Help The Guy with the Broken QuickLoad :(

[Brian Pfleuger]

Loading 270WSM

Case length 2.100, capacity 81.0gr

Bullet 90gr Sierra, length .843

OAL 2.677

Barrel 24"

Looking for loads for IMR3031, Win748, H380 or whatever works best if those 3 aren't good.

TIA

A couple that looked promising. The three powders you listed are way to fast for this application.

 

[Wyoredman]

Try the Rl-22.
Please

 

[Brian Pfleuger]

Thanks!

If anyone feels like it, which powder gives best velocity with a 58k psi limit?

[Brian Pfleuger]

Try the Rl-22.
Please

Why?



Thanks guys. It's looking like IMR4350 is a good place to start. Lyma shows it as their accuracy load for the 90gr too.

Looks like their max load of 70.0 might be right near 58k too.

All the "4350"s look OK actually.

 

[Jimro]

Peet, can I ask why you are looking at such a light bullet in such a big case?

Jimro

 

[Brian Pfleuger]

Cuz there are woodchucks and coyotes that need to be turned inside out.

I'm a fan of light and fast. Gonna use 85gr TTSX on deer too.

I have the WSM because it was what a guy wanted to trade for my shotgun. Wouldn't be my first choice but it'll be fun until I get something else.

 

[Jimro]

Heh, I figured it was either you had a lot of bullets left over from a 6.8 SPC or you were going to go "double duty" on a deer rifle for varmints.

Ever consider loading up some 135 SMK's and seeing how long a shot you can take on those 'chucks and 'yotes?

Jimro

 

[Brian Pfleuger]

I'm a little concerned about ricochets on the woodchucks. Can't shoot the yotes from that far away. About 250 is max. Could get 550-600 on chucks.

I'm pondering differences in bullet construction and load data again. It seems odd to me that I can (according to Barnes) push an 85gr TTSX at 3950 but I can only get a 90gr conventional bullet to 3700. I would expect the opposite.

 

[Jimro]

Comes down to bullet resistance in the bore, lead sheathed in gilding metal deforms more easily than solid copper (or more precisely, low zinc content brass).

As far as ricochets go, I wouldn't worry about that with any lead cored bullet at the velocities you are talking about, the impact with the chucks will likely cause the "grenade effect" on any chuck you hit.

Light for caliber bullets at high velocity disrupt much more quickly than heavy for caliber bullets at regular velocity, it has to do with the lower sectional density allowing the soft tissue to disrupt bullet stability more quickly. Same reason why M193 is a better choice for lethality over M855 at ranges under 75 meters.

Jimro

 

[Brian Pfleuger]

Yeah, I'm not worried about ricochets with the 90s, I was meaning in reference to your question about the SMKs.

 

[mrawesome22]

Match bullets have very thin jackets much like a varmint bullet.

 

[Jimro]

I wouldn't worry about SMK's ricocheting at ranges over 100 meters, in my experience they disrupt and deform very quickly on impact. If you have access to a lath you can open up the open tip a couple of thousandths and watch them open up even faster. An operational sniper I knew working with a police SWAT department chucked his issue ammo in a lathe and uniformed the tip that way to ensure clean terminal ballistics without affecting trajectory.

Jimro

 

[FrankenMauser]

The Speer 100 gr "Bucket Mouth" HP has shown to be more accurate and more destructive in every .270 in my family, when compared to any other 90-110 gr bullet on the market (with the exception of the 110 gr V-Max).

I don't like the 90s.

 

[Brian Pfleuger]

Well, I've got 100 Sierras to burn through now.

I'm just toying around with it. There won't be many times I reach for a 270WSM woodchuck gun when there's a 1/2 MOA 204 Ruger right next to it.

 

[huntinaz]

Cuz there are woodchucks and coyotes that need to be turned inside out.

Post a pic of a dog when you get one, eh?

I'm itching to smoke a dog with a 140gr Accubond inside 100 yards with mine.

I'm just toying around with it. There won't be many times I reach for a 270WSM woodchuck gun when there's a 1/2 MOA 204 Ruger right next to it.

You'll keep thinking that, right up until you see what a 3,600+ fps 90 or 100 grain HP does to the same animal. It's a beautiful thing.
Even with varmint cartridges available to me... I always have, and always will keep some Speer 100 gr HPs loaded for the .270. Having twice the bullet explode in the animal really does make a difference.

 

[mrawesome22]

I save the pelts on nice coyotes and a 110 vmax out of my 30-06 was incompatible for that purpose lol.

Shot a ground hog near a fence line and there was strings of fur and guts and meat hanging all over the barb wire.

Grusome for sure.

But, why when the Varminter is there and shoots like a lazer beam.
