6.5x47 Lapua question

[want2learn]

I ordered a new barrel for my Sig .308 Winchester rifle in 6.5x47 Lapua. I gravitated to that caliber because it seemed to be an easy fit for my current rifle and the caliber is considered to be lighter recoiling, accurate and has readily available quality reloading components.

I was just reading the caliber choice thread....very interesting and informational.

On reviewing the aforementioned thread i noticed the following caution "Need to bush the firing pin". I'm not sure what that means? Will i need to modify or purchase a new type of firing pin?

I somewhat arbitrarily chose a 26 inch length barrel with the provision that if it proved a liability i could always have it shortened? Does the 26 inch length barrel seem appropriate? I understand that rifle balance is important but i have no way of determining this without barrel in hand.

I'm hoping to learn more about longer range shooting, 300 yards regularly with occasional sessions at 750-1000 yards. I won't be hunting or hiking with the rifle.

thank you

That extra length youre trying to cut will help you down range specially 1k yards...
X47 are known as medium fps SA every fps count.but again i was shooting 1k yards with 24" 130gr bullets with great results

26" will be good for it. Accurate and very easy to load for round. I had one and was shooting 140 hybrids at 2750 with great accuracy.

I run a 24" barrel and a suppressor on my x47. I have taken it out to 1000 meters with no issues.
When the time comes to rebarrel im not sure which way I will take, sometimes I lust for a bit more speed, sometimes I wish for a handier rifle. So I might go either way. A 26" barrel will do the job just fine.

I love my 6.5x47. Mine is 26" plus a brake. Before this all my rifles were 20". Now I really don't mind the extra length, before I always thought I wouldnt want it. I am running mine with 123 Scenar bullets and a little on the slow side at 2815 FPS. Still way better ballistics than my old .308 and a lot less recoil. I'm hoping to get decent barrel life out of it at this speed but we'll see.

If you start cratering primers and piercing them you may have to send the bolt off to be bushed. Long Rifles Inc. website explains it very well if you don't understand. You can try using primers with a harder cup like the Fed Gold Medal AR primers and it may help.

thank you all so very much. appreciate the information. can't wait to receive the barrel, hopefully in another month or two

Whether the rifle is going to need a FP hole bushed is dependent on:

• The FP hole diameter (use gauge pins to accurately determine the diameter)
• The Firing Pin fit to the FP hole (loose fit is going to get primer puckering)
• Primer cup hardness/thickness
• The pressure of your loads

If your FP hole is in above 0.070" you may experience pierced primers with book loads. Bushing usually reduces the FP hole to approximately 0.065". I wouldn't fix it until I know it needs fixing....

thank you...makes a lot of sense.

really looking forward to learning more
