Cholla Posted November 23, 2020 Posted November 23, 2020 A local shop has a stock of LR Magnum primers. Good idea/Bad idea for BP on a .45-70? I do not know the brand just yet.
Boulder Canyon Bob# 32052L Posted November 23, 2020 Posted November 23, 2020 That's what I use, they work just fine.
Doc Coles SASS 1188 Posted November 23, 2020 Posted November 23, 2020 Used em for decades. Buy all they will sell you.
The Original Lumpy Gritz Posted November 23, 2020 Posted November 23, 2020 Not the best. But, if that's all they have-get'em. Std L/R primers give lower ES in velocity. OLG
Jabez Cowboy,SASS # 50129 Posted November 23, 2020 Posted November 23, 2020 They work just fine ... Jabez Cowboy
Tom Bullweed Posted November 23, 2020 Posted November 23, 2020 I try to use magnum primers for all bp/sub loads.
SOUTH-PACIFIC,SASS #59402 Posted November 23, 2020 Posted November 23, 2020 i use lg rifle and trail boss no problem going bang
Kid Rich Posted November 23, 2020 Posted November 23, 2020 If you are shooting Plainsman or something similar use whatever you can get. If you are shooting Long Range use CCI LR, BR2. They are a bit pricey but the most consistent. kR
Bailey Creek,5759 Posted November 23, 2020 Posted November 23, 2020 I use Large Rifle Magnum Bench Rest Primers for Long Range .
Cholla Posted November 24, 2020 Author Posted November 24, 2020 Thanks all. Against all odds I was able to pick up a brick of Winchester LR Magnum primers at a local shop.
John Boy Posted November 24, 2020 Posted November 24, 2020 OK Grit’s, it’s you and me not in agreement with this thread ... *. Magnum primers with a long flash are going to blast the BP powder column like a Sherman Tank creating a large briance that will disrupt the powder column * The objective igniting a BP powder column is to have a low briance because BP does not explode, it deflagurates *. To create this low briance, there is a large number of match BPCR shooters that use CCI BR-2 primers or even Federal LP primers, both which throw a shorter lower briance flame than magnums I shoot a lot of BPCR calibers and this is why my primer inventory now is over 4500 CCI BR-2 bench rest primers For Cowboy though with the short distances..... any primer available can be used to ignite BP because there are really no long distances that require low briance for accuracy

But, if that's all you can find. Better than not shoot'n. Put a double wad of white coffee filter paper on the inside bottom of the case to muffle the spark a bit? OLG

Mark Flint #31954 LIFE said: Do not do this as it can lead to a hangfire Disagree 110% A paper disc over the primer pocket at the bottom of the case in BPCR loading, has been proven to lower ES in velocity what in turn reduces vertical stringing. This is a common procedure in BPCR loading. OLG
John Boy Posted November 25, 2020 Posted November 25, 2020 Grit’s, your giving BPCR secrets away .... now, if folks want to put the paper wad in a magnum primer loaded round .... a regular LR or LP primer
Cholla Posted November 25, 2020 Author Posted November 25, 2020 The more I learn the more I think I should just sell the Sharps...

Smokeless or BP there is a lot to learn if you want to shoot well at long range. You need to pick up a couple of good books.

I think I need to find someone local that is into this to watch and learn from. I have not read anything about coffee filters in my books so that's a new twist.

Have you looked over the Shiloh Sharps Forum? The coffee filter deal is just part of loading match grade BPCR ammo. Not a necessity.... OLG
Snakebite Posted November 25, 2020 Posted November 25, 2020 I used standard LR primers in my 45-70 BP loads. In my 38-55 BP loads I used standard LP primers.

I will get this worked out.

I have not read anything about coffee filters in my books so that's a new twist. Cholla- and you won't. Very few experienced BPCR community shooters are on the SASS Wire .exclusively on the Shiloh Forum. Register and one can learn a lot. PS: construction paper and cigarette paper also works in the case in front of the primer hole. I've found it even reduces the briance more using CCI BR-2 primers And wads come in all different flavors too: LDPE of various thicknesses, card board, cork, lubed felt (my favorite), fiber etc. and one can ever reduce fouling by putting a 1/16 or 3/8" lube wad before the wads used against the bullet base and a thin wad behind the lubed one Here's a good trick to determine if one has to champher the case mouth - pull a fish hook UP inside the case and if it hangs up, the case has burrs that are needed to be LIGHTLY champhered off for shooting accuracy - don't grind the mouth down to a razors edge. One more for your inventory, for accuracy, expand the case so there is 0.001 to 0.002 tension on the seated bullet
