62 grain steel penetrator load

Loading 62 grain steel penetrator bullets with hodgdon 335 data says 22.5 to 25 grains going out tomorrow do some testing fps and accuracy any ideas about loads.
 
With the 55grs varmint bullets (speer TnT), I usually find joy at 26.0 to 26.4 grains seated at mag length (5.56mm chamber LC Brass).
Provided you have no pressure signs I suspect the close to 25.0 grs will net the best results for you.

Thanks I loaded about 50 bullets 24.5 to25 gains I'll test tomorrow chronograph for FPS and check the accuracy after tomorrow I'll get my FPS and adjust from there, Thanks

Shot my 55 grain fmj 25 gains 335 average fps 55 grain 2800 fps then shot the steel penetrator 62 grain 24 grain average fps 2500 both went through the steel pipe "motorcycle a little more powder grains for the 55 fmj did the same as "steel penetrator " glad they weren't expensive, a little more speed works just fine first picture entry 2nd exit

Your right just a little more speed didn't need steel penetrator bullets, just make what I have faster I did do a couple of bullets 26 grains and 26
5
just over 3000 fps

After I shot 26 and 26.5 no pressure problems, always looking at the primer pocket, that's what I was told "still learning "
 
@223Animal
H335 is reported to be the old LC arsenal WCC844 powder for the m193 service rifle load.
When you get out of that lot number back off again and work back to safe. As there is a small variance in different Lots.
 
I do alot of testing, retired life, starting low and work up never had any pressure problems I try to get around 3000 fps that's my sweet spot accuracy seems perfect never had any pressure problems 3000 fps is what I want don't need any more. Bought 2 8lb bottles of pulled powder never had any problems shoots like hodgdon 335 I use nosler load data I try moving my loads up and down once I get the 3000 fps I stop it's what I want. Works for me

Hey SGT looked in my Lyman reloading book found 55 grain 223 hogdon 335 24.3 to 27 max alot of people say too much I've tested up to 26 no pressure problems fps about 3000+

Keep in mind that there is a up to 16% deviance (voluntary) in powder lots, depending on manufacturer.
Do they attempt less than that sure they do.
That being said doesn't mean anything except as a cautionary statement when changing lots or working up loads. Simply recheck the new lots. Or any change of components, seating length, brass, etc etc.

Chambering tolerances, bullet ogive designs / profile, bullet seating length, and caution has actually caused many data publishers to back off (reduce recommended max loads) from the older data. But if worked up properly some have exceed today's advised maximums, some have created bombs by not adhering to caution.
I don't think I would go to 27.0 grs 26.4grs is my personal max using thrown charges.
Even then I'll do at least a 50% check on deviance, less if I'm at 26.0grs or less, best if using a powder measure to check the deviation, no two measures are the same. Hence the 4 different powder measure on my bench, I'll use the one that deviates the least for that charge and powder. most of the time it not the same measure every time Your mileage will vary usually or may be the same.

Elmer Keith comes to mind here, that man blew up more 38 specials, 45 Colt and 44 specials than I care to count in his quest to get more from them.

Of course there is a exception I have one NRA Match AR I will not discuss it's loading nor share, and no it doesn't have a factory chamber. But it did get a new bolt prior to every match, which means I start over again to validate pressure. I have sheared lugs in a match with it on the long line, hence the at least a new bolt each match routine or both bolt and barrel that I used to do. But I have not fired a NRA HP / DCM match for quite a bit. So it's diet is way more subtle than in the past.

Looking at 25.5 to 26 max check the primer pocket so far no sign of problem
 
The caution is directed at those observing the thread, not just at you. Many will not consider the differences, nor accept the consequences of their actions.
Just load it and fire. In a tight chamber, or if it's not cleaned on a regular basis, a quite negative result may occur.

A question for you, what grains would you load the 62 Grain steel penetrator bullets for my AR just curious what you think?
 
Everything I looked at seems 23 24 25 I'll check the fps personally I think 24 if I get close to 2700 I'm done 24 grains is probably where I'll stay love being retired have fun and do what I want "safely "
 
Prepping for tomorrow loaded 23,24,25,25.5,and 26 I think 26 as a max should do I'll get the fps make sure there's no pressure problems if there's no pressure problems I'll load a couple 26.4 right now I have 4 of each number, I'll check primer pockets and all internals keep ya posted. After thinking about im stopping at 26 ,26.4 is a good thought but 26 is good for me.

62 grain steel penetrator
Average of 4 rounds
23 grains 2695
24 grains. 2910
25 grains. 3113
26 grains. 3185
26.4 grains 3251
No pressure problems best feeling was 25 grains not real accurate regular 55 grains much better

As a reloader, I dont understand what "best feeling " means.

I simply try to achieve the best accuracy with the highest velocity while maintaining that accuracy and with no pressure signs on primers or brass. I simply follow the science.
I'm not trying to pick on you. Just concerned for your safety even though I don't know you.
