Re: Long range barrel profile

Goodgrouper and UncleB, maybe you know something I don't know. What's the typical 20-shot group accuracy you think someone could attain at 800 yards with one of those whippy, 30-inch long Palma barrels that's only about .800-inch at the muzzle weighing about 5 pounds?

Benchrest competition rifles shoot aggregates of several 5- or 10-shot groups that average about 1/2 moa at 600 yards and about 7/10ths moa at 1000 yards with their stiff barrels. And yes, these rifles sometimes shoot a single group that's smaller. How do you think a whippy, less stiff Palma barrel would compare?

Re: Long range barrel profile

Thanks to everyone for the replies.

Guidance from those more experienced and more informed that than I am is always great.

Meantime I realised it was a dumb question (so my apologies) because the profiles don't differ that much that the variation in the barrel channel of the stock will be more than a couple of mm's - or say around a 10th of an inch - and that's a gap of half that either side.

#7 Lilja it is - and I do hope at some point to get a Lilja. I once e-mailed a question to Dan Lilja which didn't relate to one of his products and he was happy to answer my queries and share his experience. I decided to support him at the next chance I got.

Thanks again.

Wim

Re: Long range barrel profile

Dave,

If you don't mind me asking, why would you want to get rid of a 1 in 7 7mm?

Re: Long range barrel profile

Mag, i'm not good at explaining things but to sum it up in one word it would be "finickyoverboreness" i'm not going to try and explain it because i'm a 2 finger pecker and don't have time. if you give me a call, tonight would be good, i'll explain it in detail. 717-597-7027 EST.

Re: Long range barrel profile

Thanks for the offer, Dave.

You'll see that my question was based on next time I rebarrel. Currently the rifle is a .300 Win Mag, Shilen #5 and I wanted to order the stock based on an appropriate contour for next time around. currently the rifle doubles for some (heavy toting) bushveld hunting (lots of walking).

Thanks again and thank you all for the input.

Wim

Re: Long range barrel profile

One of the main reasons for the long barrels on TR (Palma) rifles is sight radius, also i presume it works the same way in the US, shots are called and pointed by the butt marker these are then recorded by the shooter he will then wait for a right condition to fire his next shot.
sometimes 2 shooters will engage the same target allowing even longer times between shots, so what i am saying is, barrels dont become hot enough to affect accuracy.

Ian.
