.243 Win 110 SMK load data

[Deleted member 10043]

Has anybody kept records or currently shooting this combination of 110 SMK with .243 Win. I can't figure out why Sierra only has load data for 6mm Creedmoor for the 110 SMK. I found a bunch of these bullets in storage I forgot I had.

It is due to barrel twist rates. most 243 rifles are 1:9-1:10 twist, which will not stabilize anything over 100 grains reliably. Hodgdon and Hornady have data for heavier bullets.

I got some old old reloading books I can check if you would like.

Sierra's app has data for that combo. What powder are you looking at?
It is not a traditional chart, but has a slider at the bottom so it is hard to post min and max without knowing what to focus on.

This question is obviously for people shooting it with a 7 twist barrel as recommended by Sierra.

What app?

 

[Deleted member 10043]

Anyway, lets say H4350

What app?

The Sierra Bullets reloading Manual App. Basically mobile 6th edition of their manual. Not free

You can see how the app is a little weird to deal with, but here is min and max with H4350.

I get that, but that is the reason for less data available for this combo vs 6mm Creedmoor.

The app is cool. What does the double red asterisks mean.

I use 107 smk’s in my 243. 1:7 barrel. It shoots the 107s and 95s lights out. The problem with the 110s in the 243 is that you have to seat them so far back unless you have a custom chamber.

Try the 107 243 from Spark Munitions and see how it shoots out of your rifle. I think you’ll love them. That’s what I run.

Close to or max load

I shoot 107 smk's with WAY over book loads of H4350 in my 8 twist shillen.

I'm going to try them in a LA .244 Remington barrel, lol. Fuck the 6mm Creedmoor

 

[Deleted member 10043]

Yep, .244 Remington with 4350 is the shit with 1:7 28" . Basically, the same load and jump I use for the 107 SMK.

I downloaded the app the other day and it was free?

Reload data requires a paid subscription.

I just opened it up to check and can view reloading data.

Maybe I need to get screenshots of what I want before Sierra realizes it's listed on their free app.

 

[Deleted member 10043]

There is a free trial period than about $5 per year

Ah. Makes sense. I only have one load to develop with the sierra's. The books are much easier than their app but $5 isn't bad if I ever want to play with the load in the future.

The Sierra app has it, what powders are you looking for data?

Thanks. Look above. I figured out how I want to throw them.
