Comp. build Question.

[LOBO151]

I'm wanting to build a bolt gun for Tactical matches.
I'm thinking.... somthing lite, short, and flat shooting.

So, I fig. a rem. 700 XM3(clone) in 6.5 X 47L. W/ 18.5" fluted Bbl.

What do you comp. guys think?

...Should I go longer, than 18.5" on the Bbl.?

...Diffrent stock, or cal.?

Please, any info will help.
I would like to get this build rolling!

Re: Comp. build Question.

lite and comp gun don't belong in the same sentence....

most tactical matches are won 300yd. and in

the 6.5 is a great choice

Re: Comp. build Question.

I keep saying it based on another users experience but I would op to have the barrel melonited to gain velocity lost from cutting the barrel down.

Many have gained anywhere from 25-75 fps using this process.

I say a Manners Mcs T3 or T2 (non adjustable) stock with 90% carbon fill, M5 bottom metal since it's a good bit lighter then the Surgeon, and a GA Precision Gladius Contour barrel. From what I have heard you will save more weight with a better contour then fluting a short barrel.

Something else to consider. The 6.5x47L uses higher pressure to achieve similar performance to the other 6.5's because it has less case capacity. Chopping that short is really going to cut the legs off the round because you'll have to download it to reduce pressure.

I'd run at least a 20" if not a 22" barrel. The velocity gains will out weight any benifit of having that short of barrel. Minimal weight difference if you calculate it. I think RL17 will be your best friend with a shorty pie rifle.

Re: Comp. build Question.

Basically depends on what sort of comps you're talking about. Do you want to enter long range benchrest type comps or are you looking at tactical comps where you'll be shooting at an assortment of ranges and at different positions?

The reduced bbl length would obviously be a factor in mv. I don't follow how this would also increase load/pressure per same chamber.

Sorry,
I'm wanting to compete in the Tactical comps, where I run/ walk and shoot
at diffrent stations. Thats why I fig. short and lite.

Im not the biggest guy...So, I don't want a "boat anchor".

I have a 700rem. 308cal. with a 22" 5-R M24 contour (Rock) in a AICS. It was built by Predator Arms....But, it's a ton. of gun! I don't see me "running and gunning" with it!

I also have a FN A3G action in a McM A-5. That I had RE-Bbl.(Predator) to .260cal. W/ 28" fluted
AMU contour. It has a Badger M-5 lower....But, I think it may B to long.

Last, I have a TRG-42 300WM. W/ a TRG brake. It not bad to lug around. But, it's long and may B over kill W/ the 300WM!

I was trying to find a "happy medium". But, I have never competed in a full-on
event.
Thats why, I posted here for help!

Re: Comp. build Question.

.260 or .243 with a medium or heavy palma finished at 22-24". I went with a .243, heavy palma, 26" and it hangs to heavy out front, great for prone, not so hot for awkward positions. If I had to do it again I would go .260, 22" heavy palma fluted. I dont think the .260 looses near as much in a shorter barrel as the 6.5x47 or a .243.

That med. palma, was what I was looking at doing.
why would you go heavy/fluted?...So,it Don't heat up as fast?

Re: Comp. build Question.

The barrel profile has a ton of influence on the weight. A longer barrel is going to give you more performance and if you are competing you want performance right? So, I'd go with a 24"-26" barrel in a Light Palma contour. This contour is heavy enough to stay tight over 20-30 shot strings, but plenty light enough to keep your rifle handy. A lot of XTC rifles are in the 13lb range and that might be a good target weight for you to consider: 12-14 lbs including scope & sling. You don't want the rifle too light because the recoil will start impacting accuracy, especially over extended strings.

Longer barrel does not equal better/more performance. That depends again on what he's doing. He stated he is going to be cimpeding in tactical comps. A 20" or 18" barrel will do everything a 26" barrel will do 600 yards and in.

In a tactical competition a short barrel is your friend

Re: Comp. build Question.

Consistency trumps speed... knowing your dope is all that is important. Doesn't matter if the extra speed shaves .3 mils off the call, if you understand your rifle and dope everything else falls into place. You'll beat the ballistically better performer with a less educated shooter.

The winners know their system better than anyone else, they are not out beating them with speed but beating them by out doping them. The rifle's dope <span style="font-weight: bold"> "is" </span> -- knowing that will reduce all challenges to the simplest solution possible. Thinking you can beat an unknown with extra speed rarely works out and is certainly not consistent. That only works when <span style="font-style: italic"> "all things being equal" </span> is mentioned and in competition all things are never equal.

You want a balance, handling and consistency. I would rather have a little slower rifle that I can maneuver with, than one that only gives me an advantage at 1000 yards, because as Boiko said, most tactical competitions are won inside 500 yards. I need to be able to shoot positional, supported, during extended movements, fast, slow, under a variety of weather conditions. Building a stick to win from the car to the line is not gonna cut it. One rifle has to do it all, maybe required to work wet, cold, dirty, dry, when you are personally being pushed to the limit. Speed is not the end all in this game.
