I am building a light weight, Remington 700. I plan to shoot 75 grain Gold Dots. I am considering a Pacnor 1 in 8 twist, 22 inch lightweight barrel, which number of grooves do you guys prefer and why? 3, 4, 5?

PM Renegade50. He shoots 75gr gold dots exclusively and has a few pac-nor barrels.

Probably a 3 groove. Less fouling too.


I’d ask Pacnor.

I'd do 3 groove 1:7" twist.

I'd do the 5 groove. Kirby Allen determined some years ago thatc3 Grove shoots out faster than more grooves



I got banned on another web site for a debate that happened on this site. That's a first

Up & running

They built me two new barrels this year...

20 Vartarg 10 twist/3 groove--Savage pre fit

20 Practical 10 twist 3 groove--Savage pre fit

Great products & very accurate barrels--L O N G lead time

Some bullets may have thinner jackets the 3 groove may affect

Remember having a 6XC---8 twist/3 groove...would spin the jackets off a 75 V max within 100 yds

Switched over to the 87 V max......problem solved....helluva LR p/dog rig

Pac Nor offers a Polygonal

Never built one but always had an interest

My H&K pistols have polygonal rifling

They are more accurate than me

I have a 3 groove 8 twist pacnor 223 ai. It shoots well but if given a choice I lean towards 5r. Some say 3 grooves hold up longer with less fire cracking etc but I've seen 3 grooves become hard on jackets pretty early. I think the wider lands get a little rough and start chewing up jackets. I've known some guys that used to run fast twist 3 groove Lilja's but found they were poofing thin skined bullets early on. I think you'd be fine either way with a 223.

Think lightweight and that pretty well rules those two out unless you want your gunsmith to turn to your preferred contour.

See above.

Rock Creek and Benchmark will make you a small contour stainless barrel that is cut rifled, though.

They did have a bad fire. But they are back up and running. I just got my 25/222 back from them. Been too dang cold to get to the range with it yet.

Left handed mini Mauser. I sent them two actions a couple years back. They had the 25/222 ready to ship and the 222 just a day or two from shipping. The fire happened the next day. They refunded my money plus the cost of the actions. They were super to deal with.

I sent this one to them and when I got it back it had been incorrectly chambered. The tech used a 223 head space gauge with the 25/222 reamer and ran the reamer in until it would close on the 223 go gauge. Of course my first shot the case came out not looking as it should. I sent it back. They turned it around in three weeks. Including cerakoting. Mistakes happen with any company. Their customer service is first rate. I have three of their barrels and will have more as funds permit.

They did my .338-06 AI prefit for the Savage. I have three other barrels by them, if I do another it will be them again.
