NRL build - barrel and scope questions

[codym]

Any idea what the barrel weight came out to?

No I weighed it but didn’t right it down. That setup as pictured with a modded triple pull was 12 pounds on the button.

The chassis and barrel profile are easy ways to cut weight. Light weight suppressor will help too. my guess is that you could probably get away with a #5, #6 hunter profile or light palma without worry about your barrel walking . You could potentially get away with a #4 but that would be cutting it close

I'm not winning any matches, and I shoot matches with a .30-06, granted, but I've never gone above 10x in an NRL match. I cannot imagine any scenario where I would even think about going to 30x+.

Even if I were shooting a lady gun in 6.5 I'd never want to go past 15x

The recoil on that big super manly WW1 30 cal probably dictates how much zoom a guy can get away with without losing sight picture. I think for most lady shooters like myself, 14-18X zoom is the sweet spot.

What's not feasible? If a carbon barrel and a steel barrel weigh the same, why is the balance any different other than the obvious possible differences on how that weight is carried across the length of the barrel?

As I mentioned, you have to go way down in contour with a steel barrel, which affects heat dissipation.

Weight distribution is a thing, too, as you said, but it's likely pretty minor.

I'm also specifically speaking about using an ACC for NRL-Hunter. My partner in shooting the Teams division used an ACC with Stiller action, #3 Benchmark, and LRHS 3-12x scope, and balance was certainly sub-optimal. He was a few ounces under 16 lbs. I wanted to use a 26" M24 steel barrel on my setup, but it wasn't even close to making weight.

Well its not like a carbon of similar weight is going to be any better at dissipating heat.

How did it get so heavy, Triple pull? The g2 ass end could get some weight out of there. There's a 12# rifle in this thread with triple pull, ZCo, and fluted rem varmint tube. Surely the XLR element isn't 4# lighter than an ACC.

Also, not sure if you've already got the chassis but gen 1 base was a fair bit lighter than gen 2 but gen 2 ass end is notably lighter. So if weight is critical, gen 1 base, gen 2 stock seems to be the way.

Yeah that's exactly what I said. 10x for what I shoot, 15x for 6.5

It's got a much larger surface area, so I'd bet that it is. A CF barrel of similar contour would be much worse, for sure.

Sorry, I misremembered. I also had almost a pound of internal weights in the ACC to help with balance, since I had the weight budget. Yes, if I took out those weights I could get away with another pound in barrel weight, bumping the barrel weight budget to about 5 lbs.

Tenacity with rail and pins: 31.875 oz
ACC Gen 1 w/o weights or attachments: 84.75 oz
2 internal ACC weights: 15.25 oz
TT Special: 1.75 oz
IBI CF Hunter 22" in 6.5 CM: 46 oz
Maven RS1.2 with AAD caps and Burris XTR Sig rings: 34.5 oz
Heathen G2 4-port and tuner: 7.25 oz
Ckye pod single pull: 21.75 oz
Burris scope level: 1.375 oz

Total: 15 lbs 3 oz
