Fireform?

[busse fan]

Do I want to fireform my cases prior to doing load development or can I use new brass and then reload it and expect the same accuracy?

the reason for asking is that I can get 300 rum managed recoil for almost the same price as new brass. Managed recoil is fireformed when I shoot it though.

Thoughts?

"Do I want to fireform my cases prior to doing load development or can I use new brass and then reload it and expect the same accuracy?"

Any such minor things MAY (or may not) affect accuracy but it won't be much if it does. Like "neck sizing", "fireforming" is a much over emphesized web topic.

Don't bother with somebody else's used brass for YOUR gun. It all has to be prepped your way, fireformed to your chamber, and reloaded with your tools, before there is any real use in load development. So might as well use new brass.
Everything changes from first use in your chamber, no matter what.

I concur.

Also, I'd want to control the brass prep right from the start and record the data so that I would know exactly what to expect with new brass in the future.

Besides, why waste barrel life and practice time with sub-standard ammo?

Alright, thanks. I'll buy a box of managed recoil to break in the barrel and set the scope up and also some new brass.

Wait a minute there seems to be alot of quick answers here to a question that was asked without providing many facts. What type of brass is the Managed recoil ammo loaded with?. Secondly what type of brass are you considering purchasing.

If you are going to use Remigton brass then this is a good way to get it.

When Breaking in a barrel that is what i recomend. If you look at the price of brass,bullets,
primers and powder it may exceed the cost of loaded ammo so then the price of the managed
recoil or the level 1 may be cheeper.

Fire forming in a standard chamber with standard ammo is not a must but it can help in
the case prep and sort because it matches your chamber dimensions (More uniform).

New brass has rounded corners on the shoulders and necks and after fire forming they are
crisp uniform for case prep.

I hunt with some new ammo and when I get enough (Minimum 100 rounds) I will set up and
reload for better accuracy.

This is what I do and seems to work well with the Lee Collet Dies since they require fired formed brass prior to resizing. I've used the 'Power level I' and 'managed recoil' factory loads from Remington when on sale. Like you mentioned, it's a cost effective way to get fire formed brass. I use the reduced recoil stuff to practice field shooting techniques (off hand, sitting, kneeling, etc.); some non-long range shooting competencies that are important.

I dont think this low pressure/low recoil ammo does much damage regarding barrel life either.

Yes the managed recoil is remingtom ammo. I was thinking buying remington new brass as the only other brass I can get locally is federal and from the searching I've done it doesn't seem like a good choice.

It depends on the level of accuracy you want. For shorter range plinking and hunting, probably not, but fire forming a is just one of the " little things" that seems to help, like neck sizing (worth trying), brass sorting, etc. the more prep work you do, the more consistent the load, noticeable at longer ranges.
