IMR 4350, what primer to use?
- Thread starter chemo
- Start date
4350 in a M14.
Dont Do it
Go buy a reloading manual, one that has specific data for M14's.
Hornady has it's own data for the M14.
And quite getting data from sources not proven to be reliable. Like the internet, and so called experts.

X2. I'm a fan of IMR 4350 but I don't think it's the powder you want. And from the Hornady manual for a service rifle, and on powder for it, Hornady says " We achieved outstanding test performance with VIHT N-135, VIHT N-140, and VIHT N-150. Good results were also obtained with RL-15 and Varget".
All of that said 4350 works well in all my M 14 shooting cast bullets. There are a few truisms above that aren't so true when you move to shooting cast bullets.

Curiosity got the best of me as IMR 4350 seems to be a very slow burning powder to use in a 308, even using jacketed bullets. So I checked an old and new edition of Lymans Book of Cast bullets, the RCBS Cast Bullet book and Pet Loads by Ken Waters and I don't see loads with cast using IMR 4350. Actually, very few even with jacketed bullets. Just wondering Bob, what bullet and weight are you using as well as what charge of IMR 4350?
I have tried loads from 30 gr to 40 gr of 4350 with mixed results under Lyman's 311291 bullet. Below 32 gr. the acton would not cycle but accuracy was ok but not spectacular. 37 gr had vel running 1850 fps with resonable accuracy. I have since switched out my rear sight to a GI sight and when time permits see where the load takes me. Right now I am using 4227 under the same bullet with much better results. Reloader 15 has also worked well. I don't play with the old style jacketed bullets....real men shoot lead!

Thanks
. I have a buddy I worked with when I was on the tools that has an M 14 and thought I'd ask as I have access to a good local supplier of cast bullets. I basically use cast in all my handguns and for the following rifles; 303 Br, 348 WCF, 44-40, 444 and 45-70. Thanks again.Thanks
John if you go to the Cast Bullet Forum there is a long thread in the Military Rifle section started by Bruce B on cast loads for the M 14. I don't think 4350 is the best load for cast bullets in the M 14 but it does work, contrary to some of the above posts. You might want to take a look at all the work Bruce has done working up loads for his M 14. Very interesting.

Well do and I'll take a look at the Beartooth Bullet site also. I've obtained some good info there in the past.
Thanks again

oh you guys, so many replies and only 2 people could answer the question
I'll use it either way, if not in the m14 it'll be in something else, and I still needed to know what primer to use...
thanks
I didn't call anyone an expert, are you an expert? IIRC (actually I DO remember correctly, I can go back and read it) it was a suggestion, no one forced me to do anything.

Good advice, I've personally gained a lot of useful info when I have gone out and bought the specific manufacturers manual for the bullets I'm loading.
My different manuals can be at odds for different start, max and accuracy loads. IMHO CGN is a reliable source of load information. You registered in 2004, I would readily take your oppinnion on a load after checking it in my manual for safety.
Charles,
Oh and I use regular primers in my 243 pump with h4350. Not that that helps you.
"...is a short magnum powder..." Used in WSMs and regular Magnums, but it's not specifically made for 'em. Doesn't need magnum primers. A regular primer will do nicely. IMR4350 works extremely well in the .243.
"...4064, preferably 4895..." IMR4064 gives more consistent accuracy than IMR4895.

You're right, sorry about that
. For the most part I use CCI primers and in the Speer manual that's the primers they list in their loads. In loads for the 308 Winchester it appears they use a standard CCI 200. The same seems true for the 30-06 and that's what I use in mine. I also use IMR 4350 in my 308 Norma Magnum and 300 WM where I use the CCI 250. At a quick look, it 'seems' that they don't go to their CCI 250 Magnum primer until the IMR 4350 charge size goes over about 62grs. So, I would say you won't need a magnum primer.

I've recently tried IMR 4350 in my 348 WCF with Hornady 200gr FP with good results. I've just obtained some 220gr & 250gr Barnes originals and plan to try IMR 4350 and IMR 4064, the primers, CCI 200's.

Thats true, between hogdgon's data and sierra data theres a huge margin for alot powders and bullet combos, check it out (308win at least), both are available online if you dont have the manuals
Use amagnum primer in "magnum" sized cases. So if it's bigger than a 30-06 case, a magnum primer may be appropriate. There are lots of theories, but I keep it simple and stick with that.
.308- Standard rifle
.300WM- Magnum rifle
.223 -Small rifle primer

Simple answer : standard CCI 200's.
Good reading about loading for service model gas guns in the Sierra Manual. Sierra also recommends no powder slower than IMR 4320 on the burn chart for service rifle loads.
Gatehouse's "KISS" principle is sage advice.
One exception: many prefer the appropriate sized magnum primer for ball powders, especially when used in cold weather. Several (but not all) manuals recommend such.
