Q1 Planning to load some 30'06 down to around 30-30 using H4895. The Hodgdon data suggests WinLR primers for reduced loads. Can I use CCI 200 or Fed 210? I was reading...

http://www.sksboards.com/smf/index.php?topic=56422.0 Seems pretty thorough and they suggest CCI 200 for H4895. Then comes...

Q2 In the same article they suggest not to use Fed primers in semi automatics. I've been getting great results with Fed 210 with IMR 4064 and TSX 180 gr in my BAR. Barnes has Fed 210 in their published load data for 180 gr. Am I going into dangerous territory?

Any advice would be appreciated. Thanks...YT
 
Hodgdon has reduced youth loads Using H4895

What type of rifle are you going to shoot them in ?

Some reduced loads will not seal the case = dirtier action/ brass

Make sure all bullets leave the barrel (especially on light loads)

Switching primers with a max load will have more of the risk of having problem than a med or light load

Why the reduced load ?? New shooter ?? or just less recoil for plinking so you can do more shooting ?
 
New shooter/hunter...coast blacktail deer. Thought I would start at 33 grains H4895 and hope to get about 2100 fps. 60% of max is about 29 gr. Plan to use 168 gr Speer not the 180 I said above. Switch to TSX when we get serious. Brno bolt action rifle.
 
Winchester primers are hotter then cci primers and will ignite some powders better then others, they also have a softer cup the cci and require less firing pin force to ignite.

As for using federal primers in a semi auto..........well federal primer cups are the softest primers out of all of them, and do not take a lot of force to ignite, if there is dirt on your bolt face, or if you have a floating firing pin or if your primers are seated proud there is risk of the primer being struck before the round is fully chambered the bolt locked up in battery, this causes a lot of damage to ones rifle and off hand.......the other side of federal primers in semi auto rifles is that the case is supported in the chamber for a split second before the bolt disengages and the case is extracted from the chamber, federal primers are so soft that they may blow out of the back of the case from the pressure in the barrel, you can get a bit of gas in the face and your rifle will short stroke.

Sometime ago Ganderite did a primer comparison and took pictures while shooting them in a revolver out in the dark, you can see just which primers burn hotter, these are better for ball powders, large cases of slow powders and reduced loads....
 
Thanks for the info. It seems I can use CCI 210 for both my applications. Even my hunting load is pretty mild - 46 gr of IMR 4064 with TSX 180's. It may be that the specification of Win primers in the Hodgdon data relates to the fact the companies are related. I will try lighter bullets as suggested (also suggested by Hodgdon in for their 4895 reduced load recipes) if there is still too much recoil with the 168's. It's just that the heavier bullets might be a better choice in the timber where we hunt.
 
Federal large rifle primers have the same cup thickness as everybody else's. Using standard Federal small rifle primers in a semiauto might be iffy, due to their thin cup, which is why they have recently released an "AR match" primer.

Whichever primer you decide to use, make sure your primers are fully seated to avoid slamfires.
