barrel life. Share this post Link to post Share on other sites
Longrange shooter Report post Posted December 23, 2010 I will try that three shot groups later this week thanks Share this post Link to post Share on other sites
