If You were going to build a Hotrod, What Caliber would it be

[Plumsask]

That'd be me, built two of them, 108 ELD-M's at 3425 in a 24" barrel, with outstanding accuracy....

How many rounds down it now?

Coyote rig is a 6 SAUM for me shoots great - 108 eldm going 3490 (fairly light load but plenty fast)
Buddy is also shooting a 6 PRC sending Seirra 90's at 3800

25 years ago I had the same itch. I built a 6-06 on a 700 long action. 28 inch 12twist barrel. 70 grain Sierra bullets would easily exceed 4000fps. Accuracy node at 3950 with no pressure signs printed 1 1/4 inch at 300 yards consistently.
barrels lasted 600-1000 rounds if not abused. Later switched to 6-284 with very similar results. Took me until last year to get over it and sell all that stuff. Now I show off in the prairie dog towns with a 20-250. Have fun!

What is the twist rate of your barrel?

 

[Bill Norris]

For the most part, I'd say you pretty much already have most everything covered. I think anything you built, that you currently don't have, would just kind of be splitting hairs.

You could do a 22 Creedmoor but you already have a 22-250AI and 220Swift so I don't see much point. Another would be a 22-243 or 22-243AI but, again, you have the 22-6mmAI as well as the others that would be nearly the same so I don't really see any gain.

The only place you aren't already pretty well covered would be something in 6mm but you already have a Rem 6mm AI so the gains wouldn't be all that significant.

I guess if you just had to build something I'd probably go with a 6-284 or maybe even a 6-6.5PRC but you said you want to shoot lighter bullets and since you'll be using a LA Rem 700 neither requires a LA and I'd hate to waste a LA when you don't need to. One of, if not, favorite builds is my 6-284 and mine wears a 26in 12tw Lilja barrel. I shoot the 75gr Vmax and it's built on a SA Rem 700.

Shooting light bullets in things that are very overbore doesn't seem to always produce the kinds of gains one would expect. You could build a 22-284, that's a pretty significant hot rod but shooting light bullets it may not impress you, compared to say your 22-6mmAI, as it would if you shoot the 75gr and up bullets but a 22-284 could be something to consider.

I would not under-estimate the 220 Swift or 22-250 when it comes to speed. Back in the day (years ago) when Berger made the 35 gr. MEF coated bullet me and a friend were getting over 5000 fps with both rifles without pressure signs from either.

How many rounds down it now?

The first one I built was more of a LR plinker. I sold it and built this one as a lighter hunting gun. Since I had learned so much on the first one, load work was minimal on the 2nd.

I sold this one a month or so back with 167 rounds down the bore.

First one was a 7.5", this one was an 8".

Them 35 gr in my 22-6MM AI would really scream. I shoot Sierra 50 gr Blitzkings and get over 4300 fps.

Thanks, you made my barrel searches easier.

How did they handle the wind?

I ask because my 223, 1 in 12 just was awful at 300 + yards with 55's, I just couldn't reduce the time of flight enough. I dropped to 40's and the 300 yard groups and drop got allot better and the velocity went way up.

I did similar with my 6MM Remington, this was before the ELD designs were out. I dropped to 75 grain and the velocity went way up and 500 yard performance became feasible.

Best I remember we were shooting some 16 once drink bottles filled with water @ 200 and 300 yds. and was consistently making hits. With calm winds we were able to hit the caps fairly consistent too. The down side to those speeds of course was barrel life soon went away even with moly coated mef bullets.

I have a Remington 700 long action. And looking to build a speed demon. What would you build?

I like shooting light bullets so will not go with a fast twist barrel.

I strongly recommend you read the series of posts made by Fredo , and titled....
Gentlemen, I present... the ".220 Redline ".

This series by Fredo and his buddy Snert constitute ( what is, IMHO ) THE best series of posts ( or even magazine articles ) I have ever read; about varminting and wildcats.

Fredo lays it all out for you, going into great detail on wildcat design, case forming, re-loading, chrono data; and in the field results on groundhog, coyote; and later... deer.

Fredo is also looking into doing a new hyper-velocity 6mm.

I input a number of responses to Fredo's post. The Apr 09 2021 pg 22 input included quotes from renowned ballistician Homer Powley.

Powley's " Expansion Ratio " chart ( Guns and & Ammo 1974 Annual ) listed a value of 4,
as the lowest Expansion Ratio value Powley wanted to provide data on. The lower the
ER number,,,, the less " efficient " the cartridge is at turning powder combustion gases into useable velocity.

Fredo's .220 Redline as he configured his rifle, has an expansion ratio of 4.5; as I recall.
That is hangin' it out there in the corner of the .224" cal performance envelope !

Everybody's got decide for themself, how badly they want hyper velocity; and their willingness to perhaps accept things like elevated chamber pressures... and possible
lowered barrel life.


With regards,

Barrel life will suffer from the hyper-speeds and quickly as well.

I like wildcats. And being an avid predator hunter, I've gravitated toward 'hotrod' type cartridges...fast & flat is where it's at!!! Maximum point blank range and terminal performance on critters are key elements for a 'hotrod' to improve upon, over factory available cartridges. Ideally...

If someone truly wants a hot rod cartridge, I don’t think barrel life is a major consideration. A man definitely wouldn’t want to waste it shooting paper once load work up is done.

Yep, high pressure and speed is great for chuckers, the barrels last several years, bad for doggers they run them dry quickly. I'd have to do some hard thinking if I did the dog towns.

 

[IMMORTAL]

Build yourself a 300WSM with a 15 twist barrel. Shoot the 125gr. almost 4000 fps.

Just google Richard Franklin varminter.
