Article on how to sight in a scope. Needs review.

JimKirk, thanks for the comment. When I speak to people about these issues at the range, I can direct them through this process quite quickly. But I am not sure I could make it into a check list, because there are a lot of decision points. For example, is there space on the 25 yard range? Then take the first shots there. If not, then use a different strategy to get on paper at 100 yards.

So overall, I think that people really need to read the article to understand the whole process.

I understand the need ...

The last time I was at the range dialing in a new hunting round the guys next to me put 100 rounds through a .270 in about 45 minutes. I can guarantee you they damaged the throat on that rifle.

Arsenal's put 270 rounds of 30 caliber match ammo firing 3 to 4 shots a minute with precision match grade barrels. Each barrel is good for ten or more such tests before accuracy degrades any significant amount.

Last time I checked, Sierra Bullets test barrels in 270 Win used to get accuracy data on production runs on 270 bullets were fired 4 to 5 times a minute for 10-shot test groups. Once every 15 to 20 minutes during each run. Those barrels lasted 2000 rounds of accurate barrel life; about 1/2 MOA or better groups at 100 yards with best quality bullets.

I've seen some M1 and M14 front parts smoke after shooting an Infantry Trophy Match ("Rattle Battle;" a common name) shooting 24 shots in 50 seconds. When we watched them, all those who had visible smoke coming out at around their barrels, we said "Over lubed rifle on point X" as correctly lubed ones never smoked. There's been a few who didn't watch out and touched their neck to one of those hot barrels; instant second degree bur

When I was with the AMTU back in the dark ages we all had separate rifles for the rattle battle event. I've had mine so hot oil seeped out of the wood.

I think the Army and USMC teams both rattle battled their regular match rifles at the ends of their barrel life. Primarily because they had very good prone and sitting rapid fire zero's on them. Few, if any, USN team members did that.

It was often embarrassing to have ammo left to shoot rapid fire standing at 200 yards. One or two shots for two or three people didn't help scores very much. Especially if one round of the 384 issued to each 6-man team was left after 300 yards sitting; who gets to shoot that round all by himself?
