Primers???? Ran out

Hey lads/ladettes,

I have a question regarding primers.

I had been using Federal large magnum primers but can't get any at the local here.

I have a good number of Cci large rifle no.200 primers.

I found using 70.5gr of ar2217 was my most accurate with my load with the large magnum primers. And was just about to go down the road of changing depths. But alas. No large magnum primers left.


What should I expect with the same amount of powder with the change of primers? Any changes and recommendations would be appreciated. Do i need to start over. I'm also at home for the week with the flu so would like to go ahead asap
TIA

Possibly a little less velocity with slightly lower pressure. Standard primers supposedly ignite at slightly lower temps that magnum primers. May or may nor change POI. You will need to shoot some to see. Usually changing one primer for the other doesn't affect accuracy much if you have good accuracy to start with but best way to check, of course, is to shoot a few and see.

You might find your velocity drops a bit by going from an LRM to a LR, with such a large amount of slow powder.

One way to find out. Test it. Then you can adjust accordingly.

Best to load up 3 to 5 and go to the range for a lookie.....

I will be doing the same once I get through my 1500

And also another question about seating depth. If I run my ammo to fit in the mag it is massively off the Lanz. .14"

I did the forced fit method and it measured 3.496"
Mag is 3.356"

Would be nice if it was accurate mag lenght. Thoughts??

Id start fresh with the brand change in primer . Your unlikly to run into pressure dropping but your results will likly vary meaning everything until now likly means nothing how many 215s do you need to keep going on the right track?

But then some goon would load a round nose to 3.496" without measuring the lands, jam it hard into the rifling, and blame everyone but themselves when they blew it up.

Sometimes affects accuracy of a load, sometimes not so much. Depends on the bullet, how well the throat of your barrel is cut, how straight your handloads are. You have several things to try to figure out if it matters or not. But generally I think most guys prefer bullets a little closer to the lands than your rifle allows. Somewhere from only just touching to maybe just over 1 mm away. Monometel bullets generally give best accuracy with more jump, around 1 to 2 mm. I would suggest you load yours as long as the magazine allows while still reliably feeding the action and see how you go. If you end up needing to change your bullet a more rounded nose projectile ( still spitzer shape but not as skinny in the nose as the very low drag bullets ) will get bullets closer to the lands without changing the COAL and still fit the magazine.

Iv got about 150 of these other primers so would like to use them up if they will work
I also am using 162gr edlx, il load up few max depth for the mag and check for pressure signs and check for accuracy

Just to buck the trend, My experience with ELDX projectiles is that they often don't mind a bit of jump, I loaded 145gn eldx in both 270win and wsm in Sako a7 rifles and the mag on those doesn't allow you to seat them anywhere near the lands.
I'm currently working up a load for my 30 06 with 178gn eldx I am at the stage where I will be doing a seating depth ladder, hopefully I get a chance to get some data back this weekend.
Feel free to have a look at my thread.

Your not referring to a tikka 7RM are you? If you are throw the jump out the window and load to mag legnth

Even if not a tikka every tikka has proven with its short mag and long throat 162 eldx is no stranger to jump so id throw out the piece of paper that you wrote it down on load to mag legnth and be happy

it is what it is......you could single feed...may as well use a single shot.... OR single feed first round and have mag full of feedables... lots and lots and lots of rifles have lots of jump ..heck a rossi .308 you simply cannot do it,not enough left in the case... weatherby rifles used to have large jump ...might still do so???

Its a case of having measured and now knowing playing on the mind if not measured not knowing no questions

Yes a rem mag. Sorry I left out a bit of info

Right very straight foward . Forget what you think you no. (No offence ment even if it sounds offensive)but that knowledge isnt going to to be necessary start at mag length you "shouldnt" be disappointed iv loaded for countless tikka 7RM a sako a7 and my own sako finnlight and a remington 700 atr using the tikkas mag as my oal all outstanding

Shooting group went well. Last shot the bolt was ever so slightly harder to open but still pulled it up with out being forced.

Attachment 228278tightend it up well thanks guys

Brilliant good shooting

Second that. Excellent.

Very tidy, was that at mag length or saami length ? If your bolt was a little tight be interesting to know what your velocity is at now ? You could back off the charge in .2gn increments if you are close to or above max pressure to give you peace of mind if concerned.
Hot rod loads are all good if carefully worked up to but they are hard on brass and throats.
No hate man that's a brilliant group. :thumbsup:

Mag length, 3.370 overall managed to work in my tikka mag, think il just stick to these ones I'm thinking. Been mucking around for a while so happy with these ones..thanks everyone for their input iv taken it all on board!

And that's just one group of the first ones iv shot, I havnt shot any more of this exact load... it might of just been a fluke haha. Will test run out at longer range and see how they perform on paper.

I could give you a loan until you can replace a box of 100

Thanks mate these ones got seem to be good so il just run with this new recipe. Just want something half decent for my hunting set up

Same 70.5 gn of 2217 load?

Yea mate same but with different primer and seating depth. Havnt verified speed out at distance yet Sunday was too foggy
