Home Forums Hunting & Shooting Express Rifles and Big Bores Only How much neck tension on 9.3x62?

I'm getting ready to send my new Redding FL sizing die to Redding to have them open up the neck a skootch. Normally for tactical shooting I like .001" to .002" neck tension.

This rifle is going to Alaska for Grizzly. The action will be a Pre 64 M70 with the focus on 250 gr Accubonds, first.

How much neck tension would you suggest in a rifle like this? Something which will give me long case life but not let the bullet seat deeper upon recoil.

Thanks,

Alan

I just sent a die in to get honed out for a 22 cal cat, and I went for .004" under loaded round. The reamer is a .250" neck, loaded round average is .247", and I specified a .243" neck on the die.

A skootch is a little vague. You need some hard numbers, and plan on the smallest loaded round diameter, unless you're turning necks.

I'd leave it alone, and anneal every time for consistant tension, long case life, and all the tension I could get on a bear gun.

I'd have to go out and measure but I use plain ol' RCBS dies on my 9.3's loading the 250 gr Barnes X and have never had a problem. Great accuracy and zero bullet movement. This is in FN Mauser's.

My wife hates it when I use "skootch" in my language. I usually use it as a term of endearment as I did here. I have hard numbers and am planning on using them when I send the die off to Redding.

Thanks,

I needed to crimp for the 289 and 320gr bullets, but not for the 250 A-Frames I shot in the 9,3X62.

I sure would not open them up a skootch.

Keep in mind your 9.3x62 will be a "hunting rifle", not a varmint or target rifle so neck tension is not particularly important within reason..I like about .003 to .004 in a large bore hunting rifle, that will hold a bullet and crimping isn't really necessary as neck tension alone holds the bullets very well in the 9.3x62 combined with a full case of powder, also keep in mind that the 320 gr. bullets (Woodleighs I assume) have not crimping groove..If a crimp is needed in a 9.3x62 chamber then it should be a very light crimp at best, and that depends on the chamber specs of your particular rifle..I sure don't want a bench rest chamber in a hunting rifle..
