  1. Yes you can use the Universal load of 16.0 grs. of Alliant 2400 in the 7 x 57 with cast bullets equal for the caliber like in the 140 to 170 gr. range. You have probably read this article before http://castboolits.gunloads.com/showthread.php?13425-Cast-Bullet-Loads-for-Military-Rifles-Article I know what you mean,I get that a lot on a few forums where individuals never shoot cast loads in rifles let alone use fast burning pistol and shotgun powders. Of course you will only see those type loads if you have access to a Lyman reloading manual and it's even more detailed with many more options if you have a copy of one of the Lyman Cast Bullet reloading manuals. The Universal Load I linked to above is by Ed Harris who wrote the NRA cast bullet manual as well as all the following supplements. He was also a Tech so to speak for Ruger for many year before retiring and is still alive and well as I have communicated with him on several occasion concerning some load date and info on some bullet molds. 2400 is a very useful powder to me not only do I use it in my 357 mag. cast loads but I shoot it in my cast loads in my SKS rifles my Mosins and the 300 Sav. I also use Bullseye in all the above rifle cartridges as well including my 30-30 shooting a little Lee 90 gr. tumble lube SWC for sub-sonic plinker/small game loads. In my Sav. 30-30 pump gun I either shoot the Bullseye plinker load or I shoot a Lee 170 gr. RNFP with the gas check left off and use a midrange load of 7.0 grs. of Alliant Red Dot @1200+ fps. For full house loads I gas check the same bullet and use 30 grs. of H-335 which give me around the same velocity of a standard 170 gr. RNFP jacketed bullet. Lyman didn't start listing the 7 x 57 in there cast bullet loadings until I think it was the #48 manual The only bullet Lyman list is #287641 160 gr. bullet. Most accurate load is with 20.0 grs. of AA-5744 the starting load but I think you will find the 16.0 grs. of 2400 to be just as good and at around the same MV @ 1600+ fps. Of course there are other powders that will get that velocity higher if you like close to the 2K range or slightly over. The AA powder would do that as well as IMR-3031. Here are a few other mold choices for the 7mm. http://noebulletmolds.com/NV/index.php?cPath=29&osCsid=j355m0fog0lgmeqm88ti49bro2 http://www.precisionreloading.com/mm5/merchant.mvc?Screen=PROD&Store_Code=PRE&Product_Code=LE90360&Category_Code=RIFLE_MOLDS
  2. AZ the rifle was bought in the early 70's and has probably less the 300 rds. some factory and some handloads through it but I haven't ever experienced any extractor issues with the rifle as they have all been positive and with authority but thanks for the tip,I will keep that in mine. Honestly I doubt that I will ever load up any more jacketed rds. for this rifle I have around 50 150 gr. Hornady SST's and two boxes of Rem. Core-Lokt ammo a friend gave me when I let him borrow the rifle one deer season but that about it. For the ranges you can hunt around here 100 yds. is consider a long shot on deer size game and my 170 gr. cast bullet loads will cover that nicely.
  3. Finally had a Sat. a couple weeks ago that I could take the old Sav, 99 in 300 Sav. out and shoot some cast loads I have been wanting to test out for awhile. Commercial brass is still available and I have a few hundred pieces of that but that's to easy. A friend last year give me around 100 pieces of Lake City 1991 7.62 x 51 mm NATO brass of which the parent case is the .308 Win. which was derived from the 300 Sav. original so it's a fairly easy conversion to take the X 51 NATO brass back to 300 Sav. The good thing about converting the 7.62 NATO brass is that it's thicker and will last a long time as well as having slightly less case capacity using my moderate loads I gain about 100 extra fps. muzzle velocity with the same loads used in a standard .308 Win converted case or 300 Sav. case. I basically run the NATO cases through a 30-06 FL resizing dies to resize the base first and not touch the shoulder or neck of the case at all. Next I run the case up through the 300 Sav. FL resizing die and reform the shoulder them trim the case neck to the correct length and finally I remove the primer pocket crimp with my little Hornady crimp remover tool. I shot two different loads one was the Lee 150 gr. RNFP gas check bullet and the Lee 160 gr. RN tumble lube bullet I shoot in my Mosins and SKS rifle. Both bullets are gas checked and sized to .311" and loaded with the C.E. Harris Universal load of 16.0 grs. of Alliant 2400. Here are the two 5 shot test groups I shot Sat. with the two loads. I shot guiet afew groups but they were all pretty much the same so I just posted one of each bulet weight.
  4. Trail Boss is a bulky powder mainly designed for low velocity/pressure pistol and rifle lead bullet cowboy action shooting. However it will work in reduced velocity jackated bullet rifle loads as well,runs about $16 average for a 9 oz. container. I've never used the powder as there are better option out there for us bullet caster and shooters for reduced velocity loads. The Lyman Cast Bullet Manuals #3 and the newer #4 will have lots of options using fast to med fast burning pistol and shotgun powders. Two of my favorites are the Lee 32 cal. 90 gr. SWC size down to .311" in any of my 30 cal. US rifles and .314' in my Russian rifles,it basically turns any of my 7.62 rifles in a nice plinker or small game getter. In the 7.62 x 39 I use 3.0 grs. of Alliant Bullseye in all other larger cases from 30-30,300 Sav.,7.62 x 54r and 308 or .06 I use 3.0 to 3.5 grs of Bullseye,no filler is needed with these loads. These are not MAX loads but the little slugs are and can be cast from pure lead and leading may become an issue if you push them much faster and accuracy degrades. MV usually runs around 900 to 1K fps. depending on the charge weight used and groups in general run 2" or less at 50 yds. My other plinker load I like to use in my 30-30 is the Lee 150 or 170 gr. gas check RNFP bullet cast for plain wheel weights for plinker loads I just give the bullet once coat of thinned down Lee Alox before and after sizing and leave the gas check off. For this load I use 7.0 grs. of Alliant Red Dot which gives me a MV or around 1200 fps. Other powders will work as well with the same 170 gr. bullet. There are lots of option as to powder and bullet weights and styles but you will have to get a copy of the Lyman Cast Bullet manual to get that data. 170 gr. cast bullets Red Dot 6.5 grs. 1159 fps. 8.5 grs. 1348 fps. Unique 7.0 grs. 1240 fps. 10.6 grs. 1555 fps. SR-4756 7.0 grs. 1102 fps. 10.5 grs. 1423 fps. W231 6.0 grs. 1175 fps. 8.0 grs. 1275 fps.
