My 7600 35 Whelen shoots the 200 grn Core-Lockt Remington factory load very well. Attempting to duplicate the factory load, I purchased the same Remington 200 grn Core-Lockt bullets in bulk and loaded a test cartridge crimping on the cannelure or crimping groove. It just did not look right, the loaded dummy cartridge is noticeably shorter than the factory load and the cannelure appears "high" on the bullet, immediately prior to the tapered part of the bullet. By contrast, the factory load, again crimped at the cannelure, appears to have more of the shank visible behind the cannelure. Sorru I can't post pictures but I am going to pull a factory load and compare the cannelure placement on the two bullets. Has anyone else encountered this or can offer advice? Thanks for any help.
35 Whelen, 200 grn Core-Lockt Question
- Thread starter hiredgun
- Start date
They do look a bit weird loaded to the crimp groove with it so high but I have used them on deer out of my Rem 700 in 35 Whelen AI and they worked great for me. I have never bought any factory loaded 200 gr ammo so I didn't know there was a difference.
Is this a round nose bullet you are using? If so it may be intended for use in the 35 Remington and the cannelure is located for crimping using a lever action. I see no real need for a crimp at all for your rifle although you want to just roll the case mouth down a bit with the crimper to smooth feeding.
Silverback: O.K. then I'm guessing the cannelure is intended for a short action rifle magazine cartridge, possibly 350 Rem or 358 Win. In any event it isn't essential to crimp it hard and many Whelen's have fairly long throats. I would seat it out to fit the magazine provided it chambers and still has an adequate amount of bullet shank in the neck.
stocker, I never even thought about the 350 Rem, you are probably right on the money there. I usually go by the the old minimum no less than 1 caliber length for seating bullets if I want them out further up to magazine length as you also said, seems to work so far.

The Remington bullets in question are the 200 grn Remington PSP (Pointed soft point) Core-Lokt's. The description on the factory load is "200 gr Core-Lokt PTD Soft Point R35WHI" The bulk bullets are described as "35 Cal (358 Dia) 200 Gr PSP Box of 100 Core-Loct 22920 (100)"
I pulled a factory load and found that the cannelure is markedly "lower" ie closer to the base than the bulk bullets. I will get out the calipers and actually measure the difference. Obviously the factory loads are longer and I know (and two caribou know as well) that they feed fine through the 7600 mag. It seems logical that with the bulk bullets loaded at the cannelure, there will be less room for powder and the bullet will have to "jump" more to reach the rifling. Can anyone advise if I should seat to the cannelure or make the finished cartridges the same length as the factory load, or does it matter at all? Thanks for any advice.

hiredgun: Thought we had given the answer but you aren't quite getting it. Yes, seat it out as long as the magazine, action and chamber will tolerate provided you have about one bullet diameter (.358) of seating depth in the case neck. This may well be identical to their factory load if the ogive of the bullets is identical. Make up some dummy loads and cycle them from magazine into chamber and ensure easy extraction of a dummy cartridge just as if you wanted to extract and eject a live round. Adjust your dies so the full cycle of loading in magazine, feeding and extracting is smooth. It might well work seated to the cannelure but accuracy may be improved by having the longer cartridge.
Remington probably rolls on the cannelure as a last step in manufacture of each bullet. The ones they load for factory use have the cannelure adjusted for the individual cartridge they are loading as they usually apply a factory crimp. The ones they sold you from bulk stock had the cannelure rolled in at a point appropriate for a shorter actioned rifle such as the Model 7 in 350 Rem mag. Sort of a one size fits all regardless of the cannelure location.
Good luck with it.

The two bullets in question ARE different. A 200gr corelokt in loaded ammunition is different that when you buy they same bullet in bulk unloaded ammunition. Don't asky me why, and don't ask me to make sense of it although I found this a when pulling some bullets from a Factory 35 whelen 200gr PSP and then trying to use them in my 200gr PSP hanloads for my 358. One is slighly longer than the other.
