H335 in Rem 260

[SVT_Tactical]

Anyone had any success with Hodgdon H335 in 260? I have a lot of H335 at my disposable and thinking it might be an alternative to varget which I have limited supply of and can't find. Groups with varget and 120SMKs is .5MOA and hoping I can keep a similar group. Wanted to hear others loads. I know I need to just test myself but wanted a starting point from folks. Or experience.

one reason i want this to work is it throws so much more consistent than varget in my redding 3 BR measure.

It will certainly work. I would suggest working your load up during warm temperatures as it’s one of those that hot temps and a hot chamber with max loads will pop a primer. I have the tee shirt.
I would think with lighter bullets it would perform well speed wise.

In your place, i would try out the H380 instead.
H335 may give you a poor filling and some jumps in Vo.

The H380 has some similarities with Vihta 540 and Reload Swiss RS 52 ( i use the latter ) and gives a much better fill rate than H335.
I don't know about temperature stabillity with Hogdon powders, but be carefull there and start with a conservative load.

I have a older copy of HANDLOADER around here someplace that has a story about H335. The guy that wrote the article said it is very stable until you approach maximum load density, then it has a tendency to get real erratic. He had an African game rifle (I think it was a 450 Ackley)that he was using H335 in when he was looking for a better replacement for WW748. He said that everything in his load developement was going fine until he reached maximum load density. At max load when he touched it off, all hell broke loose. He set the locking lugs back and had to set the barrel back two threads to correct the head space. The horizontal cross wire in the scope broke, and there was another expensive repair as well. He likened H335 to "the little girl, with the curl" when she was good, she was oh-so good, but when she was bad, she was horrid.

Follow up - loaded up 5 rounds or various charge weights both by weight and then did the same last using volume using a redding 3br measure.

Huge improvement noticed with the loads utilizing volume vs weight.

Overall powder worked very well. Think with the accuracy in seeing using h335 and the fact I'm below max pressures I should be OK. Going to still measure speeds and SD. Positive results so far.

This is the load I think I'll try to duplicate from the testing

And the equipment

Looks like you got it figured out Bro. Nice rig and great shooting as well.
