Chronograph SD questions

I am still somewhat new to long range but expanding my knowledge and experience as much as I can. I just picked up a Garmin Xero chronograph with the intention of getting into reloading relatively soon. It’s an amazing unit and super easy to use, but I have a couple questions. What is the appropriate number of shots to measure for an average? What are considered good or bad SD and spread numbers?

I have measured a lot of groups across multiple rifles. Most of the Hornady and Norma factory ammo has come in with SD’s from 13-20. I recently measured 12 shots of 7PRC ammo from Choice Ammunition(Berger 168 VLDH). I was surprised to see SD at 45 with spread of 81. I then measured Hornady 175 ELDX Precision Hunter for 7 shots and got a 13.4 SD with 45 spread. The Choice groups well at 100 yards but I haven’t taken it past 400 yards yet.

What should I typically look for and consider good for factory ammo?

What is the right number of shots to base my averages off?

I appreciate any wisdom, best practices or advice that you can share. Thank you.

Inherited a Rem 700 5R Milspec

A prolific firearms collector(1000s of guns.) Of all types recently passed and I was given a chance to pick 2 firearms. Picked a Sig 716 patrol and the Rem 700 5R. I have shot it a little with a cheaper scope. Deciding on a better than good optics for it. I cleaned it down to metal since it had been shot. It is a precise rifle haveing squeezed one or two 1/2min 5shot groups out of it with hornedy 168gr match. But it's not the most consistant.
My question is how close to a legit M40(exact model?) is it? I don't think it's a world class barrel or anything haha.

Another attack directed at the capital of Americana and the shooting sports culture.

The Tennessee legislative session starts next Tuesday on 01/14/2025 and several non-profit orgs, including the antigun group "Voices for a Safer Tennessee" are hoping to push their "concerns" to legislators to pass new antigun bills.

I have absolutely no, ZERO interest in reaching any "common ground" with leftists and their invasive pest ideology, nor even spending any effort to listen to what they have to squawk out of their yappers. Leftist policies have done nothing but render populations of hardworking people disarmed in their jurisdictions, livelihoods and businesses ruined, homes and businesses burned, and economies circling the drain. There is only ONE message that needs to be sent to those who want to further desecrate home and hearth. And that is:

OHIO: GOV. DEWINE SIGNS PRO-GUN LAWS INTO EFFECT. Updates on Post no. 8.

A 3rd world nation for certain now


Most populous state and worlds 5th largest economy and they need Mexican firefighters to put out fires - how they are going to do it without water I have no idea but obviously NO ONE in CA has any fucking idea how to do it .

MDT Bipod - NRL22, is juice worth squeeze?

I finally bit the bullet for the MDT double pull, I've been using it for about a week through a few different rifles.

For NRL 22 specifically, I don't see any reason to drop the coin on this thing. PRS, NRL hunter, field shooting whatever I get it. Does anyone who shoots NRL22 really prefer this over an atlas?

The versatility of it is great. But it's not $400 great and I've yet to see an NRL stage, or PRS for that matter that calls for it.

Is 2025 Year of the MPVO? Two New 2-12s!

Barely two weeks into the year we already have to new MPVOs:
-Primary Arms SLX 2-12x40
-Element Helix Compact 2-12x42: https://element-optics.com/product/helix-hd-compact-2-12x42/

Just a shame both are SFP with capped turrets, the Element even being MOA only....
Maybe 2026 will be the year MPVOs return to glory.

My gas well keeps freezing

My gas well is about 500yds from the house, and there’s no electrical over there. The pipe/valve keeps freezing up when the temps drop into the low 20s and we when we get snow.

We’ve tried building wind breaks around the pipe, wrapping the pipe in foam insulation, etc. but it keeps freezing.

The well workers installed an alcohol drip tank and valve for us. It does work to thaw the valve out and get gas flowing again. But walking from the house at 3am in a blizzard to do it is a headache.

Anybody know of some type of solar / battery system that could power some heat tape we could wrap around the pipe?
